So, I was talking to a coworker who is a CPA and he told me that any gains made in bitcoin and then transferred to a sportsbook will be subject to income tax. Is this true? How can I figure out my cost basis? Does Coinbase keep up with it? Ive also got money in a wallet and at poloniex as well. I've been buying bitcoin for over a year now. I even took a shot in the dark at ethereum and litecoin in early June. Just want to make sure I don't get hit with some penalty by the IRS when it comes to income taxes in April.
Thanks in advance for any more info.
