You can win 99 times with 3 or 5 dollars, but as long as you lose once, you will lose 300 or 500 dollars.

$WCT want to win my money? No way, will I lose to you? Unfortunately, I can only upload four pictures. You plummeted all the way, while I went long. It's a pity, I haven't lost once. Hahaha. Let's see if the opening time and the selling time exceed a minute? I don't seek to win much, just stability.
