The two men behind the purchase and sale of the house in Portugal have a strong faith in Bitcoin, which is why they took such a big decision. Their decision is really commendable.
There have already been 13 purchases/sales of homes carried out with Bitcoin.
That is, there are more and more people trusting bitcoin and using it to buy high-value goods, such as a house (and houses in Portugal are at very inflated prices).
This proves that slowly people's trust and confidence in Bitcoin is increasing. According to your information about 13 houses have been bought and sold through Bitcoin transactions so far. Its number may increase. We know the news that is usually published. Maybe there is a lot of news that we don't know. Some buyers or sellers may have bought and sold their homes with Bitcoin without telling anyone. But in any case, Bitcoin is making progress.
We want people to not limit their Bitcoin transactions to just buying and selling houses. Let people use Bitcoin as a means of transaction in other areas as well.
