How many?

Compare with Steem.

If the ratio is less than 100:1 I'd be surprised, and will likely very rapidly expand to 1000:1 or 10000:1 if not higher.

The launch of Steem is nothing like the launch of Darkcoin anyway. They told everyone exactly what they were doing, even on the original thread, and the plan to mine 80%, give away 40% and sell 20% to fund development was and is on their web site (steem.io). Darkcoin's launch was and is an opaque "accident".

I was following the original thread and I mined both before and after the relaunch. If I had wanted to I could have easily put thousands of miners on it and competed with them. I didn't because I recognized they had a coherent plan for what they were doing and if I undermined their plan they would abandon the project or more likely relaunch it another way, leaving me with worthless coins.
