Always trading on spot.
Spot is less risky, future is riskier.
What you think the risk more dangerous, Future or Perpetual?
They are both dangerous with higher leverage. The difference is that futures will close itself is the date set has expired, but perpetual has no closing date.
Is ETF like BNB3X is included in derivative?
I do not know anything about those coins that assuming 2 or 3 times the price of a coin, I have only seen something like that when I was using Coinomi and looked like it is linked to Binance, but I do not see anything like that on Binance..
If we want doing derivative trading, is borrowing money is must?
Let me assume leverage trading is divided into 2:
- margin trading
- derivative trading
If you want to borrow, you will use margin trading. You can go 3x for isolated margin and 10x for cross margin on most exchanges. Margin trading uses spot price.
Future and perpetual are both derivative trading. They both use derived price of the future and perpetual price. Yiu can go up to 75x, 125x and even 200x on some exchanges. But it is very risky. Millikns of dollars can be liquidaed in seconds, minutes or bours if uskng high leverage.
