Bitcoin can be seen as a currency or as a mere store of value, right now is the latter that seems to be the preferred option. Bitcoin is banned only in a few countries, mostly autocratic regimes and even there is not working. But in the rest of the world, it's been regulated in one way or another. Mostly it is considered property and not a currency, just like stocks or gold.

The fact that only 2% have a BTC wallet tells us we are still very early and the potential for growth is huge. In 1997 only 2% of people have an internet connection.

Can you explain to me in fine detail how the TCP/IP, SMTP, or FTP protocols work? No? Well, we are using them right now to browse the web and to communicate.

My point is, people need a safe haven against inflation and infinite money printing and Bitcoin clearly provides the best we've ever seen. Those who want to know more can go down the rabbit hole and learn all the intricacies of this new asset class, most will just buy and HODL.
