Everything with ZCL is managed pump and dump scheme by Rhett and Bittrex - some made profit from this (include me), some loose much (crypto newbies). Big winner is Rhett, he can retire now (my guess is he made 20+ million fiat, maybe more).

NO ONE care for POW and no dedicated POW correlate with coin price (visible in hundred other coins). Everyone here is for $$$.
This coin never recover. It not have developers on its born (Rhett copy paste original zcash github and change 2 lines of code is not development), after this he leave project (lack of programming knowledge). For BTCP he pay (with pumped money he get from his ZCLs) to lot people for made changes and BTCP sources for him.
I not see any developer who can continue work on ZCL - this is total compromised coin. So this is dead soon (or maybe it hit 1-2 usd value and traded by bots).

For BTCP - no idea what can happen. Very possible it will hit some exchanges (16.8 million BTC is forked, these need to be monetized to fiat).
