I saw a post where someone claimed that he doesn't know if he is investing in Bitcoin or not because he doesn't understand how the market works; he has been investing for two years and hasn't noticed any changes, which demonstrates how greedy the person is.
The person is either lying about his bitcoin investment, or he is expecting returns that only Ponzi schemes and scams can offer. In 2023, which is two years ago, bitcoin price never got up $45k, so if he bought bitcoin at that time till this year, that is over 100% profit in two years because bitcoin got to $123k this year. So even if he doesn't want to invest for the long term, which is the best way, in two years, he should have made a lot of profit. Even people who bought bitcoin around the first quarter of last year have made a 100% profit by now if they didn't touch it.
