We need DIGITAL currency that BTC currently is not:
- has low latency transactions (seconds at most, scaling problem, transaction history drag)
- is eco-friendly = transactions are near free (minimum payment for watts/others/intermediaries/...)
- the price is fixed (to avoid speculations/currency being a subject of trade instead of tool for trade, maybe price fixed to Basket of Goods?)
+ all the cool features that BTC curently has like limited amount of coins (to avoid inflation), security, validability, decentralization, ...
We need a new solution. BTC is a great start but it is not a solution yet.
