People have invested in bitcoin, and at the same time, some people have sold their own investment. That is how the market works, in my opinion. When other people are selling, people are buying. However, what you said is right, and it's a new thing that some people may gain and some people will lose. That is how it works, we all know, but we pray to always be on the safe side.
However, people who make a decision to receive payments in bitcoin while selling goods or services for people are at their own choice. We can’t force people to do that because they accept bitcoin in the region. Not everyone has knowledge of bitcoin, and not everyone has bitcoin to purchase something and pay back in bitcoin. So you can see that if a person wants to do such business, they indicate that they accept bitcoin and fiat as a method of payment. If not, I don’t think that business will go well for such an investor or businessman.
