If it were guaranteed that the price of bitcoin would stay the same as it is today, would you still buy it? My guess is, the answer is no. But if its value lies in being a currency, price stability is essential. And if your answer is no, how is it then not just a Ponzi scheme? In other words, everyone is buying it on the hope of someone paying more for it in the future, not to use it as a currency.
assessment and question that is very silly, it illustrates that you really do not know anything about bitcoin. so, my advice to you
learn and read a lot from references to bitcoin. then you can draw a conclusion after you really understand and know about bitcoin or other crypto.
