I would say Ethereum, Waves, Ripple, Litecoin, Stellar and Dash would be some of my options. In fact, I have them at my portfolio right now, and I am holding some of them for future profit. These coins, to me, are reliable in terms of keeping their value even in those times when the market is going haywire. Also, they have shown good movements since its onset, and many people also see them as potential-filled coins.
