I don't understand why we are forced to give out our private key of our wallet in order to claim bitcore. There are many other airdrops with no such requirement.
You can CLAIM your coins from an emptied BTC wallet, as you did for the other forked coins. If you know other forks, no explanation needed. Its the same idea regarding your security.
Then its the weekly AIRDROPS.
No privkey involved. You are only asked to register your BTX address and have >1 BTX.
Claiming and
airdrops are two different methods to freely distribute the coins. Maybe our webpage its not clear enought about that. That will hopefully change soon.
