This is a great question. Here is what I can tell you.

First off we have a referral program that can get you an extra 100 coins EVERY time someone uses it.

During presale and the ICO, purchases can receive extra tokens up to a certain limit. We are setting a cap of 10 million tokens to be sold during the presale. During this time, all purchases will be given 30% more tokens. Once the ICO starts, the bonus structure will change to the following:

Phase 1 of the ICO will offer 20% more tokens on purchases on the first 5 million tokens. This is outside of the tokens sold during the presale.
Phase 2 of the ICO will offer 10% more tokens on purchases on the next 10 million tokens.
Phase 3 of the ICO will offer no bonus tokens and a flat exchange rate of 1000 tokens per Ethereum is set.
