The 3.5 % is not realistic. What if master node to keep? The price will be on the bottom.
What are you basing this on? Why is 3.5% too small? Do you have an actual argument?
There are 960 blocks/day, and 25 KMC/block. If the masternode reward is 3.5%, that is 0.035 x 960 x 25 = 840 KMC/day for masternodes. Why do you think that is too small?
If you have 100 masternodes with a 2000 KMC requirement, then each masternode gets 8.4 KMC/day. That is over 3000 KMC/year. So you turn 2000 KMC into 5000 KMC after one year, with a 3.5% reward (if there are 100 masternodes). On what basis are you saying this is too small?
Please don't argue that it should be 35% just because other coins do that. KMC looks like it is doing something different from other shitclones, so we should try to make it sustainable. If you think 3.5% is too low, provide an actual argument for why. I'm not saying 3.% is the right number, but I'd like to see someone make an actual case for something different.
Well, let's look at some other coins.
INNOVA: 50% reward to MN = 7200 coins per day, 308 MN - 23.37 coin/day.
DESIRE: 20% reward to MN = 2304 coins per day, 268 MN - 8,6 coin/day.
804 coin per day for 200 MN - it's only 4 coin for MN. But I expect more than 200 MN even the cost of each will be more than 0.25 BTC.
Thank you for providing some actual numbers, it will lead to a more productive conversation. I would have two questions in response to your post:
1) Are INN and DSR good comparables? They have gained massive value since their launches, but we don't actually know yet if that growth is sustainable. Are there any 6 or 12 month-old masternode coins that could serve as a better basis for successful masternode reward %?
2) How many masternodes do you think we'll hit? After 3 months (which is older than DSR or Innova) we would have a total supply of 90 days * 960 blocks/day * 25 KMC/block = 2.16 million KMC. If we set the masternode collateral at 2000, that would mean a potential 864 nodes, although in my experience only about 40-50% of masternode coins end up going into nodes (meaning closer to 430 nodes). So, we would need a reward closer to 15% to get 8+ KMC/day.
What do people think of a 15% reward, assuming we think DSR is a good comparable (just for masternode stuff, KMC will actually be a lot stronger than DSR because of the no-premine etc)? Might be a good compromise so that people don't think it's too small, but at the same time it's not giving something ridiculous like 50% rewards for no reason.
May be INN and DSR not good comparables. I compare projects that start this autumn.
We can also look at VIVO: as INN it has 50% reward to MN but this reward is lower - only 10 coins, 3600 coins for nodes.
VIVO started on August, 22, and now there are 510 MN. Coin price is $4.61. Reward - 50%.
INN started on October, 19, and now has 308 MN. Coin price is $4.52. Reward - 50%.
DSR started on October, 15, and now has 268 MN. Coin price is $0.61. Reward - 20%.
All these projects had premine but is this significant for the cost? I think no.
When MN reward is high it is interesting to have masternode and people going not to sale their coins but put them to masternode. I'm affraid the low reward will force people not to lock coins in MN but to sell them and the cost will go down.
