Actually, mining DOGE and exchanging it to BTC is more profitable than mining BTC, even if there are fees for the exchange... At least for me it is.
So basically you are saying that is easier to make money mining doge than any other coin. So why shouldn't we all starts begging because it is easier to make money this way rather than working?
Just because doge is more profitable to mine with your mining equipment it doesn't make it any better than btc
