Microsoft REALLY hates Bitcoin:

Bing, DuckDuckGo and Yahoo return search suggestions that are meant to convince you that most people think Bitcoin is a Ponzi.

DuckDuckGo and Yahoo search use Microsoft's Bing for more "accurate" results.

Ironically, Google is neutral while the Chinese search engine Baidu is super bullish with top search suggestions such as "Bitcoin is secured by mining/a digital currency/the future/king"
