I have Vechain right now and will also get some Wanchain, but I'm curious to hear which one you guys think will be bigger in the next 2-3 years?
Venchain for sure, this coin has been made for a long-middle term, if you want to make another x2 or x3 in a near time, just go for venchain.
Wanchain is a newbie coin, it has a low marketcap, and because of this, it can give you more profits in a short term (few weeks - a few months)
I would diversify between both, but it is upto you, i am not interested in any of them anyways.
