There are many good buying opportunities. I'm following McAfee,(McAfee twitter):
Digibyte (DGB). Using a Blockchain which is 40 times faster than Bitcoin and having one of the most decentralized mining systems in the world - based on 5 different synergistic algorithms. DGB adherents call the coin "The Sleeping Giant". https://twitter.com/officialmcafee/status/944929837671690241
Reddcoin (RDD) - a sleeper - most widely used social network coin in the world - flying under the radar since 2014. Working with every Social Media platform, it is the only currency that many children under the age of 10 have ever known. https://twitter.com/officialmcafee/status/944555048880746497
BURST -- First truly Green coin and most overlooked coin. Uses 400 times less power than Bitcoin. Super secure and private. Includes smart contracts, encrypted messaging, decentralized wallet, libertine blockchain. Most undervalued coin. https://twitter.com/officialmcafee/status/944206175100424193
