Damn. Somehow i missed this. This is really, really impressive. I assume they didn't receive the 4800
BTC in a single go, but still this goes a long way to proving that Chipmixer is either a honeypot

or pretty legit, as the article does seem to insinuate that the funds flowed in in vast amounts.. (Thus the perfect time to exit scam, if they had wanted.)
First time to see this also which is really amazing and about OP's issue, how come they would just turn out to be a scam just having an issue with $200? hehe.
@OP just wait up for their response and don't worry yet you are dealing with a legit Mixer.
