Maybe you can always check Coinmarketcap to see many exchanges you can use to trade future and try your luck.
We have good exchanges like Binance, Bybit, Kucoin, OKX etc that can enable you to trade with less tax and free.
Please make sure you do the necessary research because most of these exchanges are limited in some regions so it's good you try and know where they are limited so you don't get restricted later after you fund your account. There are centralized exchanges.
