I think that the best way to earn Crypto for free is to increase your Bitcointalk membership ranking and then participate in the Bounty programs.
Increase bitcointalk membership ranking is not best way to earn crypto in bounty. Newbie can participate in bounty programs too, i know not all bounty project accept newbie to participate. But they can buy cooper member
And i think there are too much bounty manager is rank newbie with cooper member. Their reward is too huge than participate in bounty
