In my opinion, it is now difficult to say that the krypto coin (bitcoin) is used as the main medium of exchange, only for medium payment, because now the krypto coin has developed which used to be a medium of exchange turned into an asset where if something has become an asset and free to be traded, if it is free to be traded, it has entered into the trading field of free trade. So in the present the function of a krypto coin has changed or developed into two functions, namely as a medium of exchange / medium of payment and an asset and that is very reasonable. All we have to do is choose our needs for the krypto coin. For the realness of a krypto coin used in everyday life, I have tried it where the type of krypto coin that I have, I convert it to basic necessities where in communities that have crypto coins it provides such a marketplace that provides basic needs to be exchanged for coins the krypto.
