I don't think that we can become rich in a short period of time. If we chase this goal, we are more likely to lose as it looks like gambling where only 1-2% of people are lucky to earn.
We had better focus on long-term constant capital building by holding mainstream currencies and different defi-projects such as staking and yield farming platforms, so be patient and don’t chase quick money.
There are lucky traders that have been caught by hype and they've managed to become rich in a very short period of time. But the risk is with them and it's the highest because those projects that they're trading, they're likely to dump at the lowest that it can.
That's why if you're aiming to be a rich person through cryptocurrencies, you have to do it with the moderate method. You'll become rich if you're too good but don't be too hasty.
