In the crypto world over the past few years, 'liquidity' has become a buzzword. A sluggish market, delayed bull runs, altcoins not rising or even dropping—these are often blamed on a lack of liquidity. So, what exactly is liquidity? Simply put, it refers to the ease and speed with which an asset can be converted into cash. It's like when you make money: some goes into your wallet for immediate use, while some is locked in fixed deposits that need to be withdrawn before use. The former has high liquidity, while the latter has low liquidity. Liquidity can be broken down into MO, M1, M2, etc., with M2 being a key indicator of economic activity. It reflects the liquidity of the money market and the level of economic activity. Actions like increasing the money supply, the return of investment funds, or the conversion of fiscal deposits can all boost M2 levels, making the money supply more abundant and the economy more dynamic. The crypto world is closely tied to liquidity. In 2020, the Federal Reserve responded to the pandemic with rapid rate cuts and quantitative easing, triggering a massive bull run in crypto. In 2022, as liquidity decreased and the Fed raised rates, the crypto market entered a bear phase. Now, with the Fed likely to cut rates twice this year, the direction of liquidity remains uncertain. Whether the bear market has truly arrived will be left to the market and time to reveal.
