no it is not. but since this is not the first time an airdrop like this happened and nothing has happened so far, i can say the negative effects are not that big.

besides this is not the only time people get "loads of money out of nowhere". at the beginning of this year every single altcoin was pumped and each of them went up at least twice and some even went up 6000% and that is a lot of "money out of nowhere" for a lot of traders.

not that much actually.
many people never bothered to claim it. many don't even know about it, many don't know how! and many are holding it because they have small amount that is not worth selling or they think it can go up maybe!
the number of transactions shows there aren't really that many who are transferring their BCC to sell.

nothing

it is good because it proves that if people don't want something it will become a useless altcoin and if they want it then nothing can stop it from growing. we will see which one is true in the long term.

but it is bad because it is similar to bitcoin as far things like mining goes but yet different which makes things a bit complicated. for example BCC's fast difficulty change is creating a seesaw for miners to switch back and forth (theoretically) and it can cause issues. and we saw it once already.
