I think potential coin 2017 is feathercoin, wings, etherum and also doge just wait and see that coin will be up go to moon

to me if you want to get huge gain in 2018 you need to invest your assets in Tor coin, because Tor has great potential to increase future and currently its price is trading as low, but very soon it is going to gain accelerator and will start increasing, therefore investing in Tor coin righ now will be more profitable in future.
