👁️ Payment confirmation and exchange delays: how understanding the process saves time and reduces stress

A BestChange user created and paid for an order with an exchange service found on our platform.

The payment system used by the exchange service did not automatically register the user’s transaction. To complete the exchange, the payment needed to be confirmed manually, so the exchanger requested supporting documents from the user.

Expectation:

The user clarified which specific details would be suitable to confirm the payment—a bank statement, receipt, the transaction’s RRN (Retrieval Reference Number), payment status, and settlement timeframe—and promptly requested these from their bank.
The user then submitted the information to the exchange service. The service identified and confirmed the transaction and completed the exchange within 15 minutes.

🟢 Processing time: 15 minutes.


Reality:

1️⃣ The user considered the request excessive and refused to provide the information.
2️⃣ Throughout the day, the user repeatedly contacted both the exchange service and BestChange support, insisting that since the funds had already been debited, the exchange should be completed without additional requirements.
3️⃣ The exchange service was unable to proceed, as the transaction required manual identification through the payment provider.
4️⃣ We clarified the situation with the exchange service and confirmed the issue.
5️⃣ Then, we explained to the user the reasons for the request and the verification procedure, and outlined what information could be provided. We also emphasized that such requests are part of a standard procedure and are handled in accordance with security and confidentiality requirements.
6️⃣ Only toward the end of the day did the user accept the explanation. Then they submitted the information to the exchange service. The service identified and confirmed the transaction and completed the exchange within 15 minutes.

Processing time: 1 business day + 15 minutes

🥰 Conclusion:

Even standard procedures can raise concern when users encounter them for the first time. That is why, in our ‘Case Studies’ series, we break down real scenarios and explain such situations in advance—so your exchanges proceed with a clear understanding of the process, and therefore without unnecessary delays.

Recent developments in the cryptocurrency industry
​
🖱️ Over the past few days, Bitcoin has gained roughly 7%. According to CoinMarketCap, the leading cryptocurrency is now trading at around $71,700. Ethereum has risen by more than 6%, reaching $2,190. As analysts at CryptoQuant previously noted, the rally in digital assets followed Donald Trump’s statement on a two-week ceasefire between the United States and Iran. In their view, this triggered a stronger cryptocurrency price surge in just 24 hours than the market had seen in over a month. CryptoQuant also said that open interest in perpetual Bitcoin and Ethereum futures increased by $2.1 billion and $2.2 billion, respectively.

🖱️ Stablecoins are gradually evolving from a niche asset into a core instrument in the international payments market. Over the next 10 years, the volume of transfers conducted in such currencies could reach $1.5 quadrillion, according to analysts at Chainalysis. “The great wealth transfer is here, and it’s bringing crypto with it. Between 2028 and 2048, an estimated $100 trillion will likely move to younger, crypto-native generations,” the analysts said. They also suggested that stablecoin payment volumes could match those of Visa and Mastercard by the end of the year.

👩‍💻 The New York Times claims that bitcoin creator Satoshi Nakamoto is most likely British cryptographer and Blockstream co-founder Adam Back. The new investigation involved a large-scale analysis of more than 130,000 messages from old mailing lists featuring both Nakamoto and Back. In the investigation conducted by journalist John Carreyrou, the analysis compared writing style, spelling, choice of epithets, and other linguistic markers. As a result, the author concluded that Back is the most likely creator of the flagship cryptocurrency. Back himself, however, denies the claim. According to the entrepreneur, all of the so-called evidence is merely coincidental.

👀 Byzantine Fault Tolerance (BFT)

The ability of a system to continue operating correctly and reach consensus even if some participants make mistakes, send false information, or act maliciously. The system remains secure as long as malicious or faulty participants make up less than one-third of the total number.

In blockchains, Byzantine fault tolerance is achieved through consensus mechanisms: nodes verify one another and reach agreement without needing to trust each other directly. This allows the system to function correctly even when some participants provide conflicting or false information.

The term “Byzantine” comes from the Byzantine Generals Problem. This is a logical problem in which several generals surrounding a city must decide together whether to attack or retreat. They communicate through messengers, but some generals or messengers may be traitors or deliver false information.

