"Why not just use bitcoin?"
My personal opinion is the transaction times on bitcoin are too slow for things like e-betting. If I see a match starting in 5 minutes, my BTC isn't going to make it in time.
That's a fair point and very true. I guess the only reason I actually USE alternate coins to to send them between exchanges. Just so I don't have to wait the hour+ to receive them. I guess that's why Fastcoin had its moment in the sun a year ago =p
