I would never pay any money for such bullsh*t.
Passing one exam and buying one course doesn't mean that you are a true professional. There must be a 4 year long university program for becoming an expert in cryptocurrencies and blockchain technology. The participants in such program must practice their skills for months or even years. Learning theory is only 20%, building skills by practice must be 80% of the entire crypto/blockchain education.
I guess that those "crypto organizations" OP is mentioning have found an easy way to make some easy money by selling "certificates" to a bunch of gullible crypto noobs.
