What wallets should i use for altcoins?
Just like what are mentioned by other member, for me Myetherwalllet is the best wallet if you want to stored some altcoins because MEW is very convenient to use whatever you want, like selling your coins and buying some coins.
MEW is a user friendly wallet which many people are like so I prefer to choose MEW because aside from being safe due to it's security features we can easily use for free without worrying our hold tokens investment.
