I think that many of these companies and institutions wanted to get into digital assets years ago but they didn’t due to regulations. They didn’t want to deal with non compliance with the democratic admistration and SEC head Gensler which was very anti crypto.
But with Trump in office they know he is pro bitcoin and they got less hurdles to jump thru. Basically they get involved in anything as long as they can turn a profit. So it’s no surprise we are seeing more and more of this.
The first Bitcoin Spot ETF application was submitted in 2013 and it's about 10 years before first Bitcoin Spot ETF approvals announced in January 2024. One year before that, Grayscale won a lawsuit against SEC that opened a bigger gate to Bitcoin Spot ETF approvals and BlackRock smelt that great opportunity, then took advantage of it to submit their Bitcoin Spot ETFs.
The remaining things are famous, BlackRock enriched their successful rate of their Spot ETF applications and Bitcoin community and market have first ever Bitcoin Spot ETFs in the USA.
Gates have been unlocked gradually over time, from first physical peer to peer trade (bitcoins for pizzas), first centralized exchange, first Bitcoin Futures, and first Bitcoin Spot ETFs. We will witness more Bitcoin adoption growth in the future, I am strongly believe in Bitcoin's bullish future.
