First of all, we would love to once again clarify what the actual meaning of the term last IP is, which was included into the screenshot above. Its the IP address that the certain user used for the last time of logging in into the FJ account.
On another hand, the IP address (107.77.204.49/)
I reviewed the "shared" IP address and discovered this IP belongs to my my work office wifi.
I looked up the
whois for the IP address in question, and it appears to belong to AT&T wireless.
I cannot rule out this IP address being a hotspot for AT&T wireless customers, but I think this is pretty unlikely. If this IP address belonged to your office WiFi, I think it would probably be more likely to belong to AT&T Uverse, or whatever their trade name is for serving business customers.
If I am understanding correctly, FJ told the OP they didn't want him gambling at their casino anymore, and the OP subsequently used another account to gamble at FJ's casino, and won 5 btc. If this is true, FJ should allow the OP to withdraw his deposit if they haven't already, but they do not owe him his winnings.
