The variability or volatility is exactly why the realization of the % shared is driven by the customer or in this case the resident... they lock it in when they feel the value is right for them...as for the downside risk. Yes that is all on me as the business owner...but in an ever increasing clown world...my ability to attract and retain residents who are "bitcoiners" is going to allow me stand out above my competition and keep my business running. Those who produce value in BTC terms will more likely be the more stable or less volatile over time....
