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?
If that airdrop is worthy enough i might consider installing any apps but using only a different phone or emulator as what
blackmagical said. But if that apps ask you something after you installed it before you will get your airdrop i think you know what it is. Be curious all the time and think wisely, in times like these only few are real left.
