You are very right sir, saying that Bitcoin is risk free is very much misleading because we live in a world full of uncertainty, anything can happen in the future that may be out of our control, so it's not proper to be saying that Bitcoin is totally risk free, because being alive is also risky if he doesn't know.
The major risk I can agree with when it comes to bitcoin it's the fact that scam or hacked attacks are so advanced as much as the protective tools in bitcoin but then we have a big and unbroken solution which is storing your assets offline in an airgapped devices and cold wallet, this is quite a big way to say that bitcoin is now less risky once you have this offline wallet well managed for your bitcoin safety.
No scams and hacks are not the major risks that one should look at when it comes to bitcoin, because when you are careful enough and know your way around bitcoin you can never fall for scams and possibly hacks. When talking about risks, we are looking at something that can affect everybody that has invested in bitcoin. We are looking at the wider picture here, something that when it happens everyone is affected irrespective of how careful you are or not. And that is the risk of bitcoin price going down to zero. This is the biggest risk that's associated with bitcoin. Even though I don't see the possibility of that happening, but we can't neglect the fact that such risk still exists in bitcoin. This is the major risk that all investors should be more concerned about.
It is why learning before deciding will be necessary for those who want to invest in Bitcoin. With so many resources they can get, they will learn step by step and have the right information that they need. Bitcoin have its risk so from their learning, they can be able to prevent the hacking or scamming and will not let them getting to that thing. And yes, Bitcoin have fluctuation but that will not be a problem for those who can manage themselves and not panic. If the price is down, they can still hodl and wait while they can still buy more at a low price and keep hodl. The fluctuation will always be in Bitcoin so we don't have to panic but use that moment for our benefit.
