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.
Is there any investment that is risk free? NO. Talkless of bitcoin that it’s risk are obvious, for us to invest for a long time and hold for years is also a risk, because we don’t know what will the next move whether it will rise or dip no one know, but we keep investing hoping it will no fail as far bitcoin investment is concern, However, we can say the risk in it isn’t high as other shitcoin and due to that is why it is advisable to invest in only bitcoin for a long period.
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.
One of the most important thing I always emphasize when someone is about to invest in bitcoin the first thing is to learn the security, it’s the most valuable thing any investor should know, when someone want to invest in bitcoin. I believe any investor that know the basics knowledge and how to secure their bitcoin after purchasing it, scammers won’t get such investors, since he already know how to secure his investment safely.
