I am aware: NOT NEED NOW MORE CURRENCY DUPLICATES ! but... one QUICK currency (my be is needed).
Worldcoin vs Digitalcoin>
Why I think WDC is better choise:
1. 15 sec. vs 20 (DGC) - WDC mining will stop early.
2. 32 monets vs 20 monets block, the transactions base on DGC will be more bigger.
3. WDC start was early (so WDC "inovator", a DGC "scamcoin"
4. WDC will halfed each 2 years, DGC - 3 years.
5. WDC 4 confirmations , DGC 5 - (Don't forgot, we appreciate this currencyes for their speed)
6. WDC is on BTER.com (my be soon on btc-e)
