I wouldn't join any future bounties that will lock the coins for a long period. Some projects just collect the money from the ICO then run off while the coins are locked.
it's a bad experience buddy. if everything is in the plan of the developer to lock the coins from the bounty hunter then it doesn't matter because all depends on whether we want to join or not. but if such rules are added and suddenly at the end of the campaign it must be very painful.
Yeah, I joined the project because its value will increase later, not when distributed and sell them immediately. Perhaps many times those projects will die and I completely lose the money I earn, but maybe it will be a bounty for my life
