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.
Are those experts are from the banks or a traditional market?
If yes, i expect them to still say that Bitcoin is a bubble because this has been a big threat to them.
Bitcoin is a good investment for long term, you can see its price trend and you will see that its more worth it to hold for long term and just ignore its volatility. Dont focus on its volatility, just see Bitcoin as your long term partner, if you are a trader then you have no choice but to adopt and make a good strategy on how you can deal with the volatility.
