You didn't flip any account. You burnt it. That's the right expression as you diminished what you were supposed to have grown above the starting capital of $100.
- Trading every coin instead of choosing a few that I could understand their movement
This is the easiest way to lose one's account. Trading every coin leads to not mastering how they relate with price. It breeds confusion. I was once in that shoe until I got burnt several times and learnt my lessons the hard way. To this day, I trade just few pairs, and it's usually one at a time. I do not pick more than a trade at once.
