It is worthy to note that Bitcoin operates on a decentralized network, This means no central authority or government controls it, Bitcoin gives full financial security and you have privacy you alone controls your money, when you invest in Bitcoin you won't have to worry about government policy, in the time of war or conflict your investment is secured.
I will give you some scenarios where you could lose Bitcoin too.
There's a news that's affecting negatively the crypto and the price of BTC plummet 40% overnight so effectively you lost 40% of your value.
You installed a malware unintentionally that wiped all your Bitcoin and now you lost 100% of your Bitcoin.
You deposited funds to an exchange and they were hacked now you lost your Bitcoin.
So having Bitcoin doesn't mean you can't lose, it's the decentralisation where no one in charge of the funds other than you but it doesn't mean it gives protection against the financial value of your assets. Set your priorities right before wanting the Bitcoin for yourself.
