You are kidding right? All that matters to anyone that gets paid in bitcoin is the value of the bitcoin at the time they were paid and the value of bitcoin now (or when they exchanged it for fiat or goods if they have already done so). Someone that is trying to make a living is not going to care about any kind of average
False Dichotomy as I get payments in multiple forms of fiat and BTC thus I can always leverage BTc's volatility to make any purchase I make cheaper.
Anyone that gets paid in 100% BTC should instantly convert some of their salary into a more stable currency.
Bitcoin isn't perfect and one should leverage its strengths to ones advantage. I.E.... I just made a multiple holiday purchases at amazon for 15 % discount with BTC with Purse.io and those coins were purchased @ 110 usd so my discount was much greater.
Obviously, if you are scraping by and living paycheck to paycheck you don't have this flexibility and thus should start saving to empower oneself.
