I don't think so. Being rich in crypto will need many effort and times. We cannot be rich as soon as possible on overnight if we are new. But, if we have been more time sin crypto and know how to earn the money easily, we can do day-trading that can make you earn so many profits only overnight, probably it will make you rich fast. But, it doesn't really mean that the rich only comes on one night. It need process.
I agree we can't be rich in overnight but im really sure that in short span of time altcoin will help us to become rich but its still depends on the amount of capital we invested because the higher capital invested the higher possibility of earning big profit.
