ETH and IOTA. IOTA may be one of the top altcoins and is modeled after the Internet of things (IoT). It has come a long way in its price as well. Ethereum is amazing because it introduced their own Ethereum network, in which other people can create tokens based on it. It made it easier for developers to create their own tokens, because they don’t need to create an entire blockchain from scratch.

Electroneum , if you look at the position in coinmarketcap, ETN slalu is in the top 70, and now the age of ETN is only about 3 months, and only 1 exchanger ... most likely ETN will enter big exchanger like Bittrex and HitBTC easily

I think it is ethereum and also ripple. Both of these coins have great potential for the future. Ethereum also includes my favorite altcoins. I think investing in both coins is really a boon. That's just my opinion.

My picks are:
SUB and Oyster Pearl, both of them will have an working product until Q1 2018. The coins will moon

Don't forget the undervalued DeepOnion on your list, if you do some research about this project, there are still a lot of features to be released soon.Also, this project has the strongest community among all privacy coins.Never miss out the chance to gain more profit. Grab some now and hold. You will never regret it.

Are we still confident about IOTA?
It has been around for some time now with a lot of buzz, yet I'm not sure if it is living up to its potential. We have been waiting for so long for 10$ levels yet it bounces back and forth between 3-4,5. Or am I impatient?

Today's price correction on many coins is a good chance to buy more out from ETH.
PRice @Viberate - VIB decreased from 65 cents to 50 cents per . Since there is no significant price correction for ETH this is a good time to buy some more VIB with a nice ratio between VIB/ETH.

I would choose XRP and Stellar. Because they have the maximum capitalization for trading! Well, the prospect of growth is good! this is only my opinion!
