Please check your Whitepaper, token price = 1 satoshi? and there are only 80 000 000 VIS. Your cap is 0.8 BTC?
A lot of things are suspicious here to say the least. They don't even get their metrics right and this should be a red flag for a lot of people.
Please download our Whitepaper and see for yourself! Do not draw conclusions without understanding.
The whitepaper says initial token price of 0.000001 BTC and total of 80,000,000 VIS tokens for sale, so around 80 base BTC is aimed to be raised?
The 'coefficient of token price change during one round' and 'period of price change, for each tokens' concepts are very confusing. How do they affect the token price during the sale?
The 'coefficient of token price change during one round' shows how many times the price of tokens will increase after a certain round.
In the first round in the first stage we will sell 2 000 000 VIS * 100 sat = 2 BTC.
At the second stage, the price will change from 100 sat to 273 sat, which means 2000 000 tokens will be sold at a price of approximately (100 sat + 273 sat) / 2;
This implies 2000 000 VIS * (100 + 273) / 2 = 3.73 BTC.
In the following rounds, we will get approximately:
2. 5.46 BTC and 7.18 BTC
3. 8.91 BTC and 10.22 BTC
4. 11.54 BTC and 13.01 BTC
5...
All this you can calculate using the data from the table on page 38 of WhitePaper.
The 'period of price change, for each tokens' shows, after how many tokens are sold, the price of the token increases by 1 sat.
