You can transfer part of your money to Binance saving account. That way you can leave some money untouched. All money that remains on your Spot or Futures wallet will be used when copying a Spot or a Futures strategy.
You can do the same for the other two exchanges — OKX and Bybit. To leave some of the coins untouched you can transfer them to your Funding account on OKX. These two accounts do not participate in copy trading on Coinmatics.
To leave the funds untouched, you can also use a subaccount on the supported exchanges, for example, on the OKX/Bybit exchange.
