Probably because people are looking primarily for the most convenient for them methods of transferring money.
Credit cards, forwarding between bank accounts and so on are much more convenient, because these funds can be paid in all stores and medical centers.
While bitcoin and cryptocurrency are not accepted everywhere.
so what is your answer on here . covid-19 increased btc adoption or not ? looks like your answer is not .
its not true that btc isnt accepted anywhere but btc were now legally accepted on many places though btc isnt really that convinient . for me i think that the covid-19 somehow help btc adoption because many people surely looking for alternative currency next to fiats and prolly people already notice btc but i think not all wil consider using btc but that is stll okay atleast people are now aware that there is btc existed online .
The fact that bitcoin exists and can be used by most people was aware back in 2017.
Of course, some services accept Bitcoin, but their units are not located in all countries.
In addition, the high level of volatility casts doubt on Bitcoin as an asset for storing its funds instead of fiat, as a result, people will tend to buy more American Dollars than BTC.
