So now the question is bitcoin safe from hackers?, can it be stolen?
With someone carelessness, Bitcoin can be stolen. Once someone is lost with his or her private key or seed phrases,someone Bitcoin can be easily stolen. But if your private key and seed phase are only known to you and nobody gets access to them, it is very impossible for anybody to steal your bitcoin. So the important thing to do to avoid having your Bitcoin stolen is to provide proper security for your Bitcoin wallets by hiding the privacy and seed phrase wisely in a location where nobody will get access to it, unless only you or the person trust and show where you hide those your private key or seed phrase. Please think also about what happens in case you have an accident. Here if nobody knows about the keys, the bitcoins are gone. If people know where to find the keys, this could increase the risk for you to have such an "accident". Plenty of divorces and former partners fighting about every cent.
My suggestion would be, to make a will and leave this at a lawyer or so and add an envelope to a specific person with all your Bitcoin details. But tell nobody about this. So you change this at any time, and in case of an accident the Bitcoins are not lost..
