It looks like there are serious operational issues with CryptoMixer.io. OP, I saw that you were there, I assume that you are following the development of the situation.
Many complaints about long delays in the withdrawal of funds, and transactions stuck for days.
They do get downtimes, but the good news is they usually work on processing the transactions, though not usually in a quick manner. The newbie accounts registering in the forum just to make complaints and then later on saying that the issue was resolved might be because the only way to get to cryptomixer publically is through their ANN since there is No twitter or Reddit
This was their update this morning
SERVICE IS ACTIVE
Kindly note, we have completely fixed the issue. All delayed transactions are processed. The websites are active for about 10 hours. We keep monitoring. Sorry for the inconvenience caused.
Feel free to mix your coins!
