Everything works fine a few days ago
I've just mixed my bitcoin and withdrew a chip on the 6th
and then the next day I created a voucher code for the left over
I doubt this mixer goes scam at this moment, there isn't any hint towards that
it's probably its usual bitcoind (or wallet) hiccups just like what happened a few times before
They topped up the campaign escrow with a 8.192 chip the weekend before last. That doesn't strike me as the actions of someone about to pull an exit scam, it looks more like someone who knew they were going to be busy. I'm sure whatever they are doing they will still be checking in on the service and the support emails whenever possible.
You can see from reading back through this thread that every time there have been technical issues they have been resolved and nobody lost any funds. Trust is built up by how you deal problems and ChipMixer has always come through.
