No, no, because when you use an ATM card what happens behind the scenes is that your crypto gets sold for dollars and the merchant receives dollars. In essence if you spend crypto this way, you are 'selling' your crypto just as if you were selling it on the open market.

The only way to keep crypto within the system is to find merchants who allow payment in crypto but which will actually hold that crypto instead of cash it out for fiat. We're still some ways off from that point.. We may get there sooner if we do spend the bitcoins first, to get merchants used to the idea.
