If the max purchase is $10k, and 500 are whitelisted doesn't that leave 500+ spots for people that didn't win the lottery?
There are 10.000.000 tokens in the pre-sale, thats 4.000.000$. Assuming all 500 (I've also seen 400 mentioned elsewhere) buys the max amount (which is very unlikely) it would leave no coins. Seems you are mixing $ and tokens.
I guess coins not sold to the whitelist are just moved to the regular sale?
