I try myself to predict the market of the particular cryptocurrency for trading. I don't succeed all the time, because my prediction will be associated of random choice. This means I open up a sell order to get executed for specific price, and if it didn't get executed within the target time I'll change the selling price target cancelling the previous order. Same is being followed at the time of buying. I find it simple as I wasn't completely into day trading.
Oh yeah you reminded me there are sites where you can "play" trade with play money to test how is your learning coming along
People might disagree about my opinion, but personally I'm against trading using play money or to be precise a "demo account". Yeah you can learn something and try out your strategies before implementing it into real-case trading, but you can not experience something like emotional and human nature once you trade with your real own money, the experience is really different.
