I have a serious question.  I'm new to crypto.   I saw in 2017 BTC went from 1k to almost 20k and crashed to 3k for the bear cycle.  It finally reached and passed 20k in 2021 (the person who bought at 20K was underwater for 3 years). Was that 20k buyer a dumbass or a genius?  Similarly, is the person who bought at 65K last month a dumbass or a genius?  Thanks.
