There are some really good altcoin that are worth hodling for a long term. As a matter of fact, altcoins, are the new best thing for a lot of investors. Many investors have resorted to just investing in altcoins, cos they feel it yields to better profits. I like advising people to invest in ethereum, and Ripple, amongst many other good altcoins.
Every time Altcoin has started a lot of good ones and can develop well so that they are good for investment, you really say that ripple and of course that is undeniably proven that ethereum is a very good altcoin for example neo and others.
