Regarding the purchase of a house in Bitcoin, in December 2017, I sold more than 200 bitcoins to buy my first house in Australia, and I spent more than 4 million Australian dollars after all of it. If I were to go back in time and do it again, for a young man who made money for the first time, he would still do the same thing at that point, after all, people didn't regret buying 10,000 bitcoins 🍕. I'm still very consistent about selling bitcoin and spending money, if bitcoin is not spent and not circulated, how can he have a better consensus and how can he have such a large market capitalization.
