> Infrastructure company has to find an exchange to trade OTC as often as possible to protect against as much volatility as possible, while keeping in mind the minimum OTC trade size is generally $250k USD
One can loosely think of an appreciating cryptocurrency as a short-term loan. You're out cash up front. Later, and only later, you get it back plus a little more.
The infrastructure company in your example is thus, by turning cryptocurrency's promise of cash tomorrow into cash today, providing maturity transformation [1]. This is one of the core services of a bank. It is also an inherently risky business on account of the asset-liability mismatch.
