No airdrop is worth the time now. Even if the value itself is in the ICO price, after entering the exchange its value drops to zero. It is not worth even collect it on address, because sooner or later it will be rubbish.. We have to wait for bull run and alt season.
The amount of coins collected in the bounty are very less and they will not be of much value even if the coins hit the exchanges. But if you are free and nothing to do, then there is no harm in collecting these coins but do not make them your hobby and do not expect much from them in terms of value.
