Bitcoin plunge… Michael Saylor sees two-thirds of his fortune 'wiped out'

Michael Saylor, chairman of Strategy, has seen his fortune shrink by nearly two-thirds over the past six months amid a downturn in Bitcoin (BTC) prices.

According to Bloomberg on the 11th (local time), Saylor’s net worth was recently estimated at about $3.4 billion (about KRW 5 trillion). Bloomberg reported, “(Saylor) has lost about two-thirds of his wealth since the peak in July 2025,” adding that “most of his fortune stems from his 8% stake in Strategy.”

Bitcoin has remained on a downward trend since late last month, recently sliding into the $60,000 range. According to CoinMarketCap, Bitcoin was trading in the $66,000 range as of the day, down more than 27% from a month earlier.

The selloff has also sharply reduced the wealth of Brian Armstrong, CEO of Coinbase. Bloomberg reported that Armstrong’s net worth has fallen by more than $10 billion over the past seven months, leading to his removal from Bloomberg’s “500 Billionaires Index.”

In addition, the Winklevoss twins, who founded U.S. cryptocurrency exchange Gemini, were dropped from the index. Their wealth fell from $8.2 billion in October last year to $1.9 billion recently, a decline of more than $6 billion over the past four months.
