Invest in 2 types of coins.
1st type : Coins that belong to top 100 coins in coinmarket.com. Lisk, Vertcoin and Walton are pretty impressive.
2nd type: Coins that belong out of top 100 coins and are positioned to hit the top 100. Nebilo, Modum, Request Network and Quantstamp. These coins are cheap and I believe their prices will increase a lot in 2018.
