I do not mind donating 20% of the mining to you, as long as you state clearly in the program that such donation exists. Not like the other existing miners which state donations when the program is launched, your software does not show such message, making us believe your software is free of tax. I think this is not right or honest. I find your software is easy to use, and I suggest you add the information in the program (not only in the readme file) to clarify donations.
