I was pretty skeptical about this one, but decided to give it a shot anyway. What do I got to lose? Coupla bucks? And guess what, it turned out to be a decent calc. New coins/algos pop up only few hours after listing. Though the calc may be a bit off profitwise and whattomine works better for me for some coins like BIS, but anyway I'm definitely sticking with it. And I got to give it's developer credit - man, this dude is patient! Like most of us, I don't have neither time nor patience go thru help or faq sections. I threw a ton of questions at him, accusing of taking money for such crappy service. If I were him, I woulda told myself to go f..k myself like a dozen times ))) He took his time to explain everything and voila... he's got himself a happy customer ))
