how is the block reward decided?
Depends on the popularity. The more people mine CASH, the reward is smaller.
Haha feels weird but okey thanks

This will be a coin that can worth more then $6 per CASH.... now reward is still pretty high, but let the network hashrate increase to 2,000Mh/s then rewards will be close to 10 per block or 14400 coins per day, then you can understand that this one will be huge...
