Yeah, i don't think anytime is late to start buying or using BTC, but recent adopters usually look back and wish they had bought earlier. I often tell people to put that thought behind them, even some of these early adopters sold their coins a long time ago, so who is to say you wouldn't have sold yours if you were an early adopter.
I agree, BTC is not a money making scheme and whatever comes out of ones investment in BTC, they should feel great to just be part of this network and have the knowlede of this censorship resistant money.
