During contract development, we encounter many demands for pledge mining, such as single-coin pledge, dual-coin pledge, computing power mining, etc. Most of these demands are based on how many coins are produced per second (how many coins are produced per block). According to the pledged Quantity-weighted equal shares of coins produced. A centralized program can easily fulfill this requirement, but without a timer on the blockchain, a large number of cycles cannot be achieved.
Leveraged trading is a trading method that uses borrowed funds to increase the size of an investment position. Investors can magnify their investment profits through leveraged trading, but it is also accompanied by higher risks, because losses will also be magnified in the same proportion. Here are some key concepts about leveraged trading:
Leverage ratio: Leverage ratio refers to the ratio of investors’ borrowed funds to their own invested funds. For example, if investors use 2x leverage, they can control a position twice the amount of their actual investment. Common leverage multiples include 2 times, 5 times, 10 times, etc., or even higher.
Margin: Investors are required to pay a certain percentage of margin when trading with leverage, which is part of their own investment. The size of the margin depends on the leverage ratio, usually expressed as a percentage. Higher leverage means lower margin needs to be paid.
Profit and loss amplification: A distinctive feature of leverage trading is that both profits and losses are amplified when the market fluctuates. If the market moves in the direction investors expect, they can make greater profits. However, if the market moves in the opposite direction, losses will increase accordingly.
