That was the collapse of ETH, because most of the airdrop and bounty programs were through the ERC-20 platform. Do you think the same thing happened?
You should not be afraid or worried about the decline in ethereum prices, because Ethereum will one day grow again, even though to raise the price will require a process, and remain optimistic that you do not panic and sell your Ethereum now, for example you have it, keep it and keep it as good as possible until the price will rise again.
