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.
