Almost all of the bot purchases - as can be seen here: https://imgur.com/a/zVVNfcC - are 13 keys + 13 ref, which rounds to 13.5 -> 14 keys. Meaning that we actually have more sales for a 14 key low end. 13 keys sale was actually the one sale. also cache shows buyer at 13.5 keys ( https://gyazo.com/466125ae410a3251438c00364c754c81 )
