If the price increases from 30,000 USDT to 36,000 USDT:
- Unrealized P&L: 0.1 BTC * (36,000 – 30,000) USDT = 600 USDT
- Remaining Margin: Initial Margin + Unrealized P&L = 300 USDT + 600 USDT = 900 USDT
Despite the perpetual swap price increasing by 20%, the margin grows by 200%.
If the price of BTCUSDT increases, it means the value of Bitcoin rises, which can lead to greater profits for holders, attract more investors, and potentially drive up the prices of other cryptocurrencies as well. It can also create more trading opportunities and increase media attention on the market.
