I sure hope it takes ONLY 2 years. I sure hope the market can bounce back. I'm getting more and more pessimistic right here, because many people claimed that it's gonna bounce back after Chinese New Year (nothing happened). Some are now saying it's gonna bounce back after the 17th of April (due to tax selling).
Two years is absolutely crazy prediction. No one knows what is going to be in two years IMO.
I bet that by the end of the year market will be higher than the last peek.
