After BTC OG insider whale agent Garrett Jin showed off 200,000 ZEC, worth $300M in spot holdings, he probably realized shorting wouldn't catch any fish. In the end, he closed all ZEC short positions, with a total loss of about $35M. Now Garrett is likely in a fully long position, holding nearly 1% of the total supply. Pushing it up further might be a bit tough. Unless this guy switched accounts to continue shorting for a hedge.
