I can not register at
https://x-cash.org.
At registration produces an error: An error has occurred.
Like everything is just a name, mail, twice the password.
Changing mail does not help.
What could be the reason?
If you are signing up using proxy or VPN they will block your registration, My suggestion is use your normal internet connection in the airdrop registration. Proxy and VPN's are already block by their server.
