if i invest 3 eth how many coins i get from you?
The actual amount of coins depend. However, what can be guaranteed is, if you invest right now, you will receive 10% bonus (for investing >3ETH)
AND also 10% for early bird bonus! So that's 20% guaranteed bonus!
Basically, the more investors, the higher than value of each coin will be regardless of the number of coins. So the actual amount of coins do not really matter, however bonuses do matter because 2.9ETH invested 1 month later will receive 20% less than investing 3ETH NOW.
