You have to think about is This worth?
First of all I try it with my computer, but using only one computer is not worth it in Europe because of the electricity cost for my computer I was only earning 0.03$ each day, but to be worth it I should earn at least 0.05$ to pay my electricity so its a losing system.
But to be really effective you have to build a farm why using cryptotab?
Because cryptotab is really great with the affiliate system to increase the amount you earn really quickly
And the other thing is to use Smartphone because you can use old phone and let them work for you with the app on google play or appstore they are many people that show results on the internet you can see here some example of the farm system. It's really easy to do and really effective because you don't need a good phone but a good connection.
