TLDR:
. Some people here need to read up on history that isn't from the point of views of government sponsored/regulated schools and texbooks ( seriously, they lie to your face )
. In an unregulated and deflationary economy employers couldn't drop the wages so low that people would be forced to work for longer without consequences to them personally, that and the limited nature of deflationary currencies wouldn't allow for it mathematics wise
I guess you have less trust in economics textbooks (and wikipedia) than I do. or pehaps you have a significant level of distrust that you are biased toward ideas that conflict with such textbooks. to each their own. I suppose the recent macroeconomic instability has contributed toward your distrust, but in my view that is somewhat short term reactionary
are you talking about real or nominal wage? if BTC can buy 2 apples instead of one. your employer will pay you half the BTC after deflation. in the end he's still paying you one apple. The important caveat is why would he buy your labor anyway if hoarding his BTC can give him/her a better return? it's not a switch, but this effect starts small, then snowballs
