If you tell people that you bought stuff in the internet or even in a shop with Bitcoin, people will become aware of Bitcoin, more so if the stuff that you are showing them have value when you bought it with fiat money, what do you think about this?
Bitcoin was not created to exchange for fiat currency (euros, dollars, etc.). Bitcoin was created to be an exchange between products or services, directly. What happens is that, because its value has become excessively high, it has been used as a speculator. But we must bear in mind that it is a volatile price for companies or microenterprises. Although if today you decide to buy me a house with bitcoin, and if tomorrow the price of Bitcoin rises, then I will earn double. There are already some companies that have decided to receive Bitcoin as a payment method, they know they can earn much more in the future, because their value can continue to grow. Although it is a matter of risks, because its value can also go down and lose.
