user124543: I have observed that the prices will be different, can I earn the difference?

user119852: This is called arbitrage.  It is theoretically possible to make money this way.  Whether it is practically possible is another question.
There was a feature of the market known as the 'Kimchi Premium', where it looked like this should have been possible with South Korean markets.  However the capital controls and other regulations made this difficult or impossible to exploit.  It is possible you are missing some forex complexity.
