If Solana gets approval for this it will be probably the last that counts but in the one decimal percentage, the first approval of Bitcoin ETFs in the US had a real impact, the world didn't even care about the rest, despite the US not being the first, despite talks about HK and Brazil nothing really moved the markets. Now there was hype about ETH and turns out that there is not as much as some anticipated, basically, we're back one step to square one and already things get diluted.
Yeah, you will have Sol ETF, then everybody will say we're going to have ADA, DOGE, LTC, whatever..it would stop mattering as the whole novelty goes down and once the big guys start looking at the revenue numbers they will see so much correlation between them they will just stick with the first ones and throw pennies at the rest.
If somebody thinks news about ETFs will keep pumping the prices forever prepare to be disappointed.
