Some more info on the Midnight airdrop for the Bitcoin holders out there. Going off the estimated supply and the valuation that is being talked about, I think this will end up being an airdrop of about $300 per BTC.
Bitcoin is the worst $ for $ of any coin to receive this airdrop, but free money is free money.

what can you expect from shitcoiners....
however, 300$ can be pretty nice, if you have many coins. Surely many will move their coins to a new address for that... (which everyone should do after signing messages!!)
...
So, to claim, I have to sign a message using the wallet.
Any security concerns about this?
As long as you move your coins and use TOR when showing them your signature it should be fine. You can use a VPN but then the VPN provider will know who you are
