Yep not a long time ago BlackRock was calling Bitcoin a toy for money launderers. It's funny how these giants with endless vulture funds hoarding massive amounts of property taking advantage of people that cannot pay the bills go around acting as if they have higher moral grounds. These guys are money making machines and couldn't care less.
For now they are allied with the USD and it benefits them calling Bitcoin a scam for criminals, but once the USD starts cracking and they feel some fears of systemic risk they will look at ways to mitigate this and will not hesitate to buy a bunch of BTC.
If you can't beat them, join them. Definitely seems like that is what is happening here. For years, many people, regulators, hedge fund managers, etc. have been calling BTC a scam, Ponzi scheme, worthless, so on and so forth. Bitcoin has consistently defied the odds and soared higher and higher. It's good that these people are starting to realize that "hey, maybe BTC is actually worth something and it's here to stay" FINALLY.
What's exciting is that BlackRock alone manages $6.3 trillion dollars in assets. Imagine if they diversify 0.002% of their holdings into Bitcoin. That alone would increase Bitcoins value significantly. This is just one asset management group out of the countless asset management groups out there. As more and more join in the value will only keep climbing (metcalfes law/network effect). This is just the beginning of Bitcoin finally becoming a legitimate asset.
