I found a project offering an airdrop but required participants to download and install their mobile app. The app is newly made with only few hundreds download and I don't think I'll ever use it.
Is it too risky?
For me, if airdrop does not go in line with the way that is already known or makes it simple but rather starts introducing new and difficult parts to it, I just drop the idea. After the whole thing, it might not be a guarantee the coin will do well.
