In my opinion, if you want to trade crypto with low risk using an exchange like Binance, you can buy crypto such as Bitcoin, or Ethereum at a low price and sell it when the price is high, even though the value of the asset may fall, we still have the asset in the wallet on the exchange, but if If you want to trade using leverage with higher risk, you can use a CFD broker service that offers CFD Crypto trading. There may be several brokers who offer Crypto CFDs, of which I know there is FXOpen, but specifically in the UK and AU FXOpen for crypto CFDs is only available to professional clients and not to retail traders because they comply with the rules of the FCA and ASIC regulators
