You were not on the real bitmixer.

Im assuming this is a malicious exit node changing the redirect from the homepage to a malicious .onion link instead of the real address. This is not the only thing they could change. Never trust clearnet sites when using tor. Even to redirect to a .onion url

I visited bitmixer.io and clicked the pop up link to redirect me to the onion url. But did not end up at the real bitmixer onion url

Real .onion address:
bitmixer2whesjgj.onion

Fake .onion address:
bitmix6zfuz7zmnv.onion

Everything appeared legitimate until you go to download the letter of guarantee. At which point you are presented with the following error

"Address not found."

I double checked the url to notice it wasnt correct





They did not get any of my precious coins thankfully

Novacoin

If you had a few hundred million dollars you felt like burning this might be possible. And by burning i mean investing it all in mining hardware which would be worthless by the time you were done. Since you would likely kill POW for bitcoin and another security model would be considered making your miners paperweights

If you invalidated a years worth of transactions there would really be no choice but to invalidate that chain and reset to the block before the attack

So it seems someone with a few hundred million dollars they want to throw at bitcoin has a few options

1. Waste it and attempt to kill bitcoin which would likely affect the price. But the chain would recover.

2. Mine non maliciously with their mining hardware possibly making a profit

3. Buy bitcoin and day trade

A few hundred million dollars is a lowball estimate I made. I would guess the real number is closer to 1 billion than 1 million

Sorry to hear about your loss. It could have been avoided. but all you can do now is learn from your mistakes.

Run untrusted software in its own vm, Put 2fa on everything possible, and if possible have a machine dedicated to only wallets. You dont want the host os getting taken over and the attacker having access to the vms.

Hardware wallets are another solution but few alt coins are supported.

Did I understand that right that he sent the coins to bittrex If so your best bet now is to contact bittrex. They wont be able to help much, But maybe they will freeze the jackasses account before he can withdrawal his funds
