The SEC is reviewing the rule change proposal for the Cboe exchange, mainly to optimize the quoting mechanism for Mini Bitcoin U.S. ETF index options to enhance market liquidity. At the same time, this move aligns with the practices of competitors, indicating that U.S. regulators are gradually relaxing their stance on Bitcoin spot ETF derivatives.

【Chain Wen】The SEC has recently launched a formal review of the rule change proposal for the Cboe exchange. This adjustment mainly targets the quoting mechanism for the Mini Bitcoin U.S. ETF Index (MBTX) options—contracts priced below $3 will have a minimum tick size of $0.01, while those above $3 will be $0.05.

In simple terms, this is an optimization of market liquidity. Competitors’ IBIT options have already adopted a similar scheme, and now MBTX is catching up. Finer trading depth and more flexible pricing are beneficial for market makers and traders alike.

The SEC is now soliciting public opinions, and whether it will ultimately approve depends on the feedback. But from the trend, U.S. regulators’ attitude towards Bitcoin spot ETF derivatives is indeed gradually relaxing.

It's the same rhetoric about liquidity optimization again, ultimately just trying to exploit trading counterparts. IBIT is already up and running, MBTX will be left behind if it doesn't follow the trend, that's the reality.

It's MBTX and IBIT again, these two keep competing endlessly. In the end, the winners are probably still the market makers.

IBIT is already here, and MBTX's follow-up isn't surprising... By the way, can this $0.01 tick size really allow retail investors to truly get some benefits, or is it just another feast for market makers?

watching the tick size game play out... classic regulatory arbitrage theater. IBIT already running the playbook, MBTX just copying homework. but here's the real alpha—when consensus shifts this subtle, that's when the real money moves. SEC greenlighting tighter spreads = institutional confidence signal. sentiment data screaming bullish divergence on this one.
