My friend just told me recently that he is leaving the bounty that we both joined last January. The ICO has been delayed many times and it is getting longer. He said that the longer the bounty period of an ICO, the fewer the coins that you will earn. So it is true based from your experience? Should I also leave or stay?

EDIT:

I already knew the amount of money that I earned on this particular bounty. I think the money that I earned is actually good and enough for my waiting. i waited for about 8 months before they release. Actually it is already in my wallet but the token is not listed yet so I can't know for sure the actual price of the token.
