$10,000 is a short-term target. The gap between $8,400 and $10,000 is not very large, but it reflects the confidence of the market. So $10,000 is a breakthrough for the market.
The last time we attempted to break 10,000$ it send Bitcoin all the way back to 5,900$ so I wouldn't be surprised if that happened when Bitcoin decides to continue this rally it currently having, if we want Bitcoin to really be back on the up trend we really don't need to hope in Bitcoin on rushing to close the gap between 8,400$ and 10,000$ as the faster we go to that level the harder we will fall back again. Let us just not hope that we see another crazy price jump one after another, it would really be bad for us.
