The dogecoin systerm is DRYING UP, we need change!---Why Dogecoin's inflation need to be lower than USD's and why PoS is cheaper for running Dogecoin systerm.

1. Dogecoin is like a pool. When you buy something use dogecoin,  you are pumping water out from the pool. Because these dogecoin will be sold for USD. If no new water(USD) come in, the pool will be smaller and smaller till dry up. You use more dogecoin to buy things, the pool is drying up faster. We need new water(USD) in.  How? Why people hold dogecoin but not USD? If you put USD in bank,you get interest.  Dogecoin must be better then USD. That means Dogecoin's inflation must be lower than USD. Else people will sold dogecoin for USD of course if USD is better. Then the pool will be dry up soon! (People hold BTC,because they "think" BTC's inflation is lower than USD. )
 
2. Dogecoin is a systerm to transfer money. It should be cheaper than bank systerm. But Every year 5 Billion dogecoin is paid to run Dogecoin systerm( 7 months later).  It is very expansive! Because most of the 5B Dogecoin will be exchanged to USD to pay the power company and depreciation of mining machine!  If it is so expansive, why we don't use bank directly?  It need and must be changed. Change POW to PoS or something better. Don't wast money on electricity. It means nothing! Let's get a cheaper method to support the Dogecoin systerm. And make some interest for Dogecoin holder!

So my opinion is 1, lower Dogecoin's inflation than USD's. 2 Change to PoS to lower the cost to running the systerm and make some intertest for holder.  Else people will hold USD but not Dogecoin, the systerm will be die.   

Of course, you can't use PoS at the beginning, because no one will accept it. But dogecoin can use PoS now, not every coin have this opportunity. Let's make history and make dogecoin a real curreny.

I am a miner too. I know miner will be Centered to the lowest electricity fee place finally. Because it happens in China now. Then most cost will be the electricity fee. And it is not decentration at last. It will be centred to the Lowest cost miner. It is very dangerous. It is not profect now.

Sorry for my poor English.
