Do not use genesis mining to get BTC, It just takes too long and the profit is negligible. If you want bitcoin, I suggest you sell something and take BTC or an altcoin as payment or just outright buy it. If you have the time and patience you can use bitcoin faucets, though.

Before you do get bitcoin, you should ask yourself why you want it.

Do you want to make money? The only simple way is to get BTC, perferbly when it's low, and put it on a site like https://freebitco.in/?r=4683648 (that's my ref. Use it as a thanks if you think what comes next is useful:

It gives you extra satoshi everyday, up to 4% a year (yes that's my ref there, please use it as a thanks if this is useful). 4% is pretty good. If you have 1 BTC in it, you get a dollar out of it every couple of days. Not to mention transfering funds out for cheap on the site's withdrawal. JUST DON'T USE THE "MULTIPLY' tab. And be careful with your password.

A good way to see BTC is... it's money. Very versatile money. You can do everything you usually can, including paying with it on a BTC card. But you can do even more because of the low value of a single satoshi. Creativity is key.
