Can bounty manager answer me if really bounty will be till 31 of December???
Take a look their last point on their general rules :
Bounty program
will end at the same closing time of the token sale. Token sale end is TBD.
after searching on their telegram ,
i don't think they have announced their public sale exact date,
"Main-sale will be on dec 2018"
https://t.me/RaysNetwork/27889You need to wait until they announced the main sale exact date (they said "soon")
