Of course, day trading is a good trading formula. Many people have got a good income through this formula and many are still going to get a good income. It is a very risky, so everyone cant do it. It takes great courage and money to do this. If you start trading less day with less money, you will lose it because it is very risky. So before start day trading you should learn about crypto market.
Having in risk is the way to make strong in terms of faith and strategies. Though we can't say that all the we can made it or succeed, but we even tried to work on.
You're right, not all of us have such idea and courage, in fact, only 10%(I think) of the population are already engaged in these form of investment and the others are preferred for day job.
