Presumably because it is being used at Cryptohub as a coin for devs to pay for their introduced-coins to be represented there (but, in some part perhaps, because it might seem to be a coin with a low risk-to-reward ratio right now [CROC represents a low-Beta coin relative to the overall cryptocurrency-market -- in stock-trading jargon/nomenclature -- particularly as BTC seems to be in a downtrending channel after the latter's run-up in late 2017]). When the appropriate effort and testing has been made, we are intending to fork the coin (hopefully as painlessly as possible) to make use of the Peercoin codebase (an indirect ancestor of CROC), modified to CROC's specifications. I'd say the outward lack of activity is largely my own as I've been a little too much caught up in mining in my freetime (and work 50+ hour weeks) but have a few resources at hand (an in-depth C++ book to get reacquainted with this programming language, and [more recently] this very thorough and technical book with code samples and theory: https://www.packtpub.com/big-data-and-business-intelligence/mastering-blockchain).
BTW, please use the current thread: https://bitcointalksearch.org/topic/anncroc-official-crocodilecash-update-board-strength-in-basking-2326144 -- as we can't update the original post here since Gizzard seems to have pulled a Satoshi.
I would also be very careful with pumps on that exchange. Literally any coin even with a dead blockchain can pump there and if you get in because you think it'll go higher it stops pumping out of a sudden :/
