Thanks for your comment, unfortunately at the moment I'm thinking about continuing with Stake only
Since you will send the bot a tip from Stake, there are no fees on that, and for actual exchange bot uses its own liquidity.
Given that it's used mostly for small amounts, handling that is not much of an issue
$500 is not such a small amount for some people, but maybe you dont see tips that high so often

So let me see if I understand correctly, you are using your Stake account for accepting tips from other Stake customers, and then you later exchange coins you received for different coins, with small fee.
