Yes, in one year coins can bring you very big profits. Even if you are a beginner, then you can buy any coin from the TOP-20 and it will give you a good profit. I am sure that in 2018 there will be a big increase in altcoins.
Well they were all massively pumped between mid December and the first week of January. Almost every coin from what I can see that was on a decent exchange. I'm sure they will continue this process.
