The good Altcoins to invest in today are ETH, NEO, Ripple, and ADA. You buy with a cheap price like this now, I think you can benefit in the long run. Because the price of altcoins that I recommend earlier, the longer the price will go up.
Yes absolutely, these are one of the best altcoins to invest and these are already in top 20 according to coinmarketcap. All have potential to grow more from here and strong technology/network to support them.
