DRGN, AION, WAX and QTUM.
Also there are several good new ICOs coming up if you interest to invest on ICOs. Just read the whitepaper of Daneel.io. This is not a trading idea. Before investing do your own research.

In my opinion, there are no such altcoins, because today one well shoots, and tomorrow another. It is necessary to search for working projects of news, etc., and on them to do purchases.

I think Bitcoin and Cardano is the best crpyto to invest in this so far road it is have a lots of potencial skills that shows in the market.

I think Siacoin and Cardano would've been really good choice. Siacoin in marketcap is currently up 8.7% and it can be up to 15% and Cardano currently has position 5 i think will rise to position 4 above Bitcoin Cash.

The coins are new and will surprise us very soon as they did in the past. I'd recommend investing in that coin

Ripple and red pulse

In my opinion, top two altcoins to invest in Ripple & Dent. Because their future is bright.

UNIFY and RUPX.
very low max supply.pos.good coins and community.
unify is up x100(!!) in a few months(from 0.006 to 0.6)
unify has maximum coins of 19 million.marketcap is near 4 million.
bittrex and cex.io are planning to add this coin soon.
10 $ easy by june 2019.

CyberMiles has a great future to grow in value.  5 miles and 5xlab working together to adopt  blockchain  technology to their already existing 12 million US customers. ICO ended in 24 hours raising 84,146.5727 ETH and many investors couldn't participate. My second choice would be an ICO like ArcBlock. ArcBlock - Born for Blockchain 3.0. A platform service, rather than a standalone software package or set of APIs. ICO pre-sale on Jan 12, 2018 or the pubic sale on February 3, 2018.

This New Year is a good year for Cryptocurrency. Because starting from the new year, every Cryptocurrency, which was close to $ 1, was past the 1 $ limit. For me, the two coins that would be the next hit. TRX and TNT are the two cryptocurrencies.
