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.
The purpose of such certificates is not to turn anyone into a full-blown Bitcoin developer, but to certify that you have a basic understanding of what Bitcoin is and how it works.
I'm guessing their target group is professional firms wanting to train their employees to help them better understand what is all about if their jobs require any kind of dealings with crypto. Or it might be a good way to boost up your CV with something that'll make you stand out from others.
