I get your idea regarding even smaller amounts of sats become worth quite a bit with where things are heading. And I mostly agree on the long term perspective you have on things.
And I really liked the 1g funded bars, quite unique pieces and they look really good for that tiny size.
So with a larger 3g bar I expected to also see a higher denomination, 3x 7.5x would be 22.5, so why not 25k or 30k is what I am saying.

Are there still 150k sat bars available and if so what's the pricing? And how about the copper 125ks?
