This is a creative domain name for a blockchain business or consultant. It also suits any other application involving actual or virtual blocks, anything from planning to toys.
The .co extension has found wide use around the globe as an alternative to .com. This site highlights case studies of companies using .co domain names from around the globe.
The .co extension is highly respected and valued. In the past three years there have been more than 1600 domains sales in the .co extension, with an average price of just under $1700.
The domain name is currently registered at Epik, and they act as a third party holding payment until the domain name is complete, so you can have full trust in the transaction.
I look forward to seeing someone put this memorable domain name into active use.
