Why do you have 6 users on localbitcoin's website blocking you?

That is a little concerning to see since transferring such large amounts like this you would want to be confident in the person you are trading with has not problems or issues that can have any payments sent back for whatever reason.
Atleast that is what I would think.

Sometimes,btc prices down,localbitcoins prices didn't change right now,so I cant accept the old prices.
You can check for yourself.
