Should have been in bull by now if all these ASIC miners are selling at a loss.
So far, all the bears are fat and happy.
There will need to be some short squeeze to kill a few bears before any bull run.
They could just go and close their shorts, without being margin-called or their stops being hit! This is not a game of "chicken" or who can hold on to their position the longest. Many bears are actually quite smart - they don't clong to a bullish sentiment, but rather trade the market and try to make a profit, even if the price is going down. If the market changes, they change their strategy/position - it's actually not something to be ashamed of, at all!
It's more realistic to say someone is bearish or bullish than to call them a bear or bull. Few people are permanently one or the other.
