Have lost so much money on coins that doesn't work well for me. My flaws are I'm impatient and ignorant this maybe a good time to find some insight and good answers on how to get better
If it does not work for you then this is the time to stop it, there is not much of a point to do something in which you are not good and even worse in which you are losing so much money as you describe, so take sometime and see if you can correct your mistakes and if you are unable it may be a good idea to leave trading definitively.
On some point you are right but not always the best solution for you to stop.Its normal for us to struggle at first since we do lack of knowledge on all the things we do first encounter which means we do need to learn up.This is why its always been suggested to start out on small amounts rather than on hurrying up yourself on putting huge sums and rushing out for bigger returns because this would eventually the things would failed you down.
