Best Altcoin for 2018? Without a doubt, marinecoin! for the following reasons:

• Low marketcap (less than 1mUSD), so there is potential for growth
  
• Been around for years, unlike some coins that have no real history
  
• Excellent dev team currently pushing the project forward
  
• Anybody who qualifies (up to the first 20,000 people) will get 450k MTC airdropped, so the investment is risk free
  

How many altcoins currently meet the above criteria?

MTC is currently airdropping 450k coins to the first 20,000 people that apply and qualify for the airdrop. It's been around for a long time (since 2013, that's like donkey years), and the devs are currently working hard at the core. For example it now provides IoT and AI support amongst others. Most airdrops are brand new coins with no track record or history, unlike MTC.

Marinecoin (MTC) definitely has the potential to grow 100 times. It's current marketcap is less than 1mUSD, and for it to grow 100x, that implies a marketcap of 100mUSD which is not unheard of for cryptocurrencies.  The top 130 cryptocoins on coinmarketcap all have market caps of more than 100mUSD. And the best thing is that marinecoin is currently giving out 450k MTCs for free via airdrop for the first 20,000 people that apply and qualify. Head to marineco.in for more details on this
