1. The last time I checked, this was not about "buying and selling online". The seller stated clearly that they exhausted all options to complete this transaction online. Seller made it clear they will only complete this transaction face to face in their country. So your statement is not valid.
Let him give you a legit reason why he can't or won't use escrow?
I referred "banking backed escrow services" by "buying/selling online"
I don't think all people love such escrow services as well as making transactions with banks. Some people are also not capable to use banks. You may want to search "unbanked" to learn more.
2. The buyer offered the seller to even have a lawyer come in person on his behalf to complete the sale in their country and the buyer still refused.
I missed it, sorry. But it should be related to privacy even though it's difficult to understand for me too.
Buyer wants to see seller face to face on their soil.
Again it should be related to privacy.
Crypto is always an option, but safety is best with escrow.
Safety and privacy are best with crypto backed escrow services, if the problem is limited to privacy only.
Identity is a flawed argument too. Why? the buyer wants to meet face to face???? so they are not hiding who they are??? so cypto is not necessary.
So if identity, security, and the convenience of doing the deal with a representative in person are all rejected, then what is the buyers motive here?
cyrpto is necessary for not only privacy but also for safety, speed and low cost. Cyrpto based escrow starts and end in less than 1 hour, its cost is 1% or less, is safe as payment can not be reversed back by the buyer.
Identity isn't a problem. Identity document is the problem. The most critical problem is that escrow services that work with banks want identity documents of everyone, sellers and buyers. They ask everyone to send their most private documents like ID documents, passport, utility bills, email address, phone numbers and more. More and more people don't trust such organizations to send their personal info. They might sell personal info of people, might not keep those documents private, their organization can be sold to someone else, etc. You can't trust them for your most private details of your life, and shouldn't trust anyone, any organization online. You may send your documents to 1 site if you have no choice and if the money you will receive is very critical for you. But there are many sites that ask ID documents. While thinking you are safe with an escrow service or with a middle man, you and your buyer are taking a much bigger risk that doesn't end for long years, by sending your documents to an internet based company.
And you are telling me the seller has no right after this to know more?
Customer is obligated to make payment only nothing else. This is sad but true. This is also not limited to the problem of this buyer, plus this buyer may have other peoblems too. As a seller you must provide solutions to each and every problems of your buyer or you must look for another buyer.
They should just pack, spend 4 figures to travel and hotel and meet someone they know nothing about in a foreign country to do a deal. This is like craigslist gone wild.
There's no problem with travelling. But a poster above said USA doesn't want foreigners to enter. The OP may refuse to travel to USA by using this visa barrier argument. OP should be ready for a weird request: Buyer may ask him to sell the domain in the airport
LoL
I'm into online privacy but don't lose your brain in the process.
You can't force a buyer to send his ID documents and his most private personal info like home address and phone number. Losing brain is to send most private documents and most personal information to everywhere. If you send your personal documents and info, you can't know what will happen to you 5-10 years later or 20 years later. Those documents and info are kept for unlimited time, are never deleted. You can't guarantee that companies will never go bankrupt or will never be bought by a person from a country with very different privacy, trade and civil laws. You can't know if your personal info will be stolen by a hacker after 3-5 years. Even you can't know if someone else (your email provider, someone on the internet, someone who has access to your computer, etc) receive your documents while you are sending or before/after you sent.
There are too many unknown factors when it comes to safety of your personal info and documents in a digital form or even in paper. It's really not worth to sell/buy domain for $100 to take such never ending risks. This $100 amount may be as high as $50,000 even $500k for privacy minded persons with higher standards, there is no upper limit of it.
