The short answer is no, you can’t buy Ethereum futures. The slightly longer answer is that there are no regulated Ethereum futures markets currently available for trading, so even if you could find an exchange that offered them, it would be very risky to trade them.
The reason you can’t trade Ethereum futures is because Ethereum isn’t a commodity like oil or gold. Commodities have a long history of being traded on futures exchanges, and there are many regulations in place to protect investors.
Ethereum is a new type of asset called a cryptocurrency, and there are very few regulations governing its trading. This makes it very risky to trade, and most exchanges don’t offer it.
There are a few exchanges that do offer Ethereum futures, but they are all unregulated and extremely risky. If you want to trade Ethereum, you’re better off buying the actual currency on a cryptocurrency exchange.
So in conclusion, you can’t buy Ethereum futures because there are no regulated markets for them.
