there is no real strategy to become rich fast. Therefore you need luck. lots of luck. So read in, buy a few promising coins, take a few free coins with you and hold 2-3 years. than, maybe, buy new ones...
Do not try to get rich fast in crypto world, you can also high likely to get poor fast. Instead try to build a solid portfolio and think ahead, this is the only true way to get rich but it requires a solid brain which most ones in crypto don't have.
