Most likely this could be the main reason, as investors are running away from banks right now because of the uncertainty, problem majority of them have problems with their liquidity and it takes the government to bail them out.
And with that, investors or even just average joe who have money in the bank might have been withdrawing it because they are afraid that they can't get their money on time and this banks are going to collapse. They are not looking for alternatives to put their wealth 1:1 or even make money thru bitcoin. So it's strong enough reasons for us to see buying pressures in the market for the last 3 days or so.
We all know how untrustworthy banks could be couple with the fear from SVB fiasco are very threatening for investors which might leads them to have an alternatives to secure their asset with digital currency without undermining what happened previously with FTX and Terra, I believe they will learn to hold in a self custodian wallet where they could be in control of their assets rather than any other third party. Likely this could be correct or wrong but I also feel the buying pressure within this few days that is to say there's a good chance of bitcoin creating a new ATH before we could gets to next bitcoin halving.
