Dave - thanks for this. Yes - I am in the U.S. Not quite sure if I follow you. It's been my understanding that "Balance Transfer" is a "Card-to-Card" transaction and is a cashless transaction. Just the transferring of debt from one card to another, and cash never enters the picture. Tell me more.

Also, I've already checked with the 3 companies you mentioned directly (Citibank, BoA, Chase; customer service over the phone), and all 3 were adamant that they don't allow the purchase of BTC with their Credit Cards. Thanks....

I'm seeing promos from Credit Card companies for 0% APR for 12, 15, or 18 months. My plan is to buy a miner from a turn-key company and install it at their facility and pay off the miner in approx 9 months from mining proceeds (please - no sermons on the perils of doing this; I've run the numbers and am willing to take the risk). They require payment by BTC only, which would require me to buy the BTC with the Credit Card. All the credit card companies I've talked to so far don't allow the purchase of BTC with their cards.

Question: can anyone recommend a Credit Card company that 1) is offering a 0% promo of at least 12 months and 2) permits the purchase of BTC.

Thanks in advance....
