The short answer is yes. Only members have access to their wallets on the respective exchanges.
However, when you have selected a strategy to mirror trade, your assets on the specified exchange cannot be lower than the minimum required amount also specified by the strategy. When the amount in your exchange's wallet falls below the minimum required amount, Bincentive would remind you to re-adjust your fund allocations. Failure to meet this requirement within the given time frame would result in a cancelation of your smart contract.
To ensure a smooth investing experience, please confirm you have the minimum required amount in the correct exchange's wallet before selecting a strategy to invest.
