I think the x10 and x100's of several altcoins/platforms are to be seen in 2018
Enjoy the ride brothers and sisters
With all the shitcoins coming around, I'm sure that we can find at least the proverbial "needle in a haystick" in 2018. New shitcoins arrived, lots of hype around it, investors get interested, pump-and-dump and then BOOM x100's in few days. Book your profit and then look for the next, that's how it is. But the questions is how we gonna find out that one coin that will make us all rich? Would be interesting isn't it?
And to the existing coins, I still go with the top 1-10 in coinmarketcap. I think they are still undervalued this year because of the China ban ICO's and of course the bitcoin sweepstakes that we are seeing. I myself have some ETH that I didn't dump event though is reaches its all-time-high this year. I'm looking at 2018 as the year of the altcoins. Lots of project around, lots of IT companies interested, specially smart contracts. Let's see though. Just watch the top 1-5 this year, it would be huge.
