In the cryptocurrency world, if each project is viewed as a small country, then the tokens they issue are their fiat currencies, and the exchange rates between these tokens constitute the overall currency exchange rates. However, in the early stages of blockchain, things were simpler with fewer projects and clearer exchange rates for each trading pair. Later, with the consensus around Bitcoin gathering momentum and numerous projects springing up like mushrooms, a significant amount of capital was diluted, leading to a complicated web of exchanges between various project tokens, some of which have very low values. This has widened the development gap between projects. To facilitate the measurement of value, a few foundational tokens emerged: Bitcoin, Ethereum, Solana, and the stablecoin USDT, thus unifying the measurement standards in the cryptocurrency world.
