Still, now new altcoin is being created, but they don't use BTCtalk anymore.
and here's all bounty's are scam.
Then what they use now?
Maybe you just chosen the wrong bounties and you ended up not paid by the one that you have participated. There are still good bounties that I see and paying their participants, just choose wisely.
Not all of them are scam especially if the manager is good in handling and choosing projects to manage.
