I don't understand what Kate is doing. If she can't honor her debt, she should announce CipherMine's bankruptcy. She should liquidate CipherMine's assets and the proceedings of this action should be paid to bondholders. If there is anything left (which there won't be), she should pay the rest to CipherMine's shareholders.
It is unreasonable to expect we could get our whole investment back. But Kate should act on her own words and move ahead as she promised she would in a situation like this.
Not only is Kate building up an untrustworthy reputation in the Bitcoin community which might affect her future career in technology. By being inactive, she is also incentivizing us to carry legal action against her, the costs of which she will have to cover. And she clearly IS breaching the terms of contract if she continues to operate CipherMine.
