By far, the most sophisticated anon and privacy-focused coin in the crypto world with its zk-SNARKs (zero-knowledge proof cryptography). Vitalik and Snowden vouch for Zcash and Zooko is behind it and there is a dedicated group of experienced cryptographers and engineers working on it. Yes, sometimes, you have to sacrifice a little bit of decentralized feature in exchange for centralized efficiency.
Now that the controversial founder's reward is gone and the high inflation rate is cut in half after the November's halving, I expect ZEC fundamental to be strengthened which will in turn attract more investors.
Dash (check my Dash posts below) may have more daily active addresses and transaction per day than ZEC, but ZEC has the highest daily transaction volume among the big three anon/privacy-focused coins (ZEC, XMR, DASH).
Weekly chart has just turned bullish as shown by most technical indicators. ZEC seems like it's ready for the breakout as it's extremely undervalued.
Time to accumulate ZEC and place the stoploss below $50.
Just my opinion. Not the investment advice.
