Distribution for BTX Holders
Every registered bitcore holder with a wallet loaded with a minimum of 1 BTX gets
a weekly 4% airdrop, increasing with 1% every month!
Nitpicking aside, but it is increasing 1 percentage point, not a measly percent. For example, going from 4% to 5% would be more like (5-4)/4*100=25% increase.
Just letting you know.
Will paper wallet work for airdrop?
It definitely will. Coins are saved on the blockchain, not in your wallet, either paper or otherwise. Your software wallet is only a tool for creating and signing transactions with your private key. You just need to sign up your address for the airdrop. Don't forget to do that!
