Also, can we sign with many BTC addresses for the same semux address?
Thanks. Seems a nice project (wallet syncing at the moment)

For the BTC airdrop there's no field for the BTC signature in the form, how are you going to verify the signature and see the balance?

I just registered, but didn't save my signature. The message displayed is now different so I can't sign it again and see the signature. Will I be able to claim BTR?
