Yeah it looks like they just disappeared and gone underground, but I think they are still working on making serious changes and introducing new privacy features with exchange and other improvements.
They told me that they will implement automatic payments for daily rewards. I have no idea about other updates.
In isolation, if you look at the bigger picture their email support does not seem to be to a high level and an explanation is needed about the 12% APR for anonymity mining therefore apart from these two issues there do not seem to be any complaints and that is a good sign.
Indeed, there were no other complaints so far about them, excepting the mining rewards and the lack of support... At same time, I don't know if the problem with the daily rewards is a systemic one (meaning if I did not get the rewards in a specific day then all 566 depositors also did not get their rewards or a random one (meaning that only a few random users out of all 566 depositors did not get their rewards in a specific day).
If the problem is systemic then it's a bigger one. Imagine that all those 566 depositors would be supposed to receive 2000 sats in a day. If the problem affects them all, then this is a missing payment of 2000 sats x 566 users = 0.0132 BTC, which is a serious amount. Now if such problem occurs 10 times in a month, the mount goes up to 0.132 BTC. And so on.
Obviously, we can't know what amounts in daily rewards are supposed to be paid to the depositors, but I just gave an example.
