If we buy in to the logic that at these prices only the weak hands should sell out of fear, because the price is so low and a recovery is bound to come along, then surely there is only a finite number of these people that are willing to sell at such 'low' prices. You would assume that most people with a willingness to sell around 10k would have already done so, so why do we keep having more and more people selling and pushing the price down?
Weak hands aside. There's two very big reasons why it can keep going down.
The first which no one has responded to you about yet is the derivatives market. Now that people can "short" BTC through forex platforms etc they can make money from selling before buying. There's no loss to them if they're pushing the market down, on the contrary it's where their profit comes from, the lower the better for them.
Second reason is the fact that there are still huge amounts of people (prob the majority) that are way way ahead still, like at 2x or more if they bought pre December. That's a hell of a return still even if they do pull out now. No other market will they see that return in such a short time so they haven't lost if they sell, they just didn't make it to the moon. Stratosphere is acceptable to them.
