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.
Leveraged ETFs aren't meant for the average investor.
They're not even meant to be held more than 1 trading session because they reset at the end of the day. Meaning that it's more of a trading tool for expert account managers. You buy them at some point in the trading session and sell them at another, or short them, if you believe there's going to be some moves. The fact that bitcoin markets are open 24/7 while stock market's aren't makes these even more risky for that matter though.
Nobody with the ability or knowledge to buy actual BTC should actually touch these instruments imo.
