Zcash (ZEC) to go to the sky.
ZEC is touted by many for its ability to be mined without ASICS and on various generations of hardware.
ZEC is touted for its privacy as well as its stability. It has the unique ability to mix in the chain while providing to an 'invisible savings account'. Transfers from private address to private address make the anonymnity as much as you do.
My thoughts -- ZEC is destined to beat ETH again (ETH DAG increases, and ICOs and chain-based tokens are its downfall).
Bitcoin only goes so far, and bitcoin cash offers nothing truly unique.
Your input is valued! :)
Have a good day Steemians!
