low value, meaning it is already listed on an exchange and has a very low price. I sell it more often because most of the altcoin prices obtained from bounties or airdrops will decrease over time. However if the altcoin obtained has not been registered on the exchange, there is no other choice but to hold.
I think OP was talking about ElonCoin of which's signature campaign he's participating. he was asking about that.
I too agree with you that these bounty and airdrop tokens are not worth to be hold for long term. but if they are not listed in any exchanges then there is not any choice.
as soon as they get listed sell them and take your money out.
but there was some bounty and airdrop coins which gained a lot of value after exchange listing because those projects were really good. u can consider that factor too.
