Next gen cryptocoin thoughts

[totallyG]

Hello

Lets face it, bitcoin is the only usable CC today. It it the only currency that can be used in stores and exchanged to money.
All other currencies cannot be used directly because they have no platform.

I have been thinking about what I think the next generation of cryptocoin will be.

Mining
-No coins are created as reward
-Miners earn the fee
-Every node/client is a miner (one walletid may run many miners)

Decentralised and fair
-The difficulty of the transactions are lower. A transaction takes less than a minute.
-The size of the transactions have a maximum limit.
-Runs well on gaming computers (11GB GDDR5) and as well as smartphones and RPi (256kB L3 cache)
-Transactions will be validated on say 10 different nodes/clients spread in different geological zones

Platform (fack paypal and ebay with their 20% fees)
-A marketplace similar to ebay is available in many languages (russian, chinese, spanish, english etc)
-Similar rating system, no buyer/seller protection, history based. Possible to ban bad persons as a community.
-An ad costs a fee that is given to the miners and community

Replacing VISA
-Hardware terminals can replace VISA with much lower fees

Exchange
-Real currency is exchanged for the cryptocurrency.
-Mirror a real currency rate in the begining then let the market control the value

What do you think about this?
