Bitcoin, Ether gain; traders cautious as U.S. regulator goes after NFT firm

Bitcoin and Ether gained marginally on Tuesday afternoon in Asia. Most other top 10 non-stablecoin cryptocurrencies gained, except Solana and Tron, with Polkadot leading gains at almost 3%. The Forkast 500 non-fungible token (NFT) Index dropped as the U.S. Securities and Exchange Commission (SEC) charged Los Angeles-based media company Impact Theory for offering and selling NFTs as unregistered securities.
