yeah that's true. i know surely that even as we proclaim the importance of bitcoin over gold doesn't mean that bitcoin is risk free. one of the most risky part of bitcoin is loosing access to your wallet, that will automatically make a person lose all his asset forever.
there are guys who made such mistake back then and to day they have lose access to their wallet forever. example of such people are
1.
James Howells who lost a hard drive containing 8000 bitcoin in 20132.
Stefan Thomas is also another guy who lost access to his hard drive containing a total of 7,002 bitcointhere are many folks who lost access to their wallet and that is how they lose fortune forever so it is good to prioritize safety or safeguarding our seed as that the most important thing in bitcoin investment. that's why it is often said that not your key not your coin, this implies that if it is lost you also lose your asset.
This is a very low risk scenario. These days almost all wallets try to force you to create backups. If you don't do the backup or if you do do it wrong, it is more a you problem not a Bitcoin problem. A much bigger risk for normal users is getting hacked I would say.
