Is there any software or platform to trade coins in chains. For example buying bitcoin when it is low, and it then automatically waits for another coin to get low (ripple for example) and then buy thousands of these. Waiting a bit more to get ripple high and then cash out again? I think it is a lot of trickery so that is why i am curious if it would really work out, and how?
also interested if someone knows something about it.
You mean a way to obtain such a script? For which exchange do you need that done? Most of them offer API integration so you could make a script yourself that does what you ask for or simply look up the internet for someone who has done so already (if you have little knowledge about programming). If you provide more info I could help you.
Btw check my previous answer on this same thread before putting your money at risk!
