It's a pretty weak list of experts. I've been around for a long time and I only know two of them.
Qualifications like this aren't exactly convincing:
Investor and in the IT industry for 25 years. Researching and being more and more fascinated by blockchain technology for more than 2 years....
Indeed, it's funny to claim an expert in blockchain technology if you are not among the people who have been investing in bitcoin since 2010, here what Steven Buchko said;
No one can predict with more than fifty percent accuracy what the fate of Bitcoin will be in the next five years. Anyone who says that they can is a liar.
He's right, no one can predict it precisely, as no one here can see what happens in the future, especially in the world of cryptocurrency which so volatile. So, forget about the experts said, you may predict what will happen in the future by considering some factors, and the most important is; bitcoin acceptance in every country.
