Igor Bogdanoff, twin brother of Grichka Bogdanoff, French television personality and the face of countless cryptocurrency, stock market and conspiracy theory memes, has died six days after his brother's passing.

The French presenter, who together with his brother Igor achieved global popularity in recent years as the twins were depicted as mastermind villains in cryptocurrency and stock market memes, has died aged 72, less than a week after Grichka's death from COVID-19, French news agency AFP reported.

Well-known television personalities in their homeland, the Bogdanoff twins achieved global recognition in memes in April 2015 after their photograph went viral on Reddit's /r/WTF subreddit. From there, the twins were picked up by 4chan, where a meme about the Bogdanoffs controlling entire governments from the shadows soon formed.

The twins rose even further in meme popularity among the trading crowd after YouTuber Bizonacci turned Igor and Grichka into villainous puppet masters of the cryptocurrency market in his series of meme videos on cryptocurrency trading. Igor, in particular, is known to many as the person holding the phone in "Dump Eet" and "Pump Eet" reaction images.

According to AFP, the family of the presenter did not wish to disclose the cause of his death.
