If you are a really an old hodler then you already answered your own question. How can you safely got this far if btc isn't safe from being hijacked? Because, if it did then it was being hijacked long time ago. They have a better chance doing it since the network that time is much weaker and the prices are less expensive than compared to today yet they still didn't do it. That simply means that btc is truly strong and cant be hijacked.
What the governments are only doing is they create their own kind of bitcoin/crypto which is centralized that they can fully control but no one is going to buy that. There is only one literal hijack that can happen you, that is if when you are not careful on securing your bitcoins.
I agree, there are too many people who are constantly afraid that they would not have the thing they are looking for and they keep fearing that one day they are going to end up losing it all. That anxiety over something that did not happen yet, is a psychological problem. I personally feel like talking to a professional would help.
If bitcoin came all this way without any problems, then why would it start to have any problems in the future suddenly? Of course it won't, but there will be some people who will always be afraid of this, they will always think that out of nowhere, suddenly the bitcoin price could crash because of some problems.
