Honestly it would be weird what you said to be true. If you have bought bitcoin 3 years ago (or any other crypto) it would still be in a huge profit even at the bottom a week ago because everything they are doing is not that difficult at all, the prices are still quite high and that is why I do not think that there is nothing that could be true about you said. This is why I think there is something wrong with the calculation probably. You said "it took 3 years to recover" and that sounds like he got in 3 years ago, that is why I said it would be impossible.

Even at the highest bitcoin it was 20k and its still above, eth was 1500 at most and higher, bnb was 40 bucks at most and still higher. Basically everything is higher than 3 years ago so that is why you could be saying something wrong or making a wrong calculation.
