We all knew that .io domains selling really well in the past few months.
I/O stands for input/ output, it's a term of communication process between computer hardwares. It had nothing to do with CryptoCurrency.
However, industry players and registry make a great effort to promote .io bind to something high-tech & computer related. Somehow all of the sudden people start to believe .io had a strong connection with cryptocurrency & blockchain and therefore the price go up like a rocket..
It's a fascinating example of how a successful marketing make such a big different.
IMO, I believed .CC can be an Abbreviation for 'Crypto Currency'. and it will be the next honeypot.
