My thought concerning early investors who adopted bitcoin it’s certain they knew bitcoin is valuable before investing and for those who left investing so early that’s their lose, some features might have attracted early investors but I can’t tell accurately if they knew the growth will be this massive. This is accurate, I can’t compare bitcoin with other coins or product due to value, one must be careful so they don’t get fooled with advertising or promising project, if people invested in bitcoin because of adverts I’m sure bitcoin adopters will be so few because bitcoin doesn’t need such activity.
I doubt that majority of the early bitcoin investors knew that bitcoin will be valued to this extent because if they were aware about the future growth of bitcoin many of them could have invested their fortunes in it. Though i am not generalizing all the early investors because there were some people that also saw that bitcoin can increase in the future and they invested with their discretionary income while having the knowledge that despite that they believed in the future growth of bitcoin, unforeseen circumstances can still occur.
We have already said it often times that bitcoin is a potential coin that needs no publication, announcement or advertisement because it is a self made marketable asset, it only needs growth and the news is all over the internet already of which a large number of the world population are making use of the internet so they will definitely come across news about bitcoin and it's potential growths over the years. When the price of bitcoin got to $100k, the news and excitement was all over the internet so tell me who will hear about it and not develop interests to invest in it.
