The first thing to consider is the regulatory environment surrounding Bitcoin in your country. If there are no restrictions whatsoever, owning Bitcoin wouldn't cause much concern. When Bitcoin has clear regulations regarding its usage by residents, small-scale sellers will gain more confidence in introducing their own exchanges, knowing they are not breaking any rules.

Now, let's talk about the reputation of the dealer. Trusted dealers usually have fair regulations for both parties involved in a transaction. This includes how identity and reputation can serve as guarantees.
Digital exchanges are more dominant here, as only about 5%-7% of the population is aware of Bitcoin. Personally, I prefer exchanging cryptocurrencies for fiat using exchange platforms. The prices are more up-to-date, and the process is relatively quick. After that, I withdraw the funds from an ATM for daily needs.
