Bitcoin is a long way from becoming a currency you can live your life in. You also only have 7 transactions a second. But that doesn't mean Bitcoin isn't immensely valuable as a medium-term and long-term store of value
I get the point the most of people would not look Bitcoin as a good option for transaction for its price is not stable and always changing. Yet there are posting thing that could be a reason for people to believe on Bitcoin. Its price may experience limitless possibilities to develop and to experience growth so it is technically good for investments and trading which is a good thing for people because it could give a possibility for people to earn and to have profit.
This is why bitcoin can be very confusing, bitcoin which was designed as a currency right now does not work very well for that, one would expect the value of bitcoin to reflect that but this is not the case because for a lot of people bitcoin is an investment and as an investment bitcoin is great, so it is odd that bitcoin has such a high price, but that is the law of supply and demand, and since there is a big demand the price of bitcoin is huge.
