Why would you say that its weak? We're talking about billions in trading volumes in the last 24 hours and the market is still unable to make a return. 10k USD might break soon under such a market sentiment. Bitcoin's price has been dropping almost steadily after the peak.
Well, the reason is because I predicted, a few days ago, a bear wave (final one, then going back up) from ~10k - 11k down to test $8k - $9k, and instead the price just went from $9k to $13k.
So based on expectations of one more test at the support level ($8k - $9k), the current move seems very very weak.
If the price goes under $10k, which it might, it's nothing to worry about, in my opinion. It's only if $8k is breached - in that case I'm selling on the bounce. Anything higher than that, and it's buying time.
It's just common volatility we're experiencing due to how thin the markets are. If we had more liquidity available, the market would remain pretty stagnant in times with no developments or other triggers helping the market forward. As long as we don't fall below the recent bottom, which was just over the $9k level, there is nothing really interesting happening. I still expect $13-$14k before the end of next week....
