Many coins will explode, sure with many ppl joining crypto world recently. and some ico with real project will release their coin/token in 2018
In my opinion, in the year 2018 ICO projects will be reduced, some governments are banned from poor quality ICO projects and they only implement quality ICO projects. In future altcoin will thrive, but in terms of ICO numbers will decrease. Everyone in the world is more aware of altcoin. and a valuable altcoin will dominate the market. Get rid of the bad altcoin.
