most of the airdrops are too small to even dump

you have to try to dump them though, because it will just lose its value.
there are exceptions where they gain real value for a short time but it is risky to hold them for long.
Yes but I think ethd is making news now in airdrop world. As i can see it the value is increasing everyday that's why I'm disappointed with myself as I sold it as soon as I got it. Maybe I'm just thinking that over time it might lose its value. But what's done is done and I'm thankful that I received ethd and make some money.
So OP it's all up to you to decide whether you trust and hold or you dump it.
