Generally, I don’t get involved.
But if you’re in a developing country, even if your postal system is reliable, it’s hard to get sellers over any perception that you live in a mud hut and must be defrauding them.
Bank wires can be recalled, and take a while. My bank even charges $25 or so to receive one. Maybe Western Union would be an option. Bank drafts and cash can be counterfeit, let alone hard to get in my local currency (Canadian dollars).
As a seller, I would directly accept a handful of country’s payments directly, and leave the rest in crypto-only via a payment processor that pays me in $. That maximizes my revenue and minimizes my hassle.
