Why Bitcoin can not cross 10k $?
Round numbers like $10k are always tricky to pass - first of all is kind of psychological barrier and most people are setting some sort of "sell goal".
You see - when bitcoin's price is approaching 10k traders would like to collect the profit by selling coins. That is why it is harder for any coins to reach certain price threshold.
But fret not, we will get to 10k and far beyond that - we entered a solid bullish market, so until some random negative news will hit us - we are fine.
On the other hand, all those traders who've been around for the past half year will have already noted this psychological level and many as well would have bought in exactly around that price point - thinking that this was going to be a solid floor for BTC. That didn't turn out to be the case after all, so I'm expecting a substantial amount of sell orders at or around a simple 10% mark ($11k or even 11.5k), so I'm pretty sure that would be the tougher line to break should BTC cross 10k this month (or even today by the looks of it). Future markets also seem to indicate the same thing.
i say it will all depend on how much money is going to come back to bitcoin market and be invested back in it. i believe there is a large amount of money that has been waiting on the sidelines watching this trend to shape up and to become surer before they jump in.
and there is also the FOMO buyers that we should never forget. so with all that buy power price may shoot up after the $10k.
