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.
