it is mostly digitalization though not just bitcoin. for example when we use our bank cards (debit cards?) instead of cash that is exactly what you mean and it has nothing to do with bitcoin. the problem is people still continue to use cash so it won't solve this unless it is a 100% removal of any usage of cash which is impossible. at least for many years.
Agreed, but adoption of Bitcoin will reduce "Cash" on your premises and this will reduce cash transports. If you were a robber and you had to chose a target between a merchant that are cash only and another merchant that has a "
Bitcoin accepted here" sticker in the window, which one will you target?
I can imagine how in the future criminals would be mugging Bitcoin users and robbing stores that accept Bitcoin, because it would be better for them than bank, since Bitcoin will always have some degree of anonymity and will always be irreversible, unlike banks. There will be some complications when compared to cash, like the need to scan QR and the possibility of double-spend of unconfirmed transactions, but violent Bitcoin and crypto robberies are already happening, there were many reports about people getting robbed at gunpoint in their homes or on the streets. So, Bitcoin will save some lives due to digitalization and making practices like armored trucks obsolete, but security wise it will always like gold or cash.
