On Monday, Twitter's iconic blue bird logo was replaced with the shiba inu dog image associated with the Dogecoin cryptocurrency. This change appears to be a late April Fool's day prank orchestrated by the platform's CEO, Elon Musk, who tweeted a meme about the change and shared screenshots of an old conversation where a user asked him to buy Twitter and change its logo to the Dogecoin's mascot.

Bitcoin is the first true cryptocurrency, it was created in 2008 by Satoshi Nakamoto and since then has become extremely popular. Over $8 billion is invested into Bitcoin today, and there are over 60,000 Bitcoin transactions per day. Just about any product or service in the world can be bought with Bitcoin. The popularity of Bitcoin has led to numerous alternative cryptocurrencies, which are essentially copies of Bitcoin with some unique attributes.
