But bitcoin ETF 3X is very risky, just like those products like BTC 3X long on exchanges that are listed under the spot market. You can say it will give more liquidity, but the first thing you should think about is liquidation and how risky they are. I have been seeing some news about it recently I think in August or early September.
If you think a Bitcoin 3x ETF is risky, what do you have to say about people who use 10x leverage, up to 100x leverage on crypto exchanges right now? The ETF is for people who need more exposure to Bitcoin but have limited capital. The 3x ETF gets them there, and it's fundamentally different from the use of leverage on exchanges.
This type of ETF already exists in TradFi, and people use it a lot.
