I can't believe people are seriously arguing that we are still in the early adopter phase - what?? Someone who starts using a technology 5 years after it comes out is an "early adopter" ? Wtf do you call the first people who started mining with CPUs then? Prehistoric adopters?
Ok. Arguing without a point again.
To me early adopters = got in before GPUs and ASICs. Mid = Got in during GPU era. Late = Got in after asics came out and dominated mining.
And the ones that get in in a few years time when Bitcoin has reached mass adoption? What are they?
