Forum:Stardust vs 2 BTHs

So player A has a Stardust and Player b has 2 Bottomless Trap Holes set. It is player A's turn and he special summons a monster. Player B responds with BTH and Player A negates it in the same Chain link with Stardust. Can Player B chain the 2nd BTH? I know this is an odd question, but in either case is the timing for the second BTH possible?
