The decline looks like a crash because the previous advance is massive, what goes up fast goes down fast. You can see on the weekly chart the decline is a simple correction in the bull market. Either the top wave wave 3 or wave 5, I am not sure. If it is wave 5 the decline is in three waves [A,B,C] and wave C will end lower below 30000. But if the top is wave 3 the decline is wave 4 and it will end soon near current levels.
