Definitely possible that Ethereum could surge past Bitcoin, especially considering the drop in supply and it being less inflationary now.

But In 2023, it's difficult to say exactly what the market will look like at that point. However, based on current trends, it's likely that the cryptocurrency market will continue to grow and evolve. I may see the emergence of new technologies and platforms, as well as increased regulation from governments.

I think, it's always a bit unpredictable with these markets, but I think there's a chance that Ethereum could reach new all-time highs like you mentioned. So, you might not be wrong at all, but you know, only time will tell!
