The answer to the first question is yes, there exists such a trend, however, does it have a real statistical power? I don't think so
the thing about bitcoin price rise at this time is that market is ready and eager for the rise. which means there are lots of investors waiting eagerly with lots of money for any kind of signal so that they can start investing in bitcoin again. as you can see the volume has not been that high and people have been confused and scared for the past couple of months because of things such as ETF,... and the possibilities they have.
this means if a rise starts then it won't be needing that much time to become big. we can see $10k+ within two weeks even!
although I think we are going to see a slow rise to $10k and then shoot up from there. but that is another discussion.
