When BTC captures an industry, it doesn't really matter what it is, when it dominates any industry as THE way to trade, value will skyrocket. That skyrocket will self-perpetuate another cycle of boom and bust, but the settling point will be far higher than today's prices. When we go from 1% of people owning bitcoin to 5% it will be a major move in price, easily to $100k and beyond.

When you think about the volume of money that moves around, and BTC is going to have to account for a substantial portion of that flow, $500k is not at all unrealistic and it will be here before we know it.
