Really excited to see what happens in the next few weeks with Raiblocks. Imo it should be at least at the same marketcap than IOTA. It does the same thing (p2p instead of m2m) with no fees and almost instant transaction and it doesn't need a coordinator unlike IOTA. I like both project, but Raiblocks has a working product and a great community behind it. Lightning network is a complex system, we still don't know if it will be adopted, but raiblocks is so simple and easy to use, I think it's the best bet on the market right now.
