Bitcoin (BTC-USD), bitcoin-exposed stocks, and other cryptocurrencies made hefty gains in Thursday morning trading. Bitcoin increased to ~$47.1K (7:26 AM ET), gaining from $45.4K, its price soon after the Securities and Exchange Commission greenlit 11 bitcoin ETFs on Wednesday afternoon.

Ethereum (ETH-USD) jumped 10% to $2.65K. That could be the next crypto to get the SEC's blessing for ETFs. The SEC has deemed both bitcoin and ether to be commodities, rather than securities, making them easier to pass regulatory hurdles. SEC Chair Gary Gensler has stated that he considers most cryptocurrencies to be unregistered securities.

Other cryptos on the rise this morning are: staked ether (STETH-USD) +11%, cardano (ADA-USD) +17%, XRP (XRP-USD) +8.9%, solana (SOL-USD) +7.5%, avalanche (AVAX-USD) +14%, and polkadot (DOT-USD) +19%.

Note, though, that Gensler stated the approval of the ETFs "should in no way signal the Commission's willingness to approve listing standards for crypto asset securities."

Most bitcoin miners and crypto-exposed stocks are also making some big moves in premarket trading. Bakkt Holdings (NYSE:BKKT), which runs loyalty programs for bitcoin, jumped 10%; crypto exchange Coinbase Global (NASDAQ:COIN) rose 6.2%; and MicroStrategy (NASDAQ:MSTR), the world's largest holder of bitcoin, gained 5.1%.

Action in bitcoin mining names: Bit Digital (NASDAQ:BTBT) surged 11%, Greenidge Generation (NASDAQ:GREE) +10%, CleanSpark (NASDAQ:CLSK) +7.8%, Hut 8 (NASDAQ:HUT) +9.3%, Bitfarms (NASDAQ:BITF) +9.0%, Marathon Digital (NASDAQ:MARA) 7.2%, Hive Digital Technologies (NASDAQ:HIVE) +8.8%, Riot Platforms +6.5%.

Some 10 of the ETFs that the SEC approved will start trading on Thursday. The 11th, the Grayscale Bitcoin Trust (OTC:GBTC), which is converting to an ETF, edged down 0.1% in premarket trading.
