Microsoft co-founder Bill Gates has revealed his smartphone operating system of choice in an interview held on the social media chatting app, Clubhouse.

As Gates has previously mentioned, he uses an Android smartphone rather than an iOS device, preferring the "flexibility" of the open-source operating system versus Apple's proprietary competitor.

Bill Gates Is an Android Man

In an interview with CNBC and NY Times journalist Andrew Ross Sorkin, Bill Gates elaborated on his smartphone operating system of choice, stating that "I actually use an Android phone."

However, that's not to say Gates hasn't played around with an iPhone, as you'd expect from one of the world's richest men and technology thought leaders.

Some of the Android manufacturers pre-install Microsoft software in a way that makes it easy for me. They're more flexible about how the software connects up with the operating system. So that's what I ended up getting used to. You know, a lot of my friends have iPhone, so there's no purity.

Now, the eagle-eyed among you will notice that Bill Gates and Andrew Ross Sorkin talked on the hottest app of the year so far, Clubhouse. The invite-only audio social media platform is currently only available on iOS, meaning Gates probably has an iPhone or iPad to hand.

In fact, on that matter, Clubhouse co-founder Paul Davidson joined the interview briefly to chat to Gates and Sorkin, confirming that an Android version of the app remains one of the top priorities for the rapidly expanding platform.

Bill Gates Isn't Keen on Bitcoin, Either

It has been a talkative week for the ex-Microsoft chief. In an interview with Bloomberg's Emily Chang, Gates cast aspersions on the viability of Bitcoin for regular investors, questioning Tesla founder Elon Musk's bullish approach to cryptocurrency.

Elon has tons of money and he's very sophisticated, so I don't worry that his Bitcoin will sort of randomly go up or down. I do think people get bought into these manias who may not have as much money to spare. My general thought would be that if you have less money than Elon, you should probably watch out.

This comes a week after Gates said in a separate interview that he has a "neutral view" on Bitcoin and that it can "go up and down just based on the mania or whatever the views are."

Elon Musk has posted several tweets in recent weeks regarding his Bitcoin positions, bolstering that stance after purchasing $1.5 billion worth of Bitcoin for Telsa. Furthermore, Musk has tweeted support for the meme-cryptocurrency Dogecoin, sending the price of the useless cryptocurrency soaring on multiple occasions.

Musk's repeated tweets regarding both Bitcoin and Dogecoin appear to have a strong effect on the cryptocurrencies' price, given his 40 million Twitter subscribers. After announcing Tesla's substantial Bitcoin holdings, the price rocketed up 50 percent, earning Tesla an instant $750 million windfall (only actualized if sold).

So, you want to be like Bill Gates? Go and buy an Android smartphone and sell all of your Bitcoin. Of course, having a $150 billion fortune probably helps, too.
