From the start of bounty I am sure it takes more than 3 months to finish the bounty campaigns itself and then you can expect the payments in next month or so if things workout well. Once the period of distribution is over then also you might say that you have not got what you need unless and until you exchange the tokens for real money otherwise what is the use holding tokens with no meaning or value to it. So you may need to wait for another month or so until they come and hit the exchangers. That would be your actual finish line and yes it do takes more than 6 months many times.
