Hi i want to lend some bitcoins and i dont knw that giving of the id national id card scanned photo is safe or not ... i dont know if anyone can help me ..
No, it is not safe. You can't sell the scanned ID to get your coins back.
If you want to lend coins, always ask for a collateral (that you know you are able to sell and get your money back if the lendee does scam you) to be provided to a trusted third party for the time being.
