I just made a mistake for shorting $LAB , the funding fee is now -1% every 1 hour.
If you invest a margin $500 and leverage x10, your position size will be $5000, and it will burns your wallet $50 every hour. What happen if the price won't drop in 10 hours, you absolutely lose $500 that equals your margin. It doesn't worth to short it.
Few years ago I had closed my account as I was at loss 2k, at that time I trade anytime anywhere without strategy. Now I am back as my main job with starting capital $1k.
On first day I took 30% ROI and tranferred to my bank account. For who wants to have profit with small movement like me, you can copy trading. I use low leverage and manage risks as much as possible.
