币界网报道：The U.S. IRS has introduced a controversial 90% deduction rule for crypto gambling losses, sparking debate in the Web3 community. Under the new guidelines, only 10% of gambling losses can be deducted against winnings, significantly impacting crypto-based gaming platforms. Industry analysts warn this could deter casual players and stifle innovation in blockchain gaming ecosystems. Major crypto casinos report concerns over potential user exodus as tax liabilities may now outweigh potential rewards. The regulation comes amid broader U.S. efforts to increase oversight of crypto transactions, with critics arguing the rule unfairly targets decentralized gaming platforms while traditional online gambling remains subject to different tax treatment.
