After doing some research on the matter I came to the conclusion that trading stable coins isn't a bad idea after all. For those who are unfamiliar with this, for example you buy tether at $0.99xx and sell it back at $1-$1.01xx it's clear that it is less risky than most other pairs but it came to my mind that these 2 transactions are simple to automate and can be more lucrative if automated so for you folks know a trading bot that supports this?
I don't think this is a good idea. because if you are trading for profit with such a huge difference, then you need to have quite a large amount of capital. So why don't we buy usdt and sell it on the black market, even more profitable when using the bot. When you trade on an exchange, every transaction you lose about 0.07% - 0.12%. so I think this option is not satisfactory.
