CPD Token is going to be an ERC20 token. At genesis distribution, it will be sent to the Ethereum address, which you are using at registration.
CPD Token will be airdropped to BTC holders at Bitcoin Block #629999. Only registered Bitcoin addresses will be eligible for this airdrop.
No. Only legacy Bitcoin address (P2PKH), i.e. an address starting with 1, is allowed to be registered for CPD Token airdrop.
To sign a message manually, you need to have private key of the concerned Bitcoin address. With your private key, you can use this tool offline. Otherwise, if your wallet supports signing message with Bitcoin address, you may use that as well. You may find this thread on BitcoinTalk to be handy to sign message using various wallets.
If you have used this tool, it would return something like the following.
-----BEGIN BITCOIN SIGNED MESSAGE-----
This is an example of a signed message.
-----END BITCOIN SIGNED MESSAGE-----

Yes. After airdrop to BTC holders, CPD Token will be auctioned off against ETH.
Auction will start as soon as the claim process for airdrop is over, i.e. on June 1, 2020. Total amount of CPD Token, that will be auctioned off, can be determined only after the claim process for airdrop is over. Amount of CPD Token, being auctioned off, will be half at the end of every month. Auction will continue till December 31, 2020. There will be 7 months of auction, where at each month CPD Token, being auctioned, will be half of the last month.
Genesis distribution will take place on January 3, 2021, the same day when Genesis transaction took place on Bitcoin Blockchain 12 years ago.
You will get 10% of whoever you refer. If the person you referred got CPD Token through airdrop, you will get 10% of that. If the person you referred invest ETH to participate in auction, you will get 10% of that as well.
At Bitcoin Block #629999, the total amount of BTC in circulation will be less than 90% of total supply, i.e. 21 million. Hence, paying 10% referral will never be an issue.
