What they believe is up to them. I doubt that it'll have that much of a impact on bitcoin price. There are just too many "experts" out there saying a whole range of different and sometimes contradicting info to the public.

I agree with them though. I do think that one day in the future, bitcoin's market capitalization will probably exceed that of gold's. A few years ago if you said that bitcoin would ever be worth the same as one ounce of gold, you were delusional.

When will this happen would be completely unknown. It could take a decade or two before a pump this big happens again.
