Well, trading on different exchanges is not that easy, you should look for the market on every asset that you hold. Much better to use some Trading Algorithms to make our trading easier. As of now, I use
Mudrex. They have the most advanced trading strategy builder coupled with a fast back-testing engine to create, test and deploy your trading strategies. You could try this one.
I am not trading in different exchange just selling my coin depend which one exchange listing, I think easy although you use more than 10 exchange together because you can check and update price on coingecko or coinmarketcap to know how much price with your coin, I think almost exchange have the same value with some coin and become easy how to know which one exchange have good worth value.
