I think The value of Bitcoin is highly volatile, and its price can fluctuate significantly in a short period of time. This makes it a risky investment, and some experts warn that the cryptocurrency may be in a speculative bubble.
Bitcoin is good or not, depending on each person's thinking. For me, it's an investment that can yield huge returns that no other asset can, so bitcoin is good for me. Many people fear its volatility, but I like volatility, the bigger the volatility the better I benefit. One more thing, you should learn about bitcoin yourself instead of listening to the ramblings of experts.
