If you notice a little, you can see that the price of bitcoin is constantly falling down.

If this was the case, why isn't it into negative numbers yet? Your account was created in 2017. Do you think the price was higher or lower back then? Follow-up question: do you know what the word "constantly" means?
There are certainly some reasons behind this that I am clear to you if you have such information, don’t mistake to share here. The reasons why its price is generally low is epidemic or regional political, unstable market concern, technical reasons, economic conditions may be called NIM and upward based on these conditions, but what kind of problems can we create here if we have? Everyone has questions.
The price isn't "low". BTC is up 18% over the last year, which is better performance than much of the stock market or anything that has a lot of liquidity and is tradable.
