Joules is a self sustainable smart contract
You'll need your own wallet address which you can get here.
You'll also need the Google Chrome plugin, ATHMask
Joules works by paying dividends out to it's stake holders.
When you Deposit Atheios to the contract you are issued joules(stake). Overtime you will be issued dividends, you can either claim or reinvest your earnings. If you claim your dividends the ATH will be sent to your address. But if you reinvest your dividends you will will recieve more joules(stake) which will yield to a higher dividends payout.
The fees allow for dividends payouts to be sustainable.
*Deposit fee: Amount/(100/7) = deposit fee - (14.28%)
*Withdrawal fee: Amount/(100/4) = withdrawal fee - (25%)
*Stake Calculation: stakeValue + ((100/7)/totalstake)
*TotalStake is calculated by: totalstake issued + Stake increment
Joules gives you the opportunity to grow your investment by reinvesting your dividends that recieve (which increases your overall stake)= higher dividend payouts or you could look at it as passive income where you'd just claim your dividends and do what you wish with them. The possiblities are endless.
