It seems like you are assured of the next big wins that will make you rich because of how you constructed your first sentence. Or are you really confident that just 2 or 3 coins is enough to achieve the fortune which someone is looking? Anyways, it is true that crypto is not quick rich scheme (most of the times), but there are some people who are lucky enough or let's say held their coin until the very good time in which they can sell it in much much higher price. Not all people are lucky so do not have a high expectation that you'll be one of them soon as you invested for in crypto.
I think that getting rich through crypto depends on the strategy that each person adopts. For example, traders may be lucky in the new currencies and gain large profits as a result of a sudden rise in the price of one of the currencies. Also, long-term holders can get large profits over time, and by looking at the Bitcoin price chart, for example, it is certain that many early users have become wealthy if they have never used their currencies.
They are all relative and there is no clear way for any user to become rich using crypto. Many use crypto for daily transactions and not for other purposes.
