This is a discussion on Problem depositing with Circle, did they change? within the online poker forums, in the Poker Deposits & Withdrawals section; I've been depositing for the past year using bitcoin with the following method
Circle----> Blockchain-----> ACR
Yesterday when I bought coins off Circle and went to send
I don't think that Circle is selling Bitcoin anymore. You can still buy coins from Coinbase, cex.io (I think?), and localbitcoins. Be aware that the IRS is trying to subpoena Coinbase into giving them all of their customers' information if you don't want the government up in your business. I can't imagine that the IRS won't target other major exchanges in the future, though.
