To add to that, even the original paper written with 1999-2007 era SDRAM/DDR/DDR2 is not optimistic about the scenario of a machine that was already powered down at regular operating temperatures:
with the fastest exhibiting complete data loss in approximately 2.5 seconds and the slowest taking an average of 35 seconds
And that only got worse with more advanced RAM, not to mention that they lost almost all of the data far quicker than that with only a couple % of bits surviving that long. For all practical intents and purposes, cold boot against an already-powered-down machine is a myth, the cooling has to be applied while it’s on.

Another choice quote from the original IGN interview that this is from:
Guy got talked into the whole blockchain NFT crap so hard that he’s still trying to make it happen, as if it was ever a desirable thing that the best way to get some kind of gear or cool cosmetics in game A involves playing game B instead.
