It's probably more a case of when than if.

For me, the big question is whether we're out of the "wildly speculative" phase (where coins can triple overnight) and into the "new tech growth" stage where the market steadily increases 50-100% a year without too many insane swings back and forth. Like the NASDAQ between 1974 and 1999... from 275-ish to 5500-ish; 20-fold increase in 25 years.
