When the price collapsed after Christmas I tried to get my facebook friends to all buy $100 worth at market price and to buy $200 more if the price went even lower. I called the bottom to the day, price rebounded over 100% in a few days. Nobody listened.
I also told people to buy when the price was low but there is a learning curve which is hard to "jump at the opportunity" with. It takes time and education.
After learning about the willy bot and the false liquidity I no longer advise others to buy in.
I had the same worries, but I decided my worries were unfounded because the price has stabilized around $600. The price would have kept dropping further if the willy bot made the market completely artificial. So regardless of what that willy bot had "accomplished", it is now out of the picture because Gox is down permanently, and the price is stabilized and shows signs of increasing again. So I would suggest you re-look at what you really think the willy bot has to do with today's prices. In my opinion, nothing any more.
