Things you should know before using the bot on Binance:
You should enable fees in BNB from your Binance account.
You should buy some BNB to cover the fees.
You should manage your BNB amounts and manually buy more when needed.
You can safely convert the remaining dust to BNB.
Avoid converting to BNB the currencies that you have some small amounts left in the bank monitor, or if you do make sure to manually remove the leftovers from the bank monitor.
