Pricing for UNICOINs (UCN) is dynamic.
Basically, the more UCN are being bought by participants, prices will increase accordingly.
During Pre-Sale the pricing for 1 UCN starts at approximately 0.0000033 ETH and increases to approximately 0.0000267 ETH - if all 10,000,000 UCN are sold.
The price increase is linear and is recalculated every time a transaction was successful.
Example (on how the contract calculates the price):
During Pre-Sale 1 ETH will start at a rate of 300,000 UCN (PRESALE_START_PRICE) and end at a rate of 37,500 UCN.
Linear factor for Pre-Sale is fixed at 38 (PRESALE_FACTOR).
The price calculates as follows:
PRICE = PRESALE_START_PRICE - TOKEN_ALREADY_SOLD / PRESALE_FACTOR
If 1,000,000 UCN are sold the trade for 1 ETH would then calculate to: 273,684 UCN
If 5,000,000 UCN are sold the trade for 1 ETH would then calculate to: 168,421 UCN
If 9,000,000 UCN are sold the trade for 1 ETH would then calculate to: 63,157 UCN
It is not possible to buy more tokens then the max of 10,000,000 UCN during Pre-Sale.
Every transaction which attempts to buy more UCN then available will be reversed.
