Try to invest at the very low price with btc or altcoins and check if it is rising, when it rise you are already earning. Your earnings varies from your capital and from the price of your coin. You will lesrn more from trying hard on how to trade but do not get panic when the price goes down.
Thank you for the advice and I'm trying to do the similar thing which you guys have suggested, sometimes I win some and sometimes lose but I'm not gonna leave, I'll learn more and more each day to commit less mistakes next time.
