I think I may have made the mistake of buying 0.3 Bitcoin through Bitilicious but sent my sending adress instead of my receiving address. Is there any way I can Get my Bitcoin back? On the Blockchain its marked as unspent but I don't know wtf is going on as im new to Bitcoin. Does anyone have any suggestions? Thanks.
No such thing as a sending address and a receiving address. The address you "send" coins from can also receive coins.
It sounds like you are using bitcoin core which has these 2 parts in the menu which are called similar to sending and receiving IIRC. The sending addresses belong to someone else you send the coins to. See if you can remember who and contact them.
Actually, some web wallets have that feature, and if bitcoins are sent to the sending addresses, then another user will get credited.
