Hello please remember some points
1. Without fluctuations you won't even have an interest in Bitcoins, this is what makes people invest. The fact that its a cryptocurrency does mean its not a fiat !
If it was supposed to be one it would have been, its beat at what it is.
2. Fluctuations are also very common in your common currency but ! * They are not as frequent and at that level of bitcoins* , but yes ever currency gets fluctuated according to the economic growth of that country, that can be both positive or detremintal.
3. If its a fiat, might as well we buy dollars then because then everything will remain the same .
Thus we should stop comparing bitcoins with fiat .
I see the Bitcoin price fluctuations in two ways:
1) It is similar to the stock market where stocks are constantly fluctuating in price due to various factors such as recent news, earnings, profits, supply, and demand. Stocks and cryptocurrencies are subject to the free market rather than run by a government.
2) Trading would not be possible without fluctuation in price. If you buy low and sell high, every drop is a buying opportunity and every rise is a selling opportunity.
