At least here I can buy and sell anytime at any price! The exchange rate is off by 0.2 and it still doesn't match the price anywhere! Playing through has already revealed that the Vietnamese exchange rate is a scam.

$BTC coin is just a scam, the stock market is the legitimate one, stocks see coins as a little brat who specializes in lurking and pumping without having anything sustainable. Besides the top coins, just look at the unlimited supply, the price divided by 5 or 10 times, so this is just gambling.
