take my stats as a example . i have earned 67.35$ since i have joined clixsense and my current balance is 0.76$ . this "0.76$" i have is the result of all the cashout's ,purchases,fundings etc .but the wired thing i see in your stats is that you have the balance higher than your earned amount .if i am right this should'nt be the case.
there is no fees you need to pay at any point unless you'r requesting a cash out .