Digital asset market developments at the start of the week

👩‍💻 Bitcoin fell below the $71,000 mark following the failed U.S.-Iran peace talks held in Islamabad on April 12. However, some analysts say there is no immediate reason for panic. The flagship cryptocurrency remains relatively resilient, holding above key technical support levels, as investors continue to view it as a digital hedge amid the risk of escalating tensions in the Persian Gulf.

👩‍💻 Meanwhile, Bitcoin Depot reported a cyberattack on its corporate infrastructure. According to the company, hackers stole credentials for settlement accounts in late March and withdrew approximately 50.9 BTC from its wallets, with losses estimated at around $3.6 million. Bitcoin Depot said the breach was limited to its internal systems and did not affect customer data or the operation of its ATM network, which includes more than 25,000 machines and BDCheckout service points worldwide.

👩‍💻 Justin Sun has criticized the crypto project World Liberty Financial, which is linked to the Trump family, calling it “a trap door marketed as an open door.” Sun, who previously invested about $75 million in WLFI tokens, said key risks had not been disclosed to investors. “What was never disclosed—to me or to any investor—is that World Liberty embedded a backdoor blacklisting function in the smart contract used to deploy WLFI tokens. This function gives the Company unilateral power to freeze, restrict, and effectively confiscate the property rights of any token holder, without notice, without cause, and without recourse,” Sun posted.

👁️ Older BTC addresses at risk: Bitcoin network upgrade and protection against quantum attacks

The crypto community is debating one of the most radical proposals in recent years—a Bitcoin network upgrade that could directly affect holders of older wallets.

The proposal outli nes the transition to post-quantum cryptography under BIP-361, designed to prepare the network in advance for the arrival of quantum computers that could target Bitcoin’s current signatures.

📱 What Bitcoin developers are proposing

➡️ Phase A disallows sending funds to old, and therefore vulnerable, addresses. The estimated implementation timeline is three years.
➡️ Phase B completely shuts down the current signature algorithms (ECDSA and Schnorr). All legacy wallets that have not been upgraded could lose the ability to spend their funds. This phase is expected to begin two years after Phase A.
➡️ Phase C involves quantum-safe recovery of legacy addresses. One option under consideration is proof of possession through a corresponding seed phrase, although the mechanism has not yet been finalized, and no implementation date has been set.

Why is this being discussed now?

Developers cite several reasons, including:

👩‍💻 quantum technologies are advancing faster than expected;
👩‍💻 34% of BTC is already potentially vulnerable because of exposed public keys;
👩‍💻 a quantum attack could go unnoticed, with stolen funds being moved only later and in small amounts;
👩‍💻 the ecosystem needs time to upgrade, and without a clear deadline, the process could drag on.

For now, this is only a proposal; any real implementation remains a long way off. But the very fact that it has emerged suggests that serious preparations are beginning for a new category of risk.

And what is your take? Would the proposed upgrade protect the market, or create new problems?

Recent developments in the cryptocurrency market

✅ The market has entered a prolonged ‘crypto winter,’ according to a report by CoinGecko. The downturn has been driven by a sharp decline in asset prices, reduced trading activity, and worsening investor sentiment in Q1 2026. CoinGecko analysts believe the crypto sector has come under pressure amid a sustained bearish trend since late 2025, driven by global geopolitical tensions and macroeconomic uncertainty. The total cryptocurrency market capitalization fell by 20% in the first three months of the year, and the industry has been struggling to recover since then.

✅ Circle co-founder Jeremy Allaire sees ‘tremendous opportunity’ for a yuan-backed stablecoin. He suggested that China could launch such a product within three to five years, despite its generally strict stance on cryptocurrencies. Circle also expects continued growth for its USDC, particularly amid the U.S.–Iran conflict and broader geopolitical risks. Allaire highlights that China wants to expand the role of the yuan in the global financial system, and stablecoins have become a tool for ‘exporting’ currencies by simplifying cross-border payments.

✅ Bitcoin is currently trading near the $75,000 level. On-chain data indicates significant investor accumulation, even as the asset has repeatedly faced resistance around $70,000. Pseudonymous analyst Crypto Patel said that large holders have purchased around 270,000 BTC over the past 30 days, marking the most substantial accumulation phase since 2013.

🙃 Hash function

A mathematical algorithm that converts input data of any size (such as a word, password, phrase, array, or file) into a fixed-length output string. In the crypto space, hash functions are used:

- to form and verify blocks in a blockchain;
- to link new blocks to previous ones;
- in mining, to find a valid value when creating a new block;
- to generate transaction identifiers.

