Satoshi's invention is an electronic system. Nowadays, however, you can easily notice how the emphasis on "electronic" is omitted.
I don't think bitcoin is an electronic system...
Well, I meant electronic cash system.
That is, mass adoption, when the purchase of a cup of coffee or ice cream can be paid for bitcoin, is this not the goal we should strive for now?
I believe the success of adoption is when every person is transacting with Bitcoin by paying for their goods in supermarkets, stores, and malls via electronic transfer regardless if it is face-to-face or not.
I don't think it is. Again, Bitcoin is kind of superfluous in a face to face transaction if you have the option to use cash. The cash system provides you instant, anonymous, and peer-to-peer payment system. But if you've got no option, then Bitcoin is the way to go.
But Satoshi clearly designed it with "online payments" in mind.
How so? What design choices would have been different if Bitcoin was more of a real life electronic payment method? 1 minute confirmation time? I think Satoshi had other reasons to choose 10 minutes, like ensuring stability of the network.
The very first sentence of the whitepaper goes: "A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution"
Electronic money is both the money of the Internet and the money for real life spending because physical commerce is digitalized, so Bitcoin shouldn't try to focus only on the Internet.
For as long as cash is still around, I guess cash is the better payment option in face to face transactions. When the time comes that cash system dies and is replaced with a CBDC or other digital ways, then indeed Bitcoin, as an electronic cash system, will replace it as the best option.
