The agency similarly asked for public comment in June.</p><p>"There's nothing [in the SEC's order] that we're not saying ourselves as an ETF issuer," Ryan Louvar, general counsel at WisdomTree, <a href="https://markets.businessinsider.com/currencies/news/bitcoin-ethereum-etf-sec-gary-gensler-regulation-crypto-2021-07">told Insider previously</a>. "Bitcoin is volatile. It's a speculative asset."</p><p>But the SEC now may be warming up to the view, expressed by many bitcoin fund applicants, that not approving a regulated ETF could present its own risks. In Tuesday's filingsas in previous onesthe agency asked for comment on whether "manipulation concernsare outweighed by quantifiable investor protection issues."</p><p>"I was encouraged by that step, that the SEC is at least taking incremental steps here," said Louvar.</p><p>SEC Chair Gary Gensler has worried aloud that the bitcoin market, as currently structured, offers no real investor protections or any way to prevent manipulation. That has made <a href="https://twitter.com/RonwHammond/status/1414616171782017030">some</a> in the crypto industry bearish on the prospects for ETF approval this year.</p><p><em><strong>Read more:</strong> <a href="https://www.businessinsider.com/what-is-crypto-staking-kraken-product-chief-rewards-tokens-risks-2021-7" target="_blank" rel="noopener">Crypto traders have staked billions of dollars on Kraken over the last year to earn interest.
