Alright, since you're going with this, can you instead sign any quoted addresses from your BiPolarBob account?
Take your pick between
this one,
this one or
this one. You can sign any message so long as it is dated with the current date.
Or, have you forgotten the password to your wallet too?
Nonono, he's got a way better excuse for that, he simply never reuses addresses.
Maybe he will tell you he deletes the private keys once he used an address
(Would quote you the post from BiPolarBob4, but it seems that account got nuked )You should not ever reuse addresses that you have previously received BTC with (including change addresses). Although you should also not ever delete your private keys either
The OP is clearly a scammer for many reasons, however notably because the "real" BPB tends to instruct people to send payment for gift cards to a charity's donation address for many of his recent giveaways.
There is a chance that the OP is
Powerpuff, although I would say that it is far from certain that this is the case. It is also possible that the OP either is trying to impersonate him and/or conducted some kind of business with him.
