for some reason i prefer Litecoin. I don't know the more technical stuff, but i consider it a low cost form of bitcoin without too much fees. I have around a little more than half of it, so i don't think i am qualified as someone to talk :P

Also, i believe ripple will have a future. I have 0, i want to buy some, i don't know it's uses but what i know is that banks are behind it. That in my dictionary means profit not because i trust the banks and these people but i trust their greed
