Ether falls after Culper Research takes short position
Cryptocurrency Ether ETH= falls 4% to $86.3 after Culper Research reveals short position
Culper says it believes Ethereum's December 2025 Fusaka upgrade has weakened ETH's token economics
The Fusaka upgrade increased Ethereum's Layer-1 gas limit from 45 million to 60 million units, expanding block capacity
Culper's report also claims the creator of ETH, Vitalik Buterin, sold over 19,000 tokens in February, more than he had pre‑announced
The news of the short position comes as the broader crypto market remains under pressure
Bitcoin BTC= fell as low as $60,000 in February, but analysts say prices might have now hit an inflection point after the recent bear market
Meanwhile, ETH, which has a market cap of about $250 billion, as per CoinMarketCap, is down 30% YTD
