Bitcoin was always supposed to be digital cash. It even says so in the original white paper title.
Where did this myth start that we need to 'let this go'?
No one uses cash at starbucks. It's all phones, credit cards and debit cards. Try and buy a beer on a plane. They don't take cash. So saying it's like digital cash is a little outdated at this point. We're dealing with digital gold.
It is not true that no one uses cash in starbucks, in fact there are people who are using cash on starbucks, because not all people that go to Starbucks do have this credit card or debit card, here in our country, most of the people still prefer fiat to use in this kind of transaction rather than credit cards or debit cards. We are just using credits cards if it is really necessary like if we run out of fiat, and we don't have a choice but to use credit cards.
