It seems to me that it is not a property of bitcoin or cryptocurrency itself that is allowing these folks to supplement their income with "manual" labor. Instead it feels like the fact that it's a new, relatively unexploited market that is enabling these ventures to scrape together the people and resources necessary by using extremely thin margins. I can't imagine this will be viable for long as more people get into it.<p>Sure, you can provide clicks in exchange for bitcoin, and that might help some homeless people right now. But what happens when that becomes over-saturated and/or youtube et. al. get better at preventing that? Amazon Turk + BTC could be viable.<p>> This is the only property for which Dale is currently accepting digital currency, but so far, he says, “it’s been a good experience because bitcoins have gone up in value, so it’s more than I would have gotten in regular dollars.”<p>I bet he won't be so happy when the price swings in the other direction. Therein lies the eternal problem with BTC for trade on a scale even beginning to approach that of what goes on in the world today.
