.info is a $1.99 a year expense, I'm guessing they are on a shared server which could be under $9 a month. Not allot of people use Bitcoins so server traffic is probably low atm. I have unlimited bandwidth on a shared account for $100 a year. I'm assuming they have something similar
As far as I know blockchain.info and bitcointalk.org is work for bitcoin support freely,
And my question is ,who own it ,and who pay for it ?
Running a site like Blockchain is really expensive.
