I like the title says "fiat is the best alternative", that is really cool. Think about it, in his mind, fiat is the "alternative", and here I am thinking bitcoin was the alternative for fiat all along! . All jokes aside we all know bitcoin is not going to 5k, even if we have a huge crash the price is not going to 5k, its impossible.

However let me tell you the time I talked with an accountant who was great in finance game and made a lot of money from stock trading as well, he believed bitcoin will become zero and eventually everyone will get out. Why? Because he believed "it has no value, so it worths nothing" and as you can believe, just like every other old heads who believe that something needs to have a physical value behind it, something that supports that price, otherwise it means nothing. That was 5 years ago, we had 2 huge bull runs (one in 2017 and one this year) since he said that and we peaked at 64k, if he invested he could have made x100+ from bitcoin.
