Heres my picks for 2018 and why:
1. ZCoin- great technology, privacy trend, low market cap
2. ZRX - Interoperability, low market cap, great team
3. Bitcoin Private- bitcoin + privacy= win
What are your picks?
You seem to like privacy coins. Have you checked out DarkPayCoin? They are a M/N PoS Privacy coin with less than 0.1% premine that is going for an organic growth strategy of having the growth coming from MasterNodes and Staking. They have accomplished a lot in a short time because they have a really good community behind them. You should give them a look.
