I dont know where u got ur numbers but 50-60 dgb is not 5-6 dollars its around half
Anyways there a a lot more stuff more  profitable then dgb atm ohh hell even zcash might be more profitable then dgb skein right now
Anways dgb used to give a lot until its diffculty exploded like a lot and price decreased to half +
Anyways U should use whattomine.com and compare ur dgb skein profits with other coins profits and mine the one more profitable and convery it into what ever coin u believe in .
And with Bitcoins Lightening Network DGB might die or fade away .
