Proposal: AWSCoin, GCECoin, AzureCoin
But I wish that Amazon, Google, Azure, and other cloud computing companies would introduce Coins that you could use to pay for their services. I admit that they would have to develop these coins, and that it would not be trivial, but I think the value would be immense.
I know you can already buy Amazon credit, etc. But they don't work at all like the crypto-coins do. If the Cloud-Coins had a public address that anyone could generate, and a private key you had to use to access your own account, and you could call web APIs to transfer from your account to someone else's... And if you could do it in units smaller than a United States Cent?
Even better, if I could issue a temporary key to give to some service, allowing it to charge me at a specified subscription rate (for instance, "Up to $3 US in AwsCoins, per month"), that I could later revoke when I felt like it...
I just feel there's room for a ton of innovation, here. And the coins would be backed by something real. There'd be no investment phase of the currency. It wouldn't be a Ponzi scheme. The original creator wouldn't have 1/20th of the entire market. We wouldn't be wasting compute power and electricity proving to other computers that we were doing work.
