I bought some "3x short Bitcoin tokens" 7/25/2021 on FTX when the Bitcoin rate was BTC1/$34175 for 329USDT. 1 btc have been around $40000 for a long time now, and currently it's even down to ≈1BTC/22000 but my 3x short Bitcoin position is still currently only worth around 111USDT. I understand it's about time and value of an underlying asset. I also learned about "volatility decay" then there is a fee on this leverage. Furthermore, I don't think btc will fall much under $20000. But how long will it take for my short position to
recover in this bear market, will it ever?
Leveraged tokens are absolutely terrible in the long-term. This is the cost you pay for the "no-liquidation" perk.
Go read up more about them, but they re-balance every day, meaning when the market is not volatile, you lose money, when the market is going up, you lose money.
Honestly, unless you expect bitcoin to repeatedly go down in a manner that each day is a red candle increasing the value of your leveraged token, there's no way you're going to make money.
To put it into perspective, go look up the BTCBULL token price from January 2021 (~30-40k) to Nov 2021 (2nd ATH), and you'll see it also has lost value.
Next time read up on leveraged tokens and how they work.
