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.
This shows just how fully integrated Bitcoin is into the financial system. There were already 3X ETFs on the Nasdaq 100, for example. And, yes, they are risky. If things go your way, you make money much faster, but you can also go bust much faster.
One more note: the listing rule is the one that the SEC approved – not the products themselves – so they cannot be traded just yet. They are still awaiting the S-1 registration to go into effect and there's no launch date yet. They also don't hold actual BTC, they use CME futures.
As @slaman29 mentioned, it's not the BTC price that is changing faster, it is the profits and losses of the holder. The "3x" is only valid per day. For example, if BTC goes up 10% then down 10%, the result is -1%, but with a 3x product, up 30% then down 30% gives you -9%. A market that continues to fluctuate in price will steadily erode the value. It's known as volatility decay.
The difference from 3x longs on exchanges is that there's no margin call or liquidation, so the most you can lose is what you put in. <...>]
Those are good points to bear in mind. In any case, even though it is different and there is no margin call or liquidation, it is a product that is obviously riskier than simply holding bitcoin or buying a bitcoin ETF.
