I think it is hard to find coins to HODL for the full of 2018 since the crypto industry is such an ever changing place but at least for the first half my bigger holds are:
1. DeepOnion
2. Neo
3. Ethos
4. ARK
Of course I have more coins than this but these are my bigger holdings that I think will grow in the beginning of 2018. I think it will be the time of the small cap coins going forward since a lot of new people are again coming into crypto. The word has certainly come out, I see Memes on BitCoin everywhere (not all positive but who cares) and as more and more come in they will hear about ALTs and how they are the future. There will surely be a lot fo pump and dumps so it will be important to find the coins that have a solid technological background and great marketing. Keep posting your picks, it is very interesting to read. Great thread!
It really exciting to see all undervalued coins are coming out from the shadow of know coins by next year.
Im just holding PCC and FUDD at this time since it is not recognized by some investors that it's price are in the bottom line. and I believe that 2018 will be the year for them and I'll be rewarded of what I did.
I am completely on board with Ark and Neo, solid coins with great tech and a realworld use (something investors will be taking more seriously in 2018). On the privacy coin front I would look at Spectrecoin, risen from $0.40 to £3.50 in a month because people are finding out about its solid tech.
