This comment shows a lot of ignorance. An ETF is just a "wrapper" for an Underlying Asset. Bitcoin is still decentralized as ever, and will continue to be. This approval just makes it easier for larger financial institutes to access it without having to worry about becoming a custodian, and will likely drive the price up a bit over the next many years.

Bigger picture, the USA has just given Bitcoin the greenlight, and this will have big fiscal and geopolitical implications in 10-20 years.

Irony/sarcasm aside, people buying crypto ETFs from their existing brokerage and retirement accounts would push the price up and in turn make the decentralized network more secure.
