Day 13.89 - 27.78, reward is 12.50k for a total supply of 375 000 000 coins (53%)
Day 27.78 - 55.56, reward is 6.250k for a total supply of 500 000 000 coins (71%)
Day 55.56 - 83.34, reward is 3.125k for a total supply of 562 500 000 coins (80%)
Day 83.34 - 138.9, reward is 1.500k for a total supply of 622 500 000 coins (89%)
Day 138.9 - 277.8, reward is 0.750k for a total supply of 697 500 000 coins (100%)
