I suspect most people here will be in the Keynesian camp; folks heavily invested in Bitcoin probably aren't (specifically, most folks who tend to be heavily free-market/hardline capitalist tend to favor Austrian economics), but I would be surprised if that's the majority position. Other than a small bump in the 1970s, we've more or less been operating on Keynesian economic policy since FDR.

Inflation and deflation only really impact you when a) your wages get out of sync with cost-of-living prices, or b) you are borrowing or lending money (or just have cash sitting around that isn't being utilized in any fashion). If your wages and prices all fell to 1/10000th of what they are today, your purchasing power (in terms of hours worked per loaf of bread gained) would remain the same.

Deflation would harm your ability to (responsibly) take on debt. But, it's arguable that our current economies are so heavily debt-fueled because of our inflationary policies, as well, so it's worth keeping in mind as a variable when processing the concept that deflation = less borrowing. Deflation is scary to Keynesian economists because the Keynesian model only works when people aren't significantly saving anything beyond what they invest - that is, their money is all either spent on goods, or is loaned to other people. Holding money in an inflating economy is irrational since it is constantly losing purchasing power; thus, since it is in your best interest to spend your money as soon as you make it (either on goods and services, or by investing it somewhere that will offer a return greater than the rate of inflation), money keeps on rolling around in the economy.

The theory is that once people start socking away money in their mattresses, you get recession or depression. Deflation would encourage lending (either directly or through investment), but since it discourages borrowing, people may end up unable to find people to accept their money, and the economy grinds to a halt.
