The situation is not entirely clear because some lenders may not loudly announce that they have liquidity issues as early as possible. It seems like a large part of the forced selling by 3AC and counterparties is already over, and it seems like many counterparties don't actually have any collateral from 3AC to sell and must eat the loss.
The answer is probably yes for both questions. These crypto and loan contracts are typically very complex and involve many classes of crypto and physical assets involving many 3rd parties. Therefore it's going to take awhile to untangle things to the point where each party knows their precise risk exposure and ability to take loans out against this exposure/loss.
