As many think “crypto will make me rich” it’s definitely not going to be Bitcoin. Even if it hits a new ATH and you buy here at $24K, you will maybe make 3x. Unless you buy millions you won’t get rich this way.
Bitcoin and ETH would of made you rich back in 2015 or so. You could of invested $10K in both and would of made great sums of money as long as you held. Gone are those days.
Not sure about other cryptocurrencies and how they may work and how they can make people rich because there are many other cryptocurrencies that may have pump dump and after that, some people can get rich if they invest enough in it and they have the knowledge of the cryptocurrencies. But speaking of bitcoin, I don't think investing just a few dollars on bitcoin can make anyone rich even in long term, to be more realistic bitcoin has grown up and reached many high prices but you cannot expect to see investing a few dollars on bitcoin make anyone rich in this time.
