I wonder if this pump is caused by the fact that we have had positive inflows into spot ETFs for four days in a row (and that hasn't happened in a long time), or if the market reacted to the news about the public announcement of all those US banks/companies that invested billions of $ in BTC through ETFs. Maybe it's a combination of both, but now the question is how long it will last.
The most convincing reason I heard is that it was caused largely of a decreasing inflation (and thus: interest rate) expectation in the US since the last Fed meeting. Basically I think it could have been contributed that stock markets are rallying worldwide, which is usually also a good sign for Bitcoin because it shows that people are willing to invest in riskiear assets.
I think also that the price didn't threaten again to fall under 60k significantly has also contributed. So there is more confidence in the current price level, and fear of another dump under the recent 56k lows are waning away.
I'm however not sure if this all is enough to get a new ATH soon. It could also consolidate again below the old ATH of 69k, but a bit higher (around 65-68k) for some time, but that would actually also be bullish in my opinion. A "quadruple top" in the 71-73k area due to a short and unsustainable spike would be more bearish.
I don't know if it can be seen/verified, but are there sales walls that can show how much BTC is for sale in the $80k to $100k range at the moment?
I haven't found such a wide orderbook aggregator. Most go up to 75k approximately, like on
Coinglass which goes up to around 78k for spot (it goes up to 100k for futures, but there are almost no orders in the 80-100k range). I think for more you'd need an API account directly on the exchanges. But as in the 75-78k area there are already relatively few coins for sale I think that currently that won't be that different for over 80k. I think people will post their orders in this region once we go a bit higher, e.g. over 70k again.
