I'm sure many of the seniors in this forum know more about what happened and what will happen, therefore I beg the seniors to give a little knowledge and experience to us newbies, Really appreciate your discussion, Thanks.
You do not have to beg for knowledge here because that's what this forum made for. And if you still have go beg then the purpose of this forum will vanished. You just have to ask it and wait for the answers.
My answers are, When the US authorities sued Binance and Coinbase, the time was around 1-5 June of 2023 and when the institutions like Block Rock and others applied for ETFs then the time was around 14-15 June 2023. As you know the first institute was Block Rock and after it, other organizations started to applied.
Purpose of mentioning the dates is, US wanted to eliminate the competition from US region that's why they eradicate the existence of Most famous exchanges from their territory and after the next week they started to promote and adopt crypto as well which has led many organizations to adopt it too. Just like Block Rock did. Even the US has announced their own Exchange which is yet to come.
And for your second query about pump and scarcity, you are totally right and that's why the price of BTC had increased due to high demand and less supply. As when the adoption of Crypto is being supported in US then the demand increased and due to the scarcity factor of BTC, the price of it also increased.
