A "pair of pairs" in the context of Binance refers to two specific combinations of cryptocurrencies that can be exchanged with each other on the Binance trading platform. Here is a brief explanation of how trading pairs work on Binance:
Trading Pairs: A trading pair is a combination of two cryptocurrencies where one currency is exchanged for the other. For example, BTC/USDT means you can exchange Bitcoin (BTC) for Tether (USDT), a stablecoin whose value is linked to the US dollar.
Diversity of Pairs: Binance offers a wide range of trading pairs, both on its spot platform and in futures. The most common pairs include those with popular cryptocurrencies like Bitcoin (BTC), Ethereum (ETH), and various stablecoins like USDT, BUSD, or USDC.
Volume and Liquidity: Pairs vary in terms of trading volume and liquidity. A pair with high liquidity allows large orders to be executed without significantly affecting the market price. Examples like BTC/USDT or ETH/USDT usually have high liquidity.
Pair Selection: The choice of trading pair depends on several factors, including trading intentions (speculation, investment, hedging), the associated fee, and the availability of the cryptocurrency you wish to acquire or sell.
Removal and Addition of Pairs: Binance periodically reviews its pair listings and may add or remove pairs based on liquidity, trading volume, and other factors to ensure market quality. For example, in October 2024, Binance announced the removal of some pairs like ALGO/FDUSD, CHR/ETH, DGB/BTC, and GMX/BTC.

Futures and Margin: In addition to spot trading pairs, Binance offers futures contracts and margin trading, allowing users to speculate on the future price of cryptocurrencies or increase their market exposure with leverage.
Commissions: Trading commissions can vary depending on the pair and the user's VIP level. Binance has a tiered fee system, where regular users pay a 0.10% transaction fee in the spot market but can benefit from temporary promotions or reduced fees on certain pairs.

If you are looking for more specific information about which pairs are currently available or are interested in the trading details of certain pairs, I would recommend visiting the official Binance website or checking their recent announcements on their blog or through their official communication channels.
