Wait a moment, wasn't Bitcoin meant to be digital version of gold?
Well, credit/debit cards are something absolute opposite to gold, they are "bad money" from Gresham's law:

Bad money drives out good

So by using BTC CC you basically do that, you allow them to accumulate "good money".

Of course one can appreciate this solution as easy & convenient - but please be responsible and only spend what you can re-buy in near future or you'll be crying as I'am :cry:
