40% in a sense that Bitcoin has been approved and that can influence the decision, 60% of being declined due to probably many setbacks and factors that will be figured out by SEC if these are like the first few applications.
SEC chairman Gary Gensler used to call Ethereum a "security". I wonder if that will change now that Bitcoin spot ETFs were approved last week? Everything will depend on how the ETH network is structured. If it stays centralized, it'll be classified as a "security". Otherwise, it would be classified as a "commodity".
I doubt Gary's stance towards ETH will change especially when the cryptocurrency has a PoS mechanism. It's largely controlled by whales and big exchanges like Binance and Coinbase. We'll see what happens in the long run. Rest assured that if ETH spot ETFs are approved, market prices will rise like crazy. At least, in the long term.
