ETH does not have leasing system like EDC. If it will be possible to lease Ethereum it would be very good.
EDC has smaller transaction costs.
EDC has blockchain and coin constructor. It is possible to create a minable coins. It is not possible to create minable tokens on Ethereum blockchain.
EDC has higher speed of transactions.
It is only some of the visible advantages of EDC.
And the price of EDC grows more active than the price of Ethereum. Because Ethereum falls. Ethereum lost 21% of the price during last month. But thanks leasing program I earned money on leasing EDC. The price of EDC on 16July was 0,003655. Now it is 0.004358. Even without leasing program the price of EDC grows.
