WE LAUNCH IN 45 MINUTES

TeachYourselfCrypto course verified certificates and private community

Add Crypto to your resume

Companies are looking for crypto-literate professionals to join their teams. Most of these companies offer pay in 6 figures, with remote-WFH options available, consistent with the crypto culture.

Even traditional companies are looking for individuals who can spearhead blockchain adoption in their company. You don't need to be a developer for this, but you do need to know how to use the tools.

Getting certified by TeachYourselfCrypto allows you to showcase your knowledge on a cutting edge, fast paced topic, while communicating to prospective employers that you have the skills, foresight and competence to adapt to a fast changing environment.

The community is a place to learn more about crypto, connect with other members, and communicate with other crypto-literate people (i.e. not like twitter where everyone is an expert on everything.)

If you buy before launch (use code "preorder"), you get 50% off on all certificates and lifetime access to the private community.

We launch in 45 minutes!
