The following coins are my favorite XRP, Stratis,Waves,DGB,ETH and BTC and i am holding these coins in my portfolio. It will give me a big fortune if i can hold them for long term. These all coins have good potential to rise due to their quality projects.
I would go with Bitcoins, ETH, CTX and SUNLIGHT. BTC and ETH are really trustworthy to invest for a long term growth. CarTaxi's project and its team's dedication is so promising to invest in it. Love and wish to support SUNLIGHT Coin's project. Down to Earth. Altcoin created for Orphanages / Orphans. Wish it should get succeeded.
