You can find alot of instructions about the safe way to choose the good bounty to do in this forum. First of all, i want to ask you know that, the instruction is only for reference, and in the new market like crypto, the important thing you need is the luck. I need luck to win when buy ICO, when trading or do bounty. As my exprience, i will follow some famous and trust bounty manager to do such as: yahoo, krypital, amaziz... on the other hand, when see the new bounty, i will find the informtation about it to read before decide join bounty ot not.
