my plan is to keep 6 potential alt coins until year end. at least keep until bull market. specially coins are req,Ada,trx,prl ,cs and snov. I wish two bull markets will come in this year
My suggestion to you, you should use bitcoin.
Bitcoin will benefit you.
But if you are sure once with the 6 coins you mentioned please monitor continuously for the sake of seeing its development.
2018 could be a big year for Litecoin and its planning some impressive updates which could increase the adoption and practicality of Litecoin on a mainstream basis.I will choose Litecoin.
