Bitcoin is quite well known throughout the world, even in countries that still prohibit its use, but unfortunately, more people consider Bitcoin as an investment asset rather than currency,
But what's wrong with people considering bitcoin as an investment? Don't you consider it an investment?
so when there is a company that advertises about Bitcoin at the stadium, they will introduce more about the company than about what are Bitcoins.
We all always prioritize our own interests. Those companies aren't the creators of bitcoin either, and what benefit would they gain by spending money just to promote bitcoin without focusing on promoting themselves? I don't see anything wrong because if we were in their position, we would do the same thing. We constantly criticize others, but what have we done for bitcoin, or are we doing it for our own benefit?
Meanwhile, regarding the use of Bitcoin as for salary payments or so on, that should be developed so that gradually the goal of making Bitcoin a digital currency will be achieved and not just as an investment asset or exchange trading currency that provides benefits because of its very agile price movements.
Apart from the legal issue, the use of bitcoin to pay employees. You also need to ask people if they are willing to accept their salary in bitcoin instead of fiat. Because not everyone likes its volatility. As we often say, don't force others when they don't like bitcoin.
