It's not news that Bitcoin was cheaper back in the day and it's also not news that there were users that trusted it when there was no historical value to go with and acquired a large amount of it to get them their dream life.
Only a handful of people think that Bitcoin will boom and many have doubts about BTC during that early stage but BTC proves these doubters wrong though.
Would we see any such ROI in the coming ten or twenty years, most probably no. No asset increases exponentially, it gets to a point when it starts slowing down and stabilizing, we are very close the actual valuation of a single bitcoin.
I still believe that we are still far away from the actual valuation of a single bitcoin. One of the reasons is the percentage of Bitcoin adoption and the people who are still hessitant of using it. Aside from that. we can still see that numerous countries that are still half-hearted and is not somehow convinced about the use of Bitcoin. Since we believe that Bitcoin will be globally accepted, the current adoption percentage simply tells us that Bitcoin is still far from its supposed to be value.
It's great the poster is anonymous, privacy is very important and we would not want the wave of interview requests and attention that would follow his exposure.
Whether we wanted it or not I believe being a guest poster removes the possibilities of identifying the person.
