Yes, I agree with your point because I am a victim of it. I sold Velic coin after receiving the bounty payment, now the price has increased x2! I sold simplybrand token, then it gained 87 %! My friend sold QNT coin at 1.8$ then it becomes 4 USD! Therefore recent harmony already gained x9, so, bounty hunter should hodl the bounty reward at least 2 months! This is my personal opinion!
Yes, I think because now Bitcoin has experienced a very good increase, so that ICO Tokens or other altcoins are brave enough to increase their prices, so hunters must now hold on to their assets.
Unfortunately it's not happening yet, ICO tokens and small altcoins still does not have enough improvement like we expect it to grow.
Bitcoin has been very stable moving up now, in fact, it looks like it's gonna breach $10,000 soon, as of this time, Bitcoin is already trading at $9500, that means we only need a little push to bring the price into double digit. Experts said that range will start a FOMO, well, let's hope.
