An "Almost" decentralised currency I've been interested in Bitcoin for a while. I've been thinking I'd like to give it a go and see if I can make my own cryptocurrency, just to see if I can.

I run my own small web hosting company, the main reason why I don't want to accept Bitcoin is its price volatility. I mean, at one point it was worth $1000 and now its worth $315.

I was wondering, from purely an economics standpoint, would a currency in which all payments, transactions etc ... where decentralised work if one key part was centralised.

I'd like to make all clients download a text file once a week. In the text file would a number, and that number would tell all of the transaction verifiers how many new currency units can be created in any 24 hour period.

I would like to use this file to control the rate at which new currency units are created, there would be no overall limit like Bitcoins 21M. The value would be controlled by controlling the number of currency units that can be created in any 24 hour period.

So since I know nothing about economics I was wondering, would this work?
This is the proverbial veggie burger with bacon. There are plenty of people who like veggie burgers. And there are plenty of people who like bacon. But there are very few people who like both.

You have a cryptocurrency that's not run by a government. But it also has a central authority that can inflate it and regulate it at their whim. There are people who like these revolutionary cryptocurrency systems that are not run by governments. And there are people who fear deflation and like  currencies that can inflated as deemed suitable by a responsible steward. There are just very, very few people who like both of these things.

You will have to answer this very hard question -- "Why would I want to use a store of value that lets you tax my stored value as you wish?" And "Why should I use a currency that's not backed by a government and not subject to political controls when I can use currencies that are?"
