Those who invested in bitcoin way back 2009 had not experienced any bull run before nor have much knowledge about the blockchain technology, yet they took the risk to invest. You and I have witnessed a bull run and heard about the numerous potentials of crypto so why do we still have to feel reluctant to invest in bitcoin. Let's be optimistic about our digital assets because its all we have.
I think its wrong saying the early investors of Bitcoin has no knowledge about the technology behind Bitcoin, I believe those are the really investors who did not only invest their funds but also invested their time knowing fully well what Blockchain technology will transform to in the nearest future.
Most people invest nowadays just to make huge profit and based on speculations with little or no idea about the technology.
Am still here because I have learnt a lesson from the early investors and lots more about blockchain technology based on research and other ideas gotten from this forum.
