No one has the full knowledge of bitcoin, talk more to having an institute that issues out certificate on bitcoin course. Bitcoin is very broad that it can't be learnt for three years. Nobody will care of your certificate if you want to be employed to a company because the employer believes on what you gat in you as bitcoin is not theory but practical especially the programmers and dev. Certificate is only paper and anyone can come up with a certificate on blockchain claiming to be a professional which might not be true. The only one that can have an institute on bitcoin that will be recognized by the world is Satoshi but this is impossible. I will prefer to learn in this forum gradually for a very long time than going to pay for some paper that I don't know if I can grab a lot of knowledge on bitcoin from them.
