According to this graph the common bonus for early investment should start from 35% and gradually go down to zero. There is a shift at 3000 ETH due to lower risks of investment after reaching the first goal i.e. soft cap.
I believe the graph you posted applies only to stage 2.
I think the goal for both stages is a total of 13000 ETH:
Stage 1 (pre-sale) of ICO has a goal of 3000 ETH.
Stage 2 (main-sale) of ICO has a goal of 10000 ETH.
I think it is merely coincidental that there is a shift at 3000 ETH in the graph.
As to the bonus, one must wonder where the bonus coins come from? Let's take stage 1 as an example.
The ANN states that stage 1 will offer 250mln tokens (COIN) and will end when the goal of 3000 ETH is reached.
One must assume all tokens distributed during the stage 1 pre-sale must come from the stated stage 1 supply of 250mln tokens.
Therefore to cover the 100% bonus one must assume that of the 250mln tokens available that only 125mln can be sold. The remaining 125mln tokens are reserved so that they will be used for the 100% pre-sale bonus.
The amount of ETH collected remains the same.
With no pre-sale bonus:
250mln tokens
-------------------- = 83333.33 tokens per ETH (average)
3000 ETH
With 100% pre-sale bonus:
125 mln tokens (sold) + 125 mln tokens (bonus)
---------------------------------------------------------- = 83333.33 tokens per ETH (average)
3000 ETH
The end-result is the same with or without the 100% bonus.
-------------
For the main sale it was a little harder to calculate due to the variable bonus. But fortunately we don't have to worry about the bonus because as we saw above it doesn't affect the end result:
500 mln tokens
---------------------- = 50000 tokens per ETH (average)
10000 ETH
Final summary based on stated goals and available supply at each sale stage:
Pre-sale: 83333.33 tokens per ETH (average)
Main-sale: 50000 tokens per ETH (average)
I specify (average) next to all my results because one must assume that deals will be made with large investors and will ultimately decrease the tokens per ETH for smaller investors, but I would think this is pretty normal. All I know for sure is that if I had 300 ETH or even just 30 ETH to invest you better believe I would negotiate a great price.
Everything I said might be completely wrong as I don't know much about how ICOs operate so please correct me wherever needed.
Thanks! And I think this is a great project, with or without a pre-sale bonus..
Very interesting info ) But for real see bonus formula on ICO page.
Info for all:
Now we at pre-sale. If you interesting - please fill the form: https://goo.gl/forms/Y6mnLjv9oUdoGIjf2
for convenience - please specify your e-mail and ETH address
Purpose of pre-sale:
In addition, the main task of carrying out Pre-Sale is to expand our budget for additional marketing, advertising, preparing additional materials, tracking lists, articles, videos and conference speeches. And as we can release a finished product earlier.
We estimated and planned to gather at the pre-sale about 300-500 ETH and after it start main ICO.
How to invest:
For investors, we use only Ethereum, since this way guarantees the transparency of all bonuses and participants through a smart contract that will be launched on the main ICO.
1. You fill the form
2. After a while we will send the ETH address on your contacts from form
3. After it you can invest in presale for take bonus 100%
