I think your portfolio is very good, altcoin that you invest has good growth potential. My favorite is Ethereum and Ripple. Ethereum is the queen of the market, it has excellent blockchain technology. Most ICO projects use the ERC20 platform. On the ripple, this is the altcoin that I enjoyed. It has a very large capitalization, ranked 3rd in the market. Ripple is not appreciated by many people, I think because the ripple is managed. However, for me, the ripple is one of the altcoin worth to invest. Many banks use ripples in transactions, this is the advantage of ripple.
