They did more, now they have more. Why should they be ashamed?
What they did was being lucky (right place right time.) Effort isn't in direct correlation with being a Bitcoin millonaire by any means, let's be honest for a second there. This doesn't really mean they do not deserve this. In economic schemes the ones that are there first get most of the cake, unfortunately this will always be like this as long as currencies are needed for societies to function.
But it is important to note that the people who were here, in say 2011, were not rich that was not a "thing" in the world of bitcoin. All this nonsense about "investors" came later. Many of us did not give a crap about money. This was about securing our financial rights and opening opportunities outside of traditional banking.
For me it still is. I do not want dollar, and I do nothing to get more dollars. I want bitcoin so I can buy stuff with bitcoin. Now that's just me, others may want to use bitcoin to get more fiat.
Back then we were laughed at for spending $500 to buy 500BTC. Now people say how unfair it is that we did it. The same may happen to you if bitcoin reaches $10K.
Old timers are visionary who work for the benefit of mankind. No wonder many disappeared without a trace after bitcoin gains momentum.
