I have just 3 here in my wallets that i am personally holding for future purposes because i know that these things are gonna make my long term investment that will turn me into a millionaire. Bitcoins isbthe first of course it is already given but the next one are ethereum and ripple yes you heard it right. I trust some predictions that in the year 2018 they will now start to pump just like what bitcoins are doing they are the two coins that are behind bitcoins and according to some experts they are gonna be huge in the next year so i am so excited from it.
