So just learning about Bitcore.  So in order to participate in the airdrop, I have to sign the message AIRDROP in my BTX Wallet.  That requires me to download the entire BTX blockchain correct before I can sign the message?  Right now the client says it will take me 13 weeks to download the blockchain.  Do I have to download the entire blockchain to sign the message?  If I do, is there a place where I can download an up to date copy of the blockchain to speed up this process?  Thanks guys!
