I think about a great opportunity people had miss when Bitcoin was still in a lower price, imagine how many people Bitcoin would have made a millionaire, though by then most people were a bit skeptical about the growth of Bitcoin, if it has a good potential or save to invest.
If people had known Bitcoin will surge this way almost fifty or more percent of world population would have become a millionaire.
I love research, please share you knowledge.
I disagree with you. There are still a lot of people who knew about BTC since 2015, invested in it and yet didn't become millionaires.
Meanwhile, there are people who embrace it late, but have made millions within this very short time.
