Am looking for the technical aspects of trading what are the tools needed to build a good trading career.
Well, now OP can say that he has some experience in trading, he got into trading with serious money and he lost, but we can hope that he learned something while he was losing all that money! I guess he thought that with some serious capital it will be easy to make money with lucky guessing, probably he got into the wrong coins at the wrong time, and he was impatient to wait for those coins to gain some momentum... if you sell with a loss every time after some time your capital will melt!
He just needs to follow some suggestions from this topic, how to choose a pair and follow it for a while, to see the best timing for trading that pair, to learn more about that pair, it's called research... with lucky guessing, nobody made a fortune in the long run.
