Megasat uncommon
The first sat of every millionth bitcoin: a sat number divisible by 100,000,000,000,000. Sat 0 and twenty more, each the first sat of a block.
How a sat qualifies
Sat s is a megasat alpha when s is divisible by 100,000,000,000,000: 1,000,000 bitcoin of 100,000,000 sats. It is the highest milestone tier, so a megasat is never also counted as a centasat, decasat or kilosat.
There are 21 such sat numbers below the 2,099,999,997,690,000 sats that will ever exist: 0, 100,000,000,000,000, … up to 2,000,000,000,000,000. Each is the first sat of a block:
- sat 0 opens block 0 and is mythic;
- the other 20 are plain uncommon, opening blocks 20,000, 40,000, 60,000, 80,000, 100,000, 120,000, 140,000, 160,000, 180,000, 200,000, 230,000, 270,000, 310,000, 350,000, 390,000, 440,000, 520,000, 600,000, 730,000 and 940,000.
The gaps between those blocks grow as the subsidy halves: in the first epoch, at 50 bitcoin a block, a million bitcoin took 20,000 blocks.
Why "uncommon"
The fork's type is megasat_alpha; the site labels it Megasat uncommon, the rarest of Uncommon's sub-categories. The category matches by type, so it includes sat 0, which is never counted as Uncommon.
Its pair
The sat just before each one, from sat 99,999,999,999,999 on, is a Megasat black. Sat 0 has no sat before it, so there is one fewer Megasat black. The site's pair rule counts a Megasat black sold with a Megasat uncommon as part of the uncommon's sale, although Megasat black is the smaller category.
How many
Will ever exist: 21. Mined so far: 21. Extracted, held alone in small outputs: 3. The last one opened block 940,000.
