I think that the old bounty has been backed up , and it can be add to the new.
I'm going to ask them on their Telegram. ( group you should join.)
Is it true ? so when token sale will end, I feel this bounty is one of the longest bounty I've ever been in. what I see on their webiste is just a bounty of referrals and telegram so whether Bounty tokenmarket will still be paid or not. especially this bounty is not transparent
