After 5 week consolidating in the $27K to $31K range, there is certainly room for further upside now if we see an increase in volume. My gut feeling is bit more consolidation, maybe for the rest of the week and into next week, as theoretically $30K should continue to act as some short-term resistance. That said, we saw what happened last month at $25K after price re-tested this level for the second time, it broke through with ease with enough volume. Hence whether we imminently break through $31K will remain volume dependant imo, especially while price is bullish and not yet overbought on Daily time-frames.
I think a pull back to 23k could be disastrous for BTC as it would mean going back to a range where there was a lot of resistance at 24k - 25k. BTC shouldn't lose what it has gained and more importantly it shouldn't lose mometum. I'd rather see it keep chipping away at 30k then go back down to 28k than a huge pull back which could mean back to bear territory.
Although it would be a relatively severe correction if price returned to $23K (at -25%), I wouldn't call it disastrous. It'd likely put an end to the immediate uptrend, but we've already seen price correct -20% from $25K to $20K and continue the momentum immediately after. Call it luck or a bit fortunate (I think I would), but it was far from a disaster. The further price rises, the deeper the corrections price can handle imo.
The other reason I think going below $25K wouldn't be the end of the recovery overall is that although it acted as resistance twice before, there wasn't a lot of volume there. Hence when it did break to the upside, it didn't take weeks on end to break this resistance, only a few days. Whereas there is a lot of accumulation volume at $23K, somewhat untested as support, that'd likely be strong support (as $20K was).
There is also the bullish trending 20 Week MA that's rising (which previously supported price around $20K), now at around $23.5K and the 50 Week MA that's flattening out in a more neutral manner around $22K. Once the 20 Week MA reaches around $25K in the next few weeks (with price above) I'd probably say a pull-back to $23K wouldn't be as bullish, but right now it'd look like a normal correction to me still.
To be honest once $30K was re-tested I wasn't expecting it to move to new highs overnight. Similar to breaking $25K, there is often a sharp pull-back in order to confirm support before breaking through resistance. Even if the resistance is shorter-term, it's still a distribution zone from back in May last year, almost a year ago now, so remains very relevant. It did pull-back a bit quicker than I expected, but ultimately confirming $28K as current accumulation and support level is a lot healthier than continuing to the upside when price is getting overbought on shorter-term time-frames. It also shows the weakness of bears right now.
Now the advantage the bulls have is that price is at $29K as of typing, no longer overbought and instead text-book bullish by most metrics, not forgetting that $28.5K was also previous resistance that is effectively being broken for the second time now after the move earlier in the month. At current prices the bulls definitely have the upper hand, unless bears can increase the selling volume.
