I prefer having crypto currency to cash, because crypto currency can appreciate in value,thereby allowing an increase ,which will make me have more money,then later I can convert it to cash when the needs arises.I prefer cryptocurrency because It's faster, cheaper, more secure and immutable. Cash is controlled by banks while bitcoin has owners. Less volatile. Due to this feature, it becomes easier to conduct transactions across boundaries and online.
But ordinary if cash is not put into investment,no form of increase or appreciation.
