Why the value of the Bitcoin is not always stable?

[emma.lee1890]

The reason is that it was profitable for someone to raise the price to $ 20,000, in order to sell bitcoin and make a lot of money on it.
When the buyer getting too much then the price getting more expensive then when there are too seller than buyer, the tendency was the price will be cheaper and that's why the price getting volatile.

The name of the trade goes up and down the price is reasonable and it depends on us alone can take advantage of the situation. If the value or price goes down continuously, we can use it because to get a bigger profit from it

You know that it is the basic characteristic of bitcoin. It will be always volatile and unstable because it is decentralized and no one controls the price. There are two big reason why the price is not stable and volatile: (1.) The demand of investors  (2.) The current issues. If the demand in market decreases, then the price of bitcoin falls down but if there are many demands in market + rarely people to sell the bitcoin, then the price will rise. In addition, the current issues can contribute to influence the price. Investors will consider to not buy the bitcoin temporarily (negative issues) or they will buy on a large scale (positive issues).

This is really because of the price being tied to the law of supply and demand. The more usage and the lesser coin  supply remaining the higher will be the price which means that anytime when people would sell or buy a change in the value could occur due to changes it the volume of coins being used or is supplied to the users. Where demands and supplies change the value changes as well.

bitcoin is also trading just as other market products are trading on the local and world stock exchange and those price(s) aren't stable.

Certainly that creates the volatility of bitcoin. Stability may only be achieve if people will regularly use bitcoin in transactions as a payment system or as a currency. If people will just be holding it and selling when price is high the more volatile will it be.
