I have a suspicion that the person who lost the BTC might be the same one giving out those contact details or advices. They could be trying to trick others in the future who search for help online. Google might suggest similar questions on Quora, and people could end up sharing their private keys with scammers.
So, if you are new to all this, be careful. Don't trust random people claiming to be experts on Quora or anywhere else. They might just be trying to get your private information.

It's really a very large amount, but how can someone who has more than a thousand bitcoins be fooled so easily? People who have that many bitcoins should have greater knowledge about bitcoins and also bitcoin wallets, or maybe it's a wallet that he has long forgotten (Sorry I didn't read the entire contents of the article). in this world there are many tricks that are used by fraudsters to trick their targets, therefore I will never share my personal wallet data with other people even though I cannot access my wallet again, it is better for me to create a competition and for those who can open my wallet, I will immediately give you a few percent, always remember "it's no longer your bitcoin, if you give your key"
