The ATM withdrawal machines are always busy where I am, so people still are using cash for something. But I am encountering quite a few businesses (mainly sports venues and intermediate type quick serve restaurants and parking facilities) that accept nothing but debit and credit. But I think cash will be around for a while, especially US 20s and US 100s, which are unbelievably popular outside the US. If you just judged from inside the US, you would think the most popular note were 20s, but in actual fact there are way more 100s than dollar bills or 20s world wide. The demand for cash 100s ain’t going away too soon, given all the instability in the world.
US dollars are more popular than gold at present. Gold takes a while to liquidate.
