Price stability happens at the exchanges. If you want to buy or sell a currency, and there's millions of buyers or sellers on the other side of the market wanting to take your order, you will see a very small change in price movement from your trade.
Day by day New traders are starting their trading career and based on the buy and sell orders, the price changes, if that doesn’t changes how anyone can make profits on their investments? But it should become somewhat stable so that more opportunities increase along with the market price.
That's the principle of trading I guess, the loss of someone is the gain of someone as well, they have relativity and each time you enter this market fluctuations follows, as traders will buy and sell the volume will increase or decrease depends to the trend, buyers will hold and wait till they gained
while early holders will sell out with their profits, unless you are not so familiar with the movements you won't see any difference but having good
knowledge even in small form you will be able to increase your investment little by little.
