Hm, interesting idea, but a long way to go until we actually have a product like this. Much luck though!
I clicked on the article because I wanted to share what can also be used when trying to minimize fees. Switchain is one of those services that compare fees between a few exchanges and give you the best deal. Highly recommended.
It sounds like a very interesting tool, especially in those times of trouble where we want to buy/sell fast hahahaha
Thanks for comment!
