I'm one such greedy and keep tokens in the hope that they will grow up? Usually, even with bounty I do not sell for 5-10 months. This tactic cost me a lot. 
I feel that mate, looks like if getting longer holding bounty token/coin, the worth is getting cheaper. This time, It's rarely to see a token/coin that more day the price is more expensive. I'm myself just can hold it for 1 month, after that the doubts and disappointments will mix, and make me sell them.
