assuming you are not a fraud and you are serious, never share access to your money accounts, wallets or any service where you hold funds. Do you understand how it risky is?
btw. How do you think that access to your Binance account can be valid as collateral? If you have enabled 2FA, he can't control what are you doing on there, nor can it be charged in case you start avoiding repayment.
I slightly can predict the risks here, but I do not have any collateral materials to prove my words, I thought this account could help me.
If I was you, what kind of collateral things you will prefer (i saw above links post, i don't have any domains or other stuff). Need some suggestions.
The "suggestion" is clearly one and only. Since it's certain that nobody will give you anything without valid collateral, you will lock your thread (use the down left link) and you will look elsewhere to get the amount that you want. Simple and easy.
