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?
There's no guarantees that bitcoin is going to reach x amount of dollars or mass adoption. If bitcoin never rises above the current ATH then people buying recently are late adopters. If it does then I guess we could call the first generation of adopters 'pioneers', anyone buying under $1000 an 'early' adopter, and others can be the 'late-comers'
