But what does this mean? Compare it to a gold ETF.
The government wants to control the market. They will do this by taking over the exchanges. One of the things they want at this point, is to force all crypto wallets to apply KYC. They hate the aspect of anonymous wallets. They want to know what you own so they can take it from you or tax the shit out of you.

While the ETF opens the gates to global adoption of BTC, it also means that institutes like Blackrock will do everything in their power to control the market. I expect them to forbid self custody of BTC. You can only buy BTC via their ETF. Meaning they will control all BTC supply. You will not own the BTC by yourself, privately. You will own a contract that says that you own 1 BTC, that they store for you. It is like this with gold. For every bar of gold, there are loads of people who own a contract that says this gold is theirs.

This is how Blackrock rigs all markets and manipulates prices. You are not allowed to own anything. They own it for you and they rig the entire market. If 200 people own the same bitcoin, that eliminates the scarcity which makes bitcoin expensive. They can crash the price this way.

Surely they will have to convince the little people that this is best for them. I expect some terrorist attack of which they will say that it was paid with bitcoin
