DO NOT DO THIS NEVER SEND ANYONE YOUR WALLET.DAT FILE
This member has given bad advice to you under no reason should you send anyone on here your wallet.dat file chances are they will steal your coins.
Yes, usually you should be very very weary when someone tells you to send your keys to him.
However in this case, this is not a bad advice. I am simply offering my service to someone less familiar than me with this.
Everybody should always do their due diligence. You can check my
escrow thread here and take a look at my
Trust feedbacks.
If there's 0.01
BTC, 1
BTC, 10
BTC, etc... in that wallet, it is all the same to me : not my money.
If OP is interested, we can reach an agreement and establish a secure trade.
This is why I said if he wants to do it, then he contact me first here with a PM or by Telegram, because I will never contact him first to prevent impersonators.
Good luck and stay safe !
