I think bounty all the time unpredictable, no one can know how much can gain.
And i can say if this happen, then it is bad luck
Except bitcoin bounties. Bitcoin is fixed and you do not have to worry about all the altcoin worries like will it get listed? Will it have a lot of trading volume and liquidity? Will the developers continue to work on it? Will it get mainstream adoption?
With BTC you only need to worry about price, and that is not a big worry at all for hodler like me:)
