Statistics, Statistics, Statistics - Calculate Rarity & Popularity By ID, By Pose, Fur, Face, Facing & More - Inside the 25 440 MoonCat Population

Any idea of how much will worth mooncat in 6 months?

No idea but mooncats is 1/20th the market cap of crypto punks, and crypto punk whales are selling punks to bag hundreds of cats from paper hands. I HODL! [You HODL! We HODL! Let's corner the market and pump up the floor price!]

Mooncats are off to a good (re)start I think... floor hit 1.7 in like 2 days showing us what's possible.

Moon, cats, pixels, colors... what could go wrong?

Big support line at 0.4 broke, we are finding new local lows at 0.3, but there is no convincing strength in reaction here either. Could go lower, levels like 0.2 or 0.1 are now possible.

Crypto collectibles are all about rarity - the more rare the type or id of a mooncat the more valuable the ~24x24 pixel art in theory.

Let's use the mooncatrescue.csv dataset in comma-separated values (CSV) format that houses in blocks of a thousand mooncats each (e.g. 00.csv, 01.csv, 02.csv, and so on) all the 25 440 mooncats for more insight into the population.

The data records for cats incl. id, palette, design, pose, facing, face, fur, color, hue, row and mint serial number, rescue block and timestamp, and more. Example:

row, id,           palette, design, pose, facing, face, fur, color,    ... mint
0,   0x0000020886, Normal, 0, Standing, Left, Smile, Solid, Blue,       ... 2679
1,   0x000002f63e, Normal, 0, Standing, Left, Smile, Solid, Teal,       ... 13869
2,   0x000004683b, Normal, 0, Standing, Left, Smile, Solid, Teal,       ... 24457
3,   0x0000048998, Normal, 0, Standing, Left, Smile, Solid, Cyan,       ... 22386
4,   0x000006ce5d, Normal, 0, Standing, Left, Smile, Solid, Teal,       ... 7933
...

Let's read in the dataset:

require 'mooncats'

cats = Mooncats::Dataset.read( './mooncatrescue/*.csv' )

puts "  #{cats.size} mooncat(s)"

printing:

  25440 mooncat(s)

Let the mooncat helper do the heavy lifting :-). As a bonus all mooncats get wrapped into easy-to-access structs. Example:

cat  = cats[0]
cat.id            #=> "0000020886"
cat.genesis?      #=> false

cat.design.to_i   #=> 0
cat.design.pose   #=> "Standing"
cat.design.facing #=> "Left"
cat.design.face   #=> "Smile"
cat.design.fur    #=> "Solid"
cat.invert?       #=> false

cat.hue           #=> 237
cat.color         #=> "Blue"

cat.mint          #=> 2679
cat.block         #=> 4244865
cat.timestamp     #=> 2017-09-06T15:03:43+00:00
cat.year          #=> 2017

Popularity & Rarity by IDs

Let's calculate popularity & rarity by ids. Let's find all James Bond mooncats where the id starts with 007 or with all zeros 000 (x3) or 0000 (x4) or 00000 (x5).

counter = Hash.new(0)      # a hash (table) - let's (auto-)default to 0 for values
cats.each do |cat|
  case cat.id
  when /^007/        then counter[ '007'   ] += 1
  when /^000[^0]/    then counter[ '000'   ] += 1
  when /^0000[^0]/   then counter[ '0000'  ] += 1
  when /^00000[^0]/  then counter[ '00000' ] += 1
  end
end

counter
#=> {"00000"=>10, "0000"=>97, "000"=>1487, "007"=>1648}

Resulting in 1 648 MoonCats (6.48%) starting with 0x007 and 1 487 (5.85%) starting with 0x000 and 97 (0.38%) starting with 0x0000 and 10 (0.04%) starting with 0x00000.

