This is good for Bitcoin. Institutional investors and professional money managers control 33% or 50 trillion or so of assets in USA and most of them buy Blackrock stuff, this might be better than good. Canada and other places also buy Blackrock Stuff. To shrug your shoulders is ignorance - Blackrock isn't just some ETF company, it's the worlds largest. I look at this as a huge rubber stamp. The SEC is going after money launders, tax evaders and those who assist them. They aren't after Blackrock or some decentraliezed blockchain.
