http://bitmines.orgWelcome to BitMines.org - the one of a kind bitcoin multiplier! It is easy to use: any user can build a mine, then the user will receive bitcoins from all futher investments untill that mine is closed. User is able to upgrade his mine for a half of the current price thereby extend it's working time. (You'll be paid a return of 120%, 135% or 150% of your investment, which mine user choose depends on the percentage rule).
How it works?
You can buy one of three types of mines (bronze, gold or diamond mines), spending a certain amount of Bitcoins on it. Bronze mine costs less than the others (at least 0.01 BTC) and returns the user 120% of the cost of the mine. Gold mine costs more than Bronze one, and returns the user 135% of the cost of the mine. Diamond mine costs more than all others, but returns the user 150% of it’s cost. If you have a working mine, you receive bitcoins from all purchases and all upgrades from all users until the mine is closed (The mine has returned the promised percent). While your mine works, you can upgrade it, thereby extending it’s validity, and, accordingly, the amount of Bircoins it brings you.
Every purchase or upgrade of any mine affects the total price of other mines . That is the more often users buy Diamond and Gold mines or upgrade them, the more they cost. Purchases and upgrades of Bronze mines reduce the price of Golden and Diamond mines.
Buying mines
When any user builds a mine, bitcoins which were spent on building are distributed between all other owners of working mines in equivalent: The bigger parameter Return of the mine, the bigger percent of every investment it gets.
Formula:
Profit = Invesment * Return / TotalReturn
Where:
Profit – Amount of Bitcoins you received.
Investment – Amount of Bitcoins spent by user on building.
Return - Amount of Bitcoins, which your mine total brings.
TotalReturn - Total Return of the project’s all working mines.
Every working mine participates in distribution, so the more mines you have and the more is their total parameter Return, the more Bitcoins you obtain from every investment. When the mine returns the user promised profit, it closes and do not participate in distribution.
Upgrade of mines.
The user can upgrade any of his working mines. Upgrade increases mine’s parameter Return in the same equivalent as buying. That user has to press the ‘upgrade‘ button which is located under the mine he needs to upgrade. Upgrade works the same as buying the mine, except that the minimum amount of bitcoins needed for upgrade is twice smaller than the price of the building of the mine of the same type. For example if the minimum price to build a diamond mine equals 0.2 BTC, the minimum price to upgrade it equals 0.1 BTC. Bitcoins spent on the mine’s upgrade are distributed between all owners of working mines by the same formula as at the time of buying.
