The dev already contacted the exchanges regarding this matter, they already informed them that they need to update their wallet to make sure users are receiving the real coins and not the fake ones that were generated during the zerocoin exploit but unfortunately upto this very moment, exchanges are still not updating their wallets. The dev already did their part so right now, we are just waiting for the exchanges to also do their part so that this coin can finally resume trading. I think cryptopia is having so much issues at this moment that's why upto now they are still not working on the smartcash's wallet update. I just hope that everything will be sort out sooner, because it's quite a shame to see this coin receive scam accusations just because exchanges are still not updating their wallet. The dev is very hardworking towards developing this coin and moving this project forward so reading messages from people accusing the dev for something that isn't his fault but the exchanges fault is quite unfortunate.
