Hi @duongtd1102,
It seems like website static cache exists at your end.
Are you using any cache plugin?
Our plugin updates coins Price data within 10 minutes. And our other users never face this type of issue. Here you can track coins price data changes timing.

Please just disable cache plugin or purge all static cache and check it again.
It will work fine.
