doubt it, what's the point of only partially repaying off your credit card at all. they'll just make minimum payments and wait it out. only mgio here sounds like he wants to sell at a neverending loss 
So you are betting on BTC increasing fast enough to outweigh the 20%+ interest being charged for not paying off the balance?
20% (kind of high- most credit cards should be less unless you have terrible history) YEARLY interest... 100% yes
Some aren't borrowing money- and only 4% yearly interest if a equity line was used
anyways, bitcoin's value keeps rising at a pace that is much higher than credit cards charge. you are better off waiting and betting on the trend of 4 years then paying it all off at a loss regardless. it's really really common sense
