The value of stablecoins is usually pegged to the US dollar 1:1, but it will fluctuate slightly due to factors such as market supply and demand, investor confidence and reserve assets. For example, USDT fell to $0.87 in 2018, and USDC fell to around $0.87 in 2023 due to the Silicon Valley banking crisis. The anchoring mechanism of stablecoins mainly includes: 1. fiat currency reserve type (such as USDT, USDC), which relies on the issuer's reserves; 2. cryptocurrency mortgage type (such as DAI), which maintains stability by over-collateralizing other cryptocurrencies; 3. Algorithmic stablecoins (such as UST), which relies on algorithms to adjust supply, but have higher risks. Common trading platforms recommendations include: 1. Binance, providing rich trading products and strong liquidity; 2. OKX,

USDC is safe. It is jointly issued by Circle and Coinbase. It is regulated by the US FinCEN. Its reserve assets are US dollar cash and US bonds. It is regularly audited independently, with high transparency. 1. USDC has strong compliance and is strictly regulated by the United States; 2. The reserve asset structure is clear, supported by cash and Treasury bonds; 3. The audit frequency is high and transparent; 4. It is widely accepted by institutions in many countries and is suitable for scenarios such as DeFi and compliant payments. In comparison, USDT is issued by Tether, with an offshore registration location, insufficient early disclosure, and reserves with low liquidity assets such as commercial paper. Although the circulation volume is large, the regulatory recognition is slightly low, and it is suitable for users who pay attention to liquidity. Both have their own advantages, and the choice should be determined based on the purpose and preferences of use.

The altcoin transfer fee varies from chain to chain and is mainly determined by the basic network fee, transaction speed and Gas unit. 1. The Ethereum fee is high, with an average of US$2~20 per transaction, suitable for high-value transactions; 2. The Binance Smart Chain fee is low, about US$0.1~0.3, suitable for daily operations; 3. The Solana fee is extremely low, usually below US$0.0001, suitable for high-frequency transactions; 4. The Polygon fee is less than US$0.01, compatible with EVM; 5. TRON focuses on low-cost, and the handling fee is almost negligible. Users should reasonably choose the transfer method based on the characteristics of the chain, network congestion and gas fluctuations, and at the same time confirm that the token belongs to the same link as the receiver to avoid asset losses.
