How to Handle this situation
- Always use a new wallet address and stop using the same wallet address again and again for receiving Bitcoin.
- Never share your personal details with anyone, avoid using the same password on the different website, don’t store your private keys in a cloud server, many people click private keys photos and save that in email or google drive or Dropbox.
- Store your coins in multiple places, use hardware wallets like Trezor or paper wallet.
- Don’t share your wallet address in a different place if you are concerned about your privacy.
I hope you will take care of all the above points if you are worried about your privacy and also want to keep your wallet safe from scammers.
