I really and totally agree with what you just said! I participated in a bounty around August 2018 and we were paid weekly but uptill now the coin remain a scam coin. I prefer to participate in a bounty that last very long but at the end I benefit from it as I have do from bounty in the past. However I see all this as luck becouse some of the project we thought are genuine are scam and most time it is at the end of the campaign that we discover this.
I prefer to get paid even though the price of the token dropped dramatically or did not enter the exchange market, than I did not receive the payment, while the token from the project that cheated me turned out to have a high price on the exchange.
