I totally agree with you...unfortunately everyone of us can only decide between crappy solutions. You have full opportunity to invest (whatever amount of) new money and get your part of shares for that.

When you chose the 30% payout it would also be 30% fiat payout based on the price on december when the coins got frozen. Or you can chose to not-cooperate and see how much money you can actually "sue" from the old owner...maybe few % or so at its best. You have to decide between crappiest solutions, but like in my case, i also have limited resources to invest into this project and also other investors (new) capital is limited, as i now tried to look for investors many weeks now and it is not easy to pull "new" money into this bankruptcy project at all. This is now the compromise we negotiated in long "night" discussions.

 When old coins would give 3 times more shares than no one is investing and thats it. This is definetly NOT a good investment for new investors, it is necessary to make compromises.

Since you want to be "passive" investor, it might be better to chose the "cooperate", there you would get your "equal" share of the 50% profits from the new site
