Update: I still have not received either my SiaFund refund nor the BTC to complete the trade.
Waiting.
Wowww What a Saga we got here. Personnaly, i have a feeling that Bignox is the troll and the hacker here. He probably want to be on the « friend side » to escape suspections. Skatebird is probably an hacked account. Sorry, but you wont get your money back:/. IP adress is far from a proof for that kind of stuff. Be careful vs Bignox and also skatebird. Always use Escrow. You can try to talk to police but i dont think they will do anything with this story.
