While no one knows the future, history indicates massive drop after the fork as the total marketcap of a single coin before fork and 2 coins after fork are typically the same. The growth happens after that.
With BTCP ZCL mining fund paying people up to 5 BTCP for a single ZCL mined, it sound like there is a TON of premine in BTCP which means a ton of DUMP after the fork. So invest carefully in a coin that was less than $2 just 6 days ago. IF this is a true 1:1 fork, then how the FK do the pool owners pay out up to 5 BTCP for a single ZCL mined?
