This is definitely the year of other altcoins, and by other altcoins, I mean coins with less than 100mUSD marketcap. One of the coins I really see a lot of potential for is Marinecoin. This is a coin that has been around for more than 4 years, and was once the main rival altcoin to bitcoin. They are currently airdropping 450k MTCs for the first 20,000 people who qualify for the airdrop. As far as I'm concerned, it's the deal of 2018.