What happened in the digital asset industry over the weekend

✅ Stablecoins at the current stage of adoption don’t appear to have a strong impact on the financial system. However, banks may face increasing competition and a shrinking market share as the capitalization of the crypto industry grows. “So far, the use of stablecoins remains limited, but their market capitalization exceeded $300 billion at the end of last year,” Abhi Srivastava of Moody’s Investors Service told Cointelegraph. He added that stablecoins are gaining importance in payments, international trade, and online finance, while noting that U.S. payment systems are already ‘fast, low-cost and trusted.’

1️⃣ Bitcoin’s price declined over the weekend, retreating from levels reached at the end of last week. On Friday, April 17, the cryptocurrency hit its highest level since early February—above $78,000—but by Monday morning it had fallen to around $74,000. According to CoinMarketCap, Bitcoin is currently trading at approximately $75,100. Analysts at Santiment have previously warned of a potential FOMO among retail investors if bitcoin surpasses the $92,000 mark.

👩‍💻 Former Goldman Sachs executive and Real Vision co-founder Raoul Pal said banks are likely to favor Ethereum in the near term. He cited the network’s reliability, resilience, and scalability. Senior figures across the crypto industry are increasingly highlighting Ethereum’s role in traditional finance, while banks typically avoid untested technologies, preferring infrastructure with a long track record, high liquidity, strong developer support, and clear security standards—areas where Ethereum stands out.

🥰 AML Check Payment Error: How BestChange Helps Resolve Even Minor Issues

A user paid for a crypto address check in the AML analyzer on the BestChange website but did not receive the report—neither on the service page nor via the email provided during checkout. The user then contacted BestChange support.

👩‍💻 BestChange actions

Step 1. We requested the transaction hash from the user.
Step 2. During the review, we found that the payment had been made via a wrong network—different from the one recommended for the AML check.
Step 3. We specified the payment details and matched the transaction to the corresponding AML check request.
Step 4. After verification, the payment was successfully recognized, and the AML report was delivered to the user.
This case may seem minor, especially given the relatively low cost of an AML check. However, the BestChange support service treats every user request with the same level of attention, regardless of how insignificant it may appear.

By the way, you may notice that this case does not include a ‘What the user did’ section—because resolving the issue only required the user to provide the transaction hash. Everything else was handled by our team.

👩‍💻 Key takeaways

To receive your AML check results without delays, it is important to send funds using the exact network specified in your selected payment method. In some cases, using the wrong network may even result in a loss of funds.
If an error does occur, contact BestChange support. We will do our best to assist and ensure the payment is properly processed and the AML check is completed.

There is also a simpler way to avoid such situations: BestChange vouchers. You can purchase a voucher in advance for any number of checks that suit your needs. When making a payment, simply choose the voucher option, enter the code, and click ‘Redeem voucher’—no need to send funds again or select a network.

🥰 What market participants have been discussing this week

✅ ​The supply of bitcoin on Binance has fallen to a three-year low, suggesting investor accumulation. Analysts at CryptoQuant reported a steady outflow of the flagship digital asset from the exchange into cold storage or private wallets. They believe market participants are now less inclined to sell their holdings, preferring to accumulate them instead. The trend is viewed as positive, as a reduction in liquid supply on exchanges limits potential selling pressure.

✅ This year, traditional finance and distributed ledger technology have begun converging into a single infrastructure, according to analysts at CoinShares in a report released jointly with Token Terminal. “Public blockchains are settling institutional assets. Wall Street asset managers are issuing funds on Ethereum. <...> Bitcoin catalysed this convergence by proving that a blockchain-native asset could earn institutional trust and deliver portfolio utility at scale. Hybrid Finance is what comes next,” the analysts noted.

✅ Tether has announced the freezing of more than $344 million in USDT at the request of U.S. authorities. The funds were frozen in two wallets linked to illegal activity. In a statement, the company said it works with more than 340 law enforcement agencies across 65 countries. That cooperation has helped support more than 2,300 investigations worldwide and led to the freezing of over $4.4 billion in assets. “USDT is not a safe haven for illicit activity,” said Tether CEO Paolo Ardoino.
