Saw this one coming from a mile away as well. It's usually a good indication of a scam when they stop replying to your messages

They seem to be functioning still though. Maybe not for USA residents. I do have pending withdrawals now, will update if my BTC ever gets out. Would love to hear back from anyone that has done recent transactions with them outside of the USA. I have seen threads on this forum that suggest people HAVE been able to get withdrawals in 2018, but not many... I have also seen a couple of stories of people NOT being able to get there BTC out... so... yea... anyone? lol
