one of those crazy buying opportunities

Well done those who hung in there and bought as low as 52c today. It happens every so often and is one to watch out for - panic sellout which completely over does it. It's similar to the panic buys which also occur occasionally and push the share price too high for that moment. Some clever ones pick the top, sell and buy in much cheaper, just as some picked today's low and could make a profit already if they chose to do it. I just sat and watched bemused.
Obviously there are watchers waiting to buy cheaply. They profit from panic.
