<prompt> Human: Hi, I read an article about gain more points or rewards from credit cards by buying dollar coins and using those same coins to repay the debt. I really dont understand how you buy coins and is the a UK equivalent to this?Hobbyists rely on having dozens of credit cards to allow rewards binges one technique involves buying dollar coins on a credit card, then paying off the debt with the coins purchased, but keeping the cards rewards.  <response>: Its all but impossible to do anymore, sadly. Unless you can find a merchant willing to work with you, its a bitch to do without actually costing you more money then the points are worth.
