Trading is different then investing, first you should determine if you are going to trade or invest. Investing is buying and holding for years, trading is simply buying and selling to make a profit regardless or the fundamentals of a coin.

Figure out which coins you like and buy and hold them dont trade them, on the other hand find coins you think will go up in maybe a couple of months and try and trade those.

Stop losses and indicators are something you should become familiar with and remember trading has a lot of emotion involved, dont let your emotions get the best of you. Good luck
