Then suppose I create a new bot for $1000 on the same currency. Will it use all of the old currency that I had left over before buying any new to fill up to the second $1000 investment?
When creating a gridbot you do have an option in the advanced menu. That option says “BOTH or USDT”. When you click both, it will create the bot using coins and usdt you have. WHen you click just USDT then it will only create the bot using USDT and the coins will not be used.
