With some of the delays and issues involving BitcoinFog recently, I decided to try out MixBit (http://mixbity3bxwsqmnn.onion). I first sent 0.3BTC to test them and they sent the tumbled BTC within 20 hours.
Then I sent 8BTC. 36 hours later I hadn't received anything so I first checked to make sure that there was a tunnel record for the from/to addresses (there was), then I sent an email to their support address listed (mixbit@safe-mail.net) asking what happened. They responded the next day with "Your transaction is still pending. It'll end up into your wallet later today.".
That was a week ago. I've sent emails every day and I can see that they're being read within 30 minutes (since safe-mail shows you when they're read if both the sender and receiver are using safe-mail.net), but they haven't responded again and I still don't have my BTC.
Mods, please remove their link from the sidebar. I can provide proof if necessary. I'm trying to keep my hopes up, but it's not looking good. This fucking sucks.
This is terrible. I am so sorry this happened to you and it is completely fucked that they tricked you with that first successful transaction. I am removing their link from the sidebar now.
EDIT: Since they're reading your emails, I recommend sending them a link to this thread. Maybe the bad PR will make them take action and give you your coins along with a bullshit excuse. Keep us updated.
EDIT #2: If /u/mixbitsucks actually sent this thread to MixBit support and any of them are reading this: over 8k potential customers (we average around 35k pageviews per day) can see this post and come to the conclusion that you are huge scammer douchebags. Make up a bullshit excuse, apologize, and give this guy his coins.
