What crypto do you believe would be the next to have an ETF if Bitcoin and Ethereum are both approved?

Based on Citadel-backed EDX Market’s initial selection of coins (Bitcoin, Ethereum, Bitcoin Cash, and Litecoin), I would believe Bitcoin Cash (BCH) and Litecoin (LTC) would be the next up. Obviously this might be flawed, but I’m assuming there had to have been discussions as to why those two were selected aside from Bitcoin and Ethereum. Additionally, the Chairman of the SEC Gary Gensler back in 2018 stated that Bitcoin, Ether, Litecoin, and Bitcoin Cash are “not securities.” This seems to be the most blatant piece of evidence these two will be the next up. If I had one last piece of reasoning it would be that both Bitcoin Cash (BCH) and Litecoin (LTC) were forked off of Bitcoin. So if Bitcoin receives approval for an ETF, these forks should have a much easier time than most of the other competitors. Let me know your thoughts and if I’m missing anything worth noting. I see ETFs as inevitable which will grow the space and be seen by a larger audience as a result.
