I once had an airdrop coin that was worth $100 dollars a week before but the value dropped to about $1.5 three weeks later.
Same, I also had tokens that have just literally "died' on my watch (in my wallet), but the difference is they were airdrop/bounty tokens, that we haven't invested in, so when it comes to selling them, the only question is how much we value our time and efforts, and in your case it was just an airdrop, which means that you've spent around 5 mins to get it. But the OP invested his money in his tokens, so it would be useless (profitless actually) to sell now.
