Is ETH losing value?

Good day, I'm quite new to the world of cryptocurrency and I've been hearing a lot about Ethereum, or ETH as it's commonly known. I've noticed that the price has been fluctuating quite a bit recently, and I'm starting to worry that it might be losing its value. Could you possibly provide some insight into this matter? I'm particularly interested in knowing if the technology behind ETH is still as promising as it once was, and if there are any factors that might be affecting its price negatively. Thank you for your time and assistance.
