you are full of shit. 1) coinbase is not sending anything to IRS and never has. A linkedin to some accountant, wtf? They may or may not in the future, long way off, but that's not what you said initially. 2) read your own link, the guy couldn't get his bank account verified that's why coinbase decided not to send him the bitcoins and refunded him. Read all the replies after that stating coinbase always honored their transactions. I bought with coinbase for much larger than 10 bitcoins and have the price gone up 50% in a day without any issues from them. And for such a "common complaint" all you can find is 1 bullshit link? All you doing is spreading rumor and false info on probably one of the very few reliable sites that's ran professionally. So i say again, you are full of shit.
I'm not arguing with you. You have obviously never thought through the issues and may not even be aware or able to comprehend the issues. To argue with you is a waste of time.
