It's his opinion, after all. It's not something that's going to happen, 100% guaranteed.

I think that there is a chance that this may happen. It does not mean that it's going to happen at all, though.

His opinion is probably not going to influence the market that much, meaning that the theory of him wanting to make a quick dollar by saying this kind of bullish news is probably not true. $40k is nearly a quadrupling of the price, and I personally haven't seen any investments be able to sustain hundreds of percent of growth for 2 years in a row. Bitcoin should be no exception.

Alts come and go, they are quite irrelevant.
