Something doesn't add up here with TAJ coin. It says there are 900,000 POW blocks, with a block reward of 99 for the first 300,000, 66 for the second 300,000, and 33 for the third 300,000. That adds up to 59,400,000 coins. But the dev claims that there are only 36,900,000 coins for a Max Supply. What is going on here?
OP actually says "PoW reward: 66 TAJ (after block 300k)" ....
You must have noticed TAJ is PoW/PoS. Last block 173158 was PoS. Current TAJ supply 9,630,215 TAJ.
So we are not talking about PoW reward going from 99 to 66 TAJ after 300k PoW blocks but after blockheight 300k.
Out of last 1000 blocks, 45.7% where generated by PoS miners/stakers
