Waves has an amazzing project in hands and a lot potencial to replace eth or became a huge rival when we talking about ICO with the huge difference you can benefict from waves tokens, since the fees will return to you in the end. I do believe raiblocks, XRB is unique as well, instant transactions and no fees, some say its the competitor of Iota, the coin has been made from the scratch and has a nice and active team working into it.
