I have significant doubts about these projects, the foremost being the identities of the people conducting them. I've only seriously examined eXRP so far, and although they have a very large Telegram group, the devs don't seem active and I almost feel like the size of the group is a way to hide that fact. I don't know enough about the others (eDASH, eBTC, eLTC) but I would tread cautiously.
So what's the worst that can happen, you have worthless tokens sitting on your ETH address if you signup for these airdrops?
the losers are poor people getting 50 $ in order to invest in this money and then they got nothing cause it's scam this what i mean !! cause those who get airdrops they dont care but the promote this coin also
