From the information I know, the missing bitcoins to date are quite large.
According to the New York Times, there are 18.5 million Bitcoins. About 20 percent, which is worth $140 billion, has disappeared.

Even to be hacked it would be very difficult, even very impossible to do.
So if you have lost your bitcoins, try to remember where your wallet keys were and you wrote them down. Is it written on paper or you save it in the computer. If after doing this and you don't remember your bitcoin wallet key at all, or you don't write down the phrase at all. That means you have to be able to give up the bitcoin that you have.
Therefore, if you want to buy bitcoin and store it in a non-custodial personal wallet. Don't forget to copy the key/phrase, and keep it in a safe place. That way, the key won't be lost and your bitcoins will stay safe.
