How does IPO work. If only these 2 investors pay do they share 2 million or is there set amount of icoin per btc
Use this formula:
Reward = Stage amount * (Personal Investment / Total Investment)
For eg. if there were only 2 investors, investor ID 2 would receive:
Investor ID Amount Invested
1. 0.99 BTC
2. 0.48 BTC
Reward = 2,000,000 * (0.48 / (0.99 + 0.48)) = 653,061 ICN.