What about the rarity percentage? To calculate use:

def rarity_in_percent( count, total=25440 )
   percent = Float(count*100)/Float( total )  # use floating point numbers
   '%.2f%%' % percent                         # pretty print/format percentage
end

rarity_in_percent( 1648 )  #=> "6.48%"
rarity_in_percent( 1487 )  #=> "5.85%"
rarity_in_percent(   97 )  #=> "0.38%"
rarity_in_percent(   10 )  #=> "0.04%"

Popularity & Rarity by Mint Year (5) - 2017, 2018, 2019, 2020, 2021

Let's calculate popularity & rarity by the year the mooncat got minted on the blockchain:

counter = Hash.new(0)      # a hash (table) - let's (auto-)default to 0 for values
cats.each do |cat|
  counter[ cat.year ] += 1
end

counter
#=> {2017=>3365, 2021=>19682, 2018=>2319, 2019=>71, 2020=>3}

Resulting in five mint series. Let's sort by year and pretty print the result and as a bonus let's calculate the percentage (%) in the total population:

counter = counter.sort { |l,r| l[0]<=>r[0] }
#=> [[2017, 3365], [2018, 2319], [2019, 71], [2020, 3], [2021, 19682]]

counter.each do |rec|
  year    = rec[0]
  count   = rec[1]
  percent =  Float(count*100)/Float(cats.size)

  puts '%d | %5d  (%5.2f%%)' % [year, count, percent]
end

Resulting in:

2017 |  3365  (13.23%)
2018 |  2319  ( 9.12%)
2019 |    71  ( 0.28%)
2020 |     3  ( 0.01%)
2021 | 19682  (77.37%)

What about March 12, 2021 - the Mooncat Rescue Day? What about August 10, 2017 - the Launch Day? or Launch Day+1 or Launch Day+2?

counter = Hash.new(0)      # a hash (table) - let's (auto-)default to 0 for values
cats.each do |cat|
  case cat.timestamp
  when Date.new(2021,3,12)    then  counter[ '2021-03-12' ] += 1
  when Date.new(2017,8,10)    then  counter[ '2017-08-10' ] += 1
  when Date.new(2017,8,10+1)  then  counter[ '2017-08-11' ] += 1
  when Date.new(2017,8,10+2)  then  counter[ '2017-08-12' ] += 1
  end
end

counter
#=> {"2021-03-12" => 19681,
#    "2017-08-10" => 492,
#    "2017-08-11" => 412,
#    "2017-08-12" => 229}

Resulting in 19 681 MoonCats (77.36%) rescued on March 12, 2021 and 492 (1.93%) rescued on August 10, 2017 and 412 (1.62%) on T+1, and 229 (0.90%) on T+2.

Trivia: The Mooncat could get rescued for "free" on March 12, 2021 - paying only the transaction gas fee about $25-35 at the time resulting in a gold rush for miners raking in about $600 000 in a couple of hours.

Popularity & Rarity by Pose (4), Fur (4), Face(4), Facing (2)

Remember mooncats get generated from 128 patterns from 0 to 127 - composed of 4 (pose) x 4 (face) x 4 (fur) x 2 (facing) designs. Let's calculate popularity & rarity:

counter = {
  facing:    Hash.new(0),
  face:      Hash.new(0),
  fur:       Hash.new(0),
  pose:      Hash.new(0),
  palette:   Hash.new(0),
  color:     Hash.new(0),
  design:    Hash.new(0),
}

cats.each do |cat|
  counter[ :facing ][ cat.facing ] += 1
  counter[ :face ][ cat.face ] += 1
  counter[ :fur ][ cat.fur ] += 1
  counter[ :pose ][ cat.pose ] += 1

  palette = cat.invert? ? 'Inverted' : 'Normal'
  counter[ :palette ][ palette ] += 1

  design = cat.design.to_i
  ## note: special formula for black/white genesis cats
  color = if cat.genesis?
            design % 2 == 0 ? 'Black' : 'White'
          else
            cat.color
          end
  counter[ :color ][ color ] += 1

  counter[ :design ][ design ] += 1
end

Resulting in:

Voila! That's it to get your started on calculating rarity & popularity stats on the 25 440 mooncats population.

Need more rarity ideas? Find mooncat twins, that is, mooncats with identicial colors and pose/face/fur/facing. Or how about doppelganger twins, that is, mooncats with identicial colors and pose/face/fur BUT one facing left the other facing right. Or how about siblings, that is, mooncats rescued in the same block? How many sisters and brothers is the max?
