I agree with you that all these coins are very good and they are not shitcoins, but look on its graphic, they have dumped up to 90%, I don't think they will grow so much in the future.

SodaCoin (SODA) is one of the best cryptocurrency to invest in 2018.

It is a brand new coin with the support of its growing community of stakers and holders and traders.  

There is no definite answer. Both crypto-currencies have great potential and their disadvantages are balanced. It is better to buy both cryptocurrencies

I think TOP 10 of cryptocurrencies are interesting to invest. I like ETH. Altcoin...I think there are too many cryptos, like 2gether, Peculium (AIEVE), ...

there are so many good project that launched at the end of 2017 and 2018 but couldnt priced up because of this bearish market ongoing for 7 8 months. i can say bluzelle, wanchain and iota can be good choices for 2018.

Now the whole market is red, and all the encryption prices are not high. Under this premise, I think every coin with a good community and concept is worth investing. Of course, I mean the coins in the true sense or Tokens, Not the shitcoin produced by Faker ICO

Dash has a bitcoin-like pattern that is different in some points but not very important. Mainly about the technical part is the main. If you want to learn more about Dash you can find out on the net.
With Dash, people usually see this as a channel to avoid bullets when the bitcoin goes down. So when Bitcoin goes down, Dash prices rise again and vice versa.

The new altcoins appears every day. I think we should look into it and see what we got. Because some of them may become a really valuable to end of the year.

There are a lot of new coins and a lot of really good ones. In my opinion, still the best cryptocurrency so far will be bitcoin and nothing else
