I don't think OP is looking for soccer markets as he already posted an example that is betting on the price of bitcoin.
If OP is not looking for soccer market and only wnat to bet on bitcoin price, he will see that on some trading sites and exchanges which is called option, like th binanry option or the bitcoin option. He can make use of binance for that.
If OP is look for gambling sites that support cryptocurrencies, he can make use of the gambling boards to see many of reputable ones on this forum.
