There are a lot of people who really underestimate bitcoin in the beginning.
We just have to go back to 2017 bull run and then 2020 lowest low because of the pandemic. And then just one year, the price has growth exponentially to $60k ++ and still growing.
It people can't see the future in bitcoin, then I don't know what graphs and indicators or past historical logs will convince them to invest and look for the future.
(The lowest low happened by December 2018 and in March 2020 prices somehow held not to beat the 2018's low).
You are right that almost 90% of people are still not ready to understand the true potential of bitcoins. I may be understanding only up to 50% because honestly I was not expecting $60 by April month itself but I was expecting $100k by this December and by seeing the rate of current growth, I guess we may test even $400k levels by end of this year.
There are many articles and videos are available to understand potential of bitcoins but people never find time to go through them but they just want quicker profits and then they stay regretting for missing out life changing chances.
