This is why I can't comprehend how people who currently have BTC are so happy spending it, especially if they were able to mine back in the day.

Even worse, they also promote the idea to those who are new and have had to buy BTC and at a much higher price.

When governments ans central banks start to put BTC in their balance sheet, it will be impossible to ever get BTC again.

These people are either irresponsible, or in on it.
