I'm basing it on eight years of experience in Bitcoin.
"Bitcoin for coffee" and the like is a waste of the tech, imo. Buying network services such as you described is a better use as intercountry payments with debit cards isn't always feasible.
Bitcoin's use is better as a transnational currency when traditional payment channels are cumbersome. To be frank, Bitcoin still has some work to do in the payment channel dept but Lightning Network is getting there.
In the US, there are more than a few places where you can trade out btc for gold/silver and sell the metal for fiat. It's preferable to selling on an exchange, imo.
If you can't spend now, hang onto your btc until you can. Saving is always a good idea.
Of course only small communities have a majority of btc. Too many people - geeks included - spent too many years believing the fud being broadcast about Bitcoin while others were collecting btc. I've seen the blistering scorn from some here on HN over the years.
When I first ran across Bitcoin in 2010, I thought it was a scam but was intrigued by the tech. After studying it for about a month, I realised it wasn't a scam (though scamsters abound in cryptocurrencies, as in all things money) and went around to my friends in the tech community in my city to show it to them. They know me to be literate in networks and cryptography but only one person in the ten or twelve I approached was equally interested. The rest poopooed Bitcoin, some outright laughing me out of their offices.
Institutional thinking is what kept a lot of smart people from even looking at Bitcoin early on. The findings in this study shouldn't be surprising. In five years, should the internet still be functioning, Bitcoin will be more spread out than it is now.
I'm a child of the 60s/early 70s who grew up watching Fred Rogers. My environment was hell as a child. His show was a small counterbalance. Every little bit helps.
Objectively, Western corporate-military ideology has been far deadlier in Asia and Africa than religious fundamentalism. The US has attacked far more countries and killed more civilians than religious extremists have.
The system is working as designed: shield state actors from liability while increasing police powers.
A few lose their jobs or get fined, but fewer go to jail or have to account for their excesses. I really question the motives of anyone who wants to be a cop in this environment.
