This is how money works. If you use a medium of exchange and unit of account for goods and services then that medium must increase at the same rate as the increase in goods and services otherwise you get second and third order effects such as inflation, contraction, rising unemployment, etc., directly impacting its ability to act as a unit of account.
In Bitcoin you don't generate cash, you earn block rewards for acting as a consensus broker which otherwise would require a central banking settlement layer. This activity, tied directly to the transaction layer, acts to maintain the equilibrium between increases in goods and services and expansion of the money supply.
Wall Street got ahold of it and now Bitcoin is primarily acting as a Store of Value for the purpose of speculative investments. Driven primarily by the fear of missing out and market manipulation since Bitcoin is heavily centralized.
