On a separate note, expected trade volumes should be a factor for Kumala... in terms of how many BTC worth of the coin would get traded a day (that's where he gets his money from alongside withdrawal fees). That could make BTB a good pick since it had 20 BTC of volume yesterday on bter, putting it at the same level of trading volume as TRC for that exchange.
On the other hand, DGC's slightly slower block times greatly reduce orphan rates which lead to a more stable block chain without compromising the "instantaneous" nature of the coin. On a similar note, requiring 5 confirmations @ 20 seconds each rather than 4 @ 15 increases transaction security by about 50%. Additionally, it's lack of a premine period and perhaps the fairest start of just about any altcoin to date has prevented a few ultra early adopters from hoarding tens of thousands of coins which somewhat insulates it from massive dumps that other currencies have experienced that led to their downfall. Further, it has one of the most active altcoin developers of any currency on this forum...this is invaluable.
I take the exact opposite view...I think it makes no sense to support a slightly inferior coin just because it was released a couple days earlier.
DGC being 5 seconds slower doesn't "greatly reduce orphan rates". Everything in your post is FUD and hot air. The only difference between WDC and DGC is DGC is 5 seconds slower to confirm. And there will be 25% less DigitalCoins than WorldCoins produced. That's it.
