Story

What the post asked, what the answer turned out to be, and what the chain says happened. The record below holds the data.

Price 2N

July 6, 2019. One day before Tanabata, 7/7, when the block 77 answer of the first run comes out. The question is Price 2N. Format [solution], digits e83. "Relatively easy", says the author.

Nobody solves it. With 77 coming, the author forgets the hint. Again.

Hint 1: the author uses it quite a bit here. Atbash, then. Hint 2: Atbash makes this price MM. On the foldover N sits right under M, so 2N is MM. Price and MM? Mayer Multiple, the price over its 200 day average.

u/Quantris knew the indicator from r/bitcoin and still overthought it. They tried actual values of the multiple first. Then the two words. The claim confirmed at 04:08:18 UTC on July 9, over two and a half days after the post. u/JDScreesh had been searching "Price" and "Prize". Fair, English is hard.
