Brian Armstrong is a big boss of Coinbase, which is a place where people can buy and sell cryptocurrencies, like Bitcoin. He said that if Bitcoin ETFs (a type of investment) are allowed, it would be very good for his company and everyone involved. He thinks this because many people want to invest in Bitcoin through these ETFs, and Coinbase can help them do that. Read from source...

1. The title is misleading and sensationalized. It implies that Armstrong hailed Bitcoin ETFs as a win-win for Coinbase exclusively, while the rest of the article mentions other benefits such as attracting institutional investors, increasing trading volume, and growing custody assets.
2. The article uses vague terms like "preparation" and "launch" without specifying what they refer to or when they occurred. It is unclear if these are related to the recent approval of Bitcoin ETFs in the U.S., which happened in November 2021, or some other event.
3. The article relies on a single source for Armstrong's quotes, without providing any context or additional information about his statements. This makes it seem like Coinbase is the only player in the cryptocurrency market and that its success depends solely on Bitcoin ETFs.
4. The article claims that Coinbase custody has 90% of the 36 billion in Bitcoin ETF assets, without providing any evidence or citation for this figure. It also does not explain how this relates to Coinbase's overall performance or growth prospects.
5. The article ends with a sentence that suggests Coinbase outpaced expert expectations, but does not mention what those expectations were, who set them, or by how much Coinbase exceeded them. This creates a false impression of success and achievement without any concrete support.
