OK, so let have a short comparison
To bitcoin and coin fork from bitcoin:
- Transaction are anonymous, untraceable, that means, in bitcoin if you know address/transaction you can find/trace/link to the previous (ex: using blockchain.info) but you cannot do it with EDC. Only owner of the coin can do it.
- It's flexible, you can use another features using hard-fork without changing anything in blockchain (database), It's impossible with bitcoin because it is hard-code.
- CPU/GPU mining, ASIC resistant, so it's friendly with many normal people
- Difficulty target adjusted every block (bitcoin is 2016 blocks), mission curve is smooth (bitcoin: halve for every 4 years)
- And ... many more, please read the cryptonote white paper.
