Have you ever done any daytrading (traditional stocks)? Daytrading cryptocoins is not like daytrading stocks, the markets behave quite a bit differently. It's also nothing like poker.
I have been successfully trading cryptocoins for a quite a while now and I would recommend the following steps:
1. Attend some conferences or watch some conference recordings. It's important that you understand the underlying concepts, terminology, etc. to cryptocoins, and the industry they operate in. Personally, I feel attending conferences in person is far superior to watching anything on youtube.
2. Keep on top of cryptocoin news. Twitter is essential, so is this forum.
3. Invest a significant amount of your time to watching how the markets behave, correlations to certain market behaviors, understanding the industry as a whole, etc.
4. Start small - it's easy to grow even a small amount of capital when you've successfully learned how to trade crypto coins. You can always invest more when you've demonstrated to yourself that you can perform successfully.
The 4th point is essential, there is no point into trying to invest huge amounts of money when you do not know if you are any good at trading, the best thing is to start small that way if you make a mistake, the mistake is not going to be as costly as that mistake will be if you were trading with all your capital.
