If Bitcoin succeed to hit 12k then anything is possible and rising to hit 15k will be a peace of cake.
Bitcoin, now, is struggling to break the 10k wall, it has been fluctuating between 7.5k and 9.5k during the past two months and it is hard to predict when will be the next phase. This situation may last for another month as it may last for a year, nothing is certain.
maybe we really a big good news so it will make the price pump so high and break any wall. like you said, it still very hard to break the wall of price and not just 10k but to break 9k, it seems it's too difficult and it needs more power to reach that price. so maybe we need to wait for a big good news for bitcoin and many investors is come to bitcoin and push the price to increase.
