Well that sucks. Glad I didn't buy too much of it.
IT is 100% nonsense.
They are working on a refund/buyback. Escrows are involved.
Lauda has been active on bitcointalk (she is one of the escrows). There were three developers, one left and these two can't see eye to eye. The current course of action is a refund/buyback and then they would go their separate ways, both develop their own projects and potentially airdrop coins to NVST holders.
The author, Cool4y (Emanuil Pavlov), was kicked out of ever NVO community chat that existed. Ton banned him from slack, discord and telegram. He suffers from multiple personalities, is a pathological liar, a horrible racist, etc.
Right now, the rumored buy back price is going to be somewhere from 60c to $1.00. Depends on a few things though, including BTC price, how much of the milestone funds that were given to the team are still available, etc.
