https://www.youtube.com/watch?v=Pubd-spHN-0So Fetch is a bit of a duplicate of IOTA but with yet unknown detail differences. Imitation is the sincerest form of flattery. Competition is always good for the market imo, outside of the basic concept how closely is it related roughly speaking.
I am betting on that Fetch is a project built on top of IOTA.
I can't find Fetch website. Can you please post the link?
