Its unfair because Devs are not central bankers.
The developer sets the network. network should be allowed to run its course. If prices drop, devs shouldn't be allowed to cut supply. You might ask yourself why but let me ask you this. If prices were to to rocket to the moon, should the dev be allowed to increase supply?
If your answer is no to increasing supply, then the answer should be no to cutting supply.
It becomes a scam when you tell people "yes there will be 12 million coins over 1 year" then turn around 3 months later and say "just kidding, we are cutting suppy at 3 million". This would force a liquidity squeeze, send the price higher and reward early adopters.
But that is exactly what you want right? Cut the supply after you have had your fill of coins and artificially pump the price? Sorry man. You argument for cutting supply hold no weight. So what if multipools sell coins at market? They control the hashrate, they earn those coins fair and square. If you want to compete with them, get yourself enough hashrate, mine supercoin and hoard them.
If multipools are mining supercoin and dumping, then clearly the price is too high and liquidity needs to be injected. I welcome multipools because if I am trying to buy big blocks of coins, why should I be forced to pay a higher price? This is were multipools are a godsend. while everyone is hoarding, multipools are liquidity providers. They will sell to me. Amazing.
I can provide more points but this should suffice. Its becoming clear that you only care about the price going higher. the only time PoW or PoS should be cut is when there was a clear error in the development of the coin. Two examples would be CENT and NINJA. Clear coding errors that hyper-inflated and ultimately killed the coins. Supercoin is not suffering from that so I don't see any problems with the way things are right now.
