I still have to learn "stop loss" I guess though too, as I'm not wanting to lose much of my $20 if I can help it.
that is the best thing to learn but also don't be too hard on yourself about it because it is nearly impossible sometimes to set a proper one for altcoins since they can be extremely volatile and they can have down and ups which can trigger an undesired stop loss. but at the same time it is a necessity.
having a better speculation of the ongoing trends can help a lot in this case.
