Take some courses and then try prop-trading. That's a good opportunity to get in without starting capital.
Also I recommend using tickers with high liquidity
Well, I dont suggest taking courses for becoming a trader. People are really becoming good traders simply by practicing it. There are many people who are all the time reading about crypto market, its trends and principle. These people keep developing strategies which help them understanding the market in best possible way. You can never learn better form any other source than learning from your own mistakes.
Reading about the market is a good thing to start with. The rest could include doing trades on your own, learning transfer methods, making analysis about price movements etc.
