Bears never learned the lesson, if you want to kill the rally, prepare at least 100k-150k BTC for the dump, otherwise it's just a fire sale.
You seem to assume that a speculator who wants to sell wants to push price down.
This is mistaking manipulative day-trading for normal speculation. Why would a real bear sell inside such down-spikes? Serious bears either have sold already or sell carefully close to peaks. Why would they suddenly panic after sitting out three days of stagnation?
The people who cause the spikes are either trend-following, using erratic chart signals or plain confused. The same goes for those who buy at 27 shortly after they had chances to buy at 25 -- or even below 22 within the last week!
If you ask me, we have more traders who tend to suddenly change their minds than bears.
OK, what I really meant to say is: we had quite a few dumps of 40-50K size which were also much more fierce yet the market did not yield, if someone saw a slow-motion 10k-20k dump and decided it's time to jump on the boat, then it's tuition fee paid.
I dunno how serious to take the speculation stuff anyway... some people burn all their money while others are just trolling for the lulz. (The trolls win, they get infinite% drama profit.
