How it was optimistic but the market reality seems not looking that great. If Bitcoin price may pump but not actually it will go far, and $15k is much achievable.
I agree with your opinion,
maybe many people expect that will happen soon, at least 1 or 2 years to come. but I myself still don't believe in people who say that. until now the price is still below 9k, and still spinning just under 10k. I think the price will definitely go back up, but to reach 22k I'm still not sure. I speculate that prices will continue to rise within the next year or two, but not more than 20k.
