#ETH just had a violent rise, and I got out of the contract after making half of the profit, and then I opened a 50u light position to go short, set a stop loss, and it was wiped out in less than 2 minutes. Damn, from a bad perspective, I didn't seize the opportunity and earned 200u less, but from a good perspective, if I was shorting now, I would have lost it directly. I'm scared just thinking about it, this market is really unpredictable.
