Hi, I have send my bitcoins to one of the bitblender sites,
not sure which one though I have opened a new account and tried to contact the original bitblend support team, but still no answer,
If you did not know which site you sent your money to how to do you expect them to reply to your question? You say that you had sent to ONE of the bitblender sites - you need to be specific here.
My question is, there is any way to get my bitcoins back/cancel the transaction/ track the website which I opened the account?, etc...
So basically you did not even know the owner of the address that is the site you were sending the money before you sent it? There is no away to cancel a transaction in the blockchain, so thats out of the question. Tracking the website? I guess you can try looking up the address you sent the coins to in order to know the owner site. However I really doubt that they will help at all because the fault is from your side from as much as I can understand.
