Poland is so shitty country, I observe that for decades. This is a closed loop. You cannot stand out here. Even if you should.
If you think so, maybe you should have moved to another country a long time ago and started your business there - although I don't believe that you could expect better conditions in some other countries that are nearby. The east of the EU is quite different from the west, and it seems to me that this is, among other things, a consequence of long-term exposure to communism, the influence of which is still felt in some countries.
Wait a minute, are you saying that there is a way of exchange in the sense that I send someone cryptocurrency, and he sends me money via letter? Even if there were such a way of exchanging, how would one ensure that both parties kept their end of the bargain? Coin in escrow until the other party confirms receipt of the envelope - what if the envelope is lost or someone in the delivery chain opens the envelope and takes the money?
When money is sent by letter, such shipments are usually declared as letters with a value that are insured for the amount contained in them - but this service also has a price.
Well, yes, after I wrote that I thought about what you say here. I'm sure I've seen those exchange offers for cash but I didn't look at the details, maybe it's to exchange in person if you live in big cities but I see it as even more dangerous. But I'm pretty sure I've seen some for cash via mail. And then I thought that as you say, it is generally forbidden and if you send cash it has to be with a money order. So no privacy there either.In general, it is not prohibited to send money in a parcel (as far as I know), but there is no guarantee that the money will reach the end user, because anyone in the delivery chain can steal the money, and if you did not declare the parcel as it should, there is no possibility of appeal.
