all in all 143 BTC invested and about 100 BTC left. did MP prove to you that they still have the 100 BTC?
I don't think MP were claiming to be solvent are they? If they were solvent they wouldn't need to issue a debt token; they could just pay people back.
Maybe I'm misreading, but I thought they claimed they were solvent and the "debt tokens" were for the bonus funds they promised investors who took a bath when MP got hit so hard.
For example, in the Maiden situation, he would get his 100
BTC right now and debt tokens for the 43
BTC +2.58
BTC for every year he's been invested.
