Tell me please where you can find the end of the bounty. And can I register in the project if half the time has passed?
Most bounty campaigns will end last day of ICO or reach the hard cap. The bounty manager will announce the date from their bitcointalk bounty thread or telegram bounty group. Next one is yes, You can join any bounty if halftime has passed or last week if they accept. You can find all those details from their bitcointalk bounty thread or bounty telegram group.
