This is due to the poor understanding about crypto currency or the knowledge was conveyed to them wrongly.Digital currencies is different from virtual currency,digital currency means using fiat in credit and debit cards but crypto currencies are currencies which used by blockchain technology and we no need third part help to use crypto currencies.Bitcoin will give the freedom to use of money as we want so if people want that freedom then move to bitcoin and crypto currencies.
Its true. There are still lots of bitcoiners who has lack of understanding about the existence of bitcoins although they are into it already. But anyway in a long run and for futher studies soon they will be knowledgeable enough to understand the usage, flows and how important it is and how lucky we are to be a part in this cryptoworld.
