I would recommend DigiByte. One of the best blockchains and a legit dev with a fantastic vision!
DigiByte is a good coin. There are other good ones such as Bitcoin Cash or the Ethereum, or ZCash.
Please don't jump on the DGB hype-train that 12 year olds are trying to promote. If you want to make some serious money with holding only you should definitely take a look at Nexus, Wagerr, Wbb, Game, MGO or Stratis. Or participate in an ICO although that's way more risky. (Kyber, Chainlink, Guts and even Atlant)
