We are all aware that it is take time to transfer BTC from one wallet to another one. In this case when you are purchasing something big with BTC like house or car all parties has to be secured. What is the best way to secure seller to get BTC when all documents are signed?
I think the best way is next to the seller or buyer. When you buy something really big like a car, house or say a piece of land outside the city in any case you will meet with a person to sign certain documents. In this moment, you can easily carry out a transaction by taking a laptop.
