Code:
const uint64_t premine = 9200000000000000000U;
https://github.com/pyrex-coin/Pyrex/blob/master/src/cryptonote_config.hCode:
#define COIN ((uint64_t)1000000000000) // pow(10, 12)
On oldchain it was 33.000.000 coins of Total supply and it was cryptonight algo and reward for block was 100 PYX
and in cicrculating supply was about 18mln coins
and users got half amount of old coins now on new chain
SO we need to run and search everyone hey hey here is new pyx yeap?
