In the bot usage, we define profit the same as the base fund used in the bot. If you use usdt to run a btc/usdt bot, then increase in usdt means profit for you. If you run grid bot on ADA/BTC Pair, then increase in btc value is considered as profit.
In Reverse grid bot, we use the token as the profit. in btc/usdt reverse grid bot, the profit is quoted in btc, meanwhile reverse grid in ADA/BTC pair quoted in ADA.
