I think people who missed out on the chance to make money is still sour about the fact that they couldn't make it in at the right time and that is the reason why people keep making topics like this. Yes bitcoin became 8 thousand dollars from zero in 10 years and yes its not a hyip or ponzi because it is literally a market where people decide what the price is.
A ponzi is something you give money and the central institution not having enough so paying everyone with others money and eventually running out of enough money to pay people which is unsustainable and can't be run for too long, hyip is about the same but that is when you increase the price to just keep paying people back. Bitcoin and its technology is open to public and you can check that its neither of those things, its a digital currency people are willing to pay premium for and that is it.
Yeah, I could have been one of them sour grapes as well in 2016 -- I actually had the opportunity to come into it in 2013 when I first heard about it, or even in 2014 when I first turned down someone who was trying to convince me it wasn't what I thought it was (yet another in a long line of failed digital currencies). My context was a decade earlier of getting really effed up by e-gold's spectacular demise and I didn't want to get bitten again.
But I did myself the favour of trying to approach Bitcoin objectively in that late period (2016). And good thing for me, I was convinced in a few weeks, and half a year later after patiently learning and using, created a new account here, having forgotten the first. And then a steady rate of participation later, I'm here today.
Maybe I'm foolish and low IQ. I wouldn't know. I'd like to think I'm at least on par with OP on those terms.
