The only thing which still gives hope is the fact that the all the coins are still intact in their respective addresses.
Does it makes any different at all? He control all the address so he can withdraw them anytime sooner, he probably just letting all this cool down before he decided to transfer the coins out. The only things that gives hope will be the dox threat from tecshare, if he is wise then he will reconsider scamming
At this point I don't think it matters who believes me or not.
If I can't restore access to my wallets to return everyone's funds, or the hacker succeeds in transferring the coins out of the escrow wallets then I will compensate everyone out of my own pocket at the best of my abilities.
would be nice to know when are you going to do so
