Really need more details if you want help.
What wallet did you use?
What coins did you loose access over, the 7btc or the 0.715 btc transfer?
What did you engage in during you p2pool mining days that would cause this?
The coins are back now.... so everything is normal! But it defiantly scared the piss out of me for a little bit! LOL
I use MultiBit.... I use the default wallet in it. I lost access to the value listed in the subject for what appears to be one transaction or so (my spendable balance went down by the amount in the subject).
I did run my own P2Pool, and I had about 2.2 TH/s from February until fairly recently (mining just isn't as profitable as it used to be). It was a merged P2Pool, but nothing special.
I am going to assume it was all the smaller deposits of coins.....
Thanks for your offer of help anyways!
