How do we educate people that Bitcoin is a continuously growing global currency that is still in its early staged and each big boom and crash is just its early growing pains?
You don't really need to educate anyone, people will see it for themselves. Bitcoin has been proclaimed dead hundreds of times, every bear market is being called "a crash" as if it was a big deal, and yet Bitcoin is still strong and still growing. Each day someone new decides to invest in Bitcoin for long term, and that's already a good result.
Well, Bitcoin isn't "growing" in the sense of the amount of available supply since mining is completed. Is it "growing" in any other way? Is there any evidence (and any way to tell) if the number of individual holders have increased? Is there a way to show, in terms of hard numbers, that Bitcoin is "growing" besides it's price, which can go down as well as up?
