Still, any seller who purchased in the last year and selling now is LOSING money. Bots or no bots, somebody needs to opt to sell and this means this person is either weak handed or a total MORON. All this under condition BTC sold are purchased at one point and not mined. If they are mined, then take a look at my previous comment.
I am agreeing with you - the people you describe as morons, I refer to as sheep - you can see the little trades flooding in on some markets, as some people look at the big red down arrow (sometimes caused by someone selling 0.005 BTC), and press the button that says 'Yes, I am stupid, and I want to sell at the current market price and help to continue a downward spiral, instead of waiting 5 minutes and seeing the trend tick upwards'.
The overwhelming majority of the BTC owners are way up the price ladder, but unfortunately, there are enough useful idiots who will panic sell at market price, that makes the market adopt a bearish attitude.
