Well-known in the financial world, the maxim "Cash is King" expresses well the meaning of liquidity. When cash reserves are said to be more valuable during periods of economic uncertainty, investments on which the country's wealth is tied up into are considered to be harmful, although rare. The reiteration of this philosophy applies in traditional finance but finds strong resonance within the crypto ecosystem, which is notoriously turbulent.
Cash can be slightly loose in meaning when applied to the crypto ecosystem. It may refer, also, to digital assets that pose the highest liquidity, such as stablecoins or cryptocurrencies meant for real-world transactions; thus, Bitcoin Cash (BCH) finds a special mention. BCH was essentially created as a version of Bitcoin, targeting day-to-day payments with more emphasis on speed and cheaper fees. These attributes are what makes BCH a better fit for the definition of "cash" in the crypto world, qualifying it as a store of value, while also working as a medium for real-world transactions.
Market pressures push more investors towards holding stablecoins that they believe are price risk minizing assets. However, there is a more layered strategy of segmenting part of the portfolio into crypto assets that actually have a certain utility. BCH excells in this because, without liquidity, it can also be used as payment for merchants and platforms that support it. This dual role allows for more flexibility on the part of investors: value is being preserved, yet it is possible to transact.
If 'Cash is King' in traditional finance-underlining the pressence of liquidity in survival and opportunity-in crypto this principle can as well be made applicable by coexisting cash-like, liquid stablecoins with utilitarian currencies such as BCH. Investors holding BCH do not hold entirely liquid and tradable assets but hold even possible digital 'cash' in which exchanges can be utilized on practical obtainments in actual economy.
Liquidity is king in the end. Liquid selloff in a hypo fast-moving crypto space provides those who hold liquidity with the optimum level of the market in terms of opportunity in lower prices. BCH can be part of that strategy-fast, not expensive and functional proof even in the crypto world that the age-old axiom still holds true.
