Cash is known as money in the physical form of currency. Bitcoin can be converted to cash likewise steemit. Bitcoin and steemit are example of cryptocurrency, they are not cash. I met a guy and he qualifies steemit SBD as cash. Yes, it is cash but at the same time it is not. Cash is seen either as a reserve for payment. Cash is originally called money.
'To Cash' verbally means to convert to cash same goes for "cashing a cheque".
Cash is becoming a too heavy to carry around as we youths of nowadays are lazy. we prefer doing online transfer to make things easier. That is mostly or majorly the problem about cashing.
When you carry too much money in your pockets, it begins to show one way or the other, that allows you to be robbed, that is why Online Banking is advised.
