They have a hard cap of $25 mln for 10 mln tokens for the presale+ico. They are also selling an additional 23 mln tokens at market price for public sale. With costs of tokens averaging around $5.5-6 during presale it looks like they're trying to raise $150-200 mln. Pretty greedy for nothing but vaporware atm imo.
The cost per coin ratio will change if they hit the $25 million cap before selling 50k coins. Which most likely will be what happens since ETH is on the rise. This will mean they either burn more coins and give everyone 1:200 ratio which will increase the price of the coin or they divide the 10 million coins out to each pre sale buyer. That ratio would be much higher for example at current ETH price it would be a ratio of 1:400 so not bad deal for the pre sale to get 100% bonus.
Well written answer, thank you
