You are right on this, but you need to know that when bitcoin got released on 2009, no one took it seriously,
i mean, most people who had bitcoin during those times were using this one to send tips, or to send "memes"
in form of money, because bitcoin was an useless thing by those times.
Do you remember the pizza guy? He bought it with bitcoins because he earned them for free, he didn't knew that each bitcoin would be worth $19,500 by today.
Bitcoin entered the arena claiming to be the next big thing in electronic cash. It took a while, but it gained traction with more and more enthusiasts convinced that it would be just that.
Bitcoin has increased, but not for the money, the whole community is increasing, not just the "value" in us dollars.
