Many friends are interested in products like dual-currency winning. To put it simply, this thing is just futures logic wrapped in a financial management shell; the essence hasn't changed. Currently, mainstream exchanges all have similar products with good maturity and a large user base. However, here is a suggestion—if you're not an options expert, just focus on the two main cryptocurrencies, BTC and ETH, as the risks are more controllable. If you really want to trade options, then go directly to the options section, which actually saves the middleman fee. All major platforms support this; the choice depends on personal preference.
