Hello guys, could you please tell me how much cash is enough for basic needs? Mobile payment in America is not as convenient as that in China, right? In China, you can travel all over the country with zero cash ?

The United States is also mostly cashless, but they use credit cards. It's always good to carry some cash just in case.

Suggestion: Use cash for refueling. 500 dollars should be enough.

300 should be enough for the trip.

Mobile phone payments are not common in the US, but credit cards are everywhere!
