With so many cryptos exploding recently, I don wonder how much juice this train has left. A couple picks I really like in 2018, will be in the Data Storage Sector, I think this will be an early sector to explode into real world use, The top three of these are STORJ, MAID and SIA.
I also think the underground gaming/gambling industry will take off in 2018. 2 of my favorite altcoins for this industry is Funfair and Auger.
Lastly,
I think Ripple Will continue its run and become larger than bitcoin in the near future. and I like SUB as an alternative to web browsing and trading once the government start to regulate the trade.

Thank you!
