Hi,
we bought domain
http://centralizedcoins.com/ for our cryptocurrency project. But at the end we went with another domain.
This domain have two meanings:
- centralized coins at one place (eg. price tracker of all coins on at one place)
- opposite of decentralized cryptocurrency (eg. private blockchains, banks blockchains, which are not public etc.)
More information is at domain itself. Contact in WHOIS or here.
