The first 10 coins on the coinmarketcap are the best coins that you can invest and make really good money in years come. Bitcoin, ethereum, ripple, zcash, dash, litecoin and some many other that has good capitalization are some of the coins you can actually invest and make good money. but for me always Bitcoin is the best crypto currency to invest. You may go for Ethereum next to Bitcoin and NEO followed by that. The all time favourite for everyone is Bitcoin but the price of Ethereum is low now and it is a good option to buy now since this coin has good potential and market cap. You may think of NEO as well.
