#哥伦比亚VS葡萄牙 doge opened a short position and made three points. Finally, I can make some money too. I recall losing dozens of USDT on spot grid trading before, so I'll never do spot grid trading again. For long and short positions, I only use experience coupons, never with real funds. Gate also gave me coins. The experience coupon's time is a bit short, only three days. The profits from long and short positions are truly huge. No wonder so many people are willing to get into it. Sometimes I can't help but want to go in myself.
