Zcash has the best underlying privacy technology (zk-snark) and has good corporate backing. I think it will be a leader in getting Crypto accepted and used in business-to-business transactions; Augur is for prediction markets, Golem is for distributed computing.
However,Zcash is really insecure when it comes to privacy.The critics say,they developers indirectly have access to your private keys which is not only bad but a big NO.The price drops in the early stages is enough for me to stay away.
Well, this is actually sad, because it means I can't pick up coins at a cheap price...
You can always pick up the best ones at the current price which would always be cheap when you think of the future.Better yet,pick one of your gems from the new altcoin market.
there will be many who regret not hodling.
How would the exchanges run if everyone only were over possessive about holding ?
