By only changing the block to halve at, you are also changing the max number of coins, going from 19.948.700 up to 20.474.396. You should then change the structure of the reward system and I don't think that changing the rules of the game now is a good idea.
The reward is going to be acceptable now, it was the initial reward of 77 kdc that was completely insane. 1/3 of the coins were mined in less than 2 months. With the new reward system, the coin will be mined up to july 2024.
Don't get me wrong, I don't deny the importance of a secure net hashrate but right now this coin is living on its investors, not on the profit miners. Will those guys turn off their mining rigs after the next halving? No, most of them won't as they are in for the long haul. On top of that, look on coinwarz, the net hashrate of the other coins. They are low as hell too. There are so many alt coins that can be under a 51% attack that the odds that kdc will be attacked are low. I don't say that there is no risk but it's reasonable atm. Why would someone 51% attack kdc for no profit when there are tons of other coins with a net hashrate of 15-30 MHash? It's easier to attack those coins.
There is actually a faction on these very forums that are actively targeting what they consider weaker coins and doing whatever they can to destroy those coins. The increase from 19.9million to 20.4million total coins is only about 3% when all is said and done so I don't think it will be a very big deal in the long run. However, if we lose half our net hash again (like we did during the last 2 halvings) it isn't going to take very much for someone to implement a 51% attack (around 10-25MH if we drop from the current 50-100MH we have been seeing the last week or so.)
We really haven't seen any benefit at all from the last two reductions in rewards (I know a lot of factors play into this but we have been on a constant downward slope) so it doesn't seem prudent to me to continue on with the next one when our net hash is already very low. I think we can easily survive a 3% increase in total coins, however if someone were to 51% (even if tberes only a 1% chance this happens I still think its worth waiting on the next block reduction) attack us I don't see anyway we end up surviving
look dude ..... There is 1 thing AND ONLY 1 thing that make hashrate increase .....
.. not community
..not belivers ...
