I use bitcoin mostly for the low fees associated with it, because if you use other payment systems like paypal the fees are very compared to bitcoin.
I agree! It is really nice to use bitcoins due to its low fees, and also using bitcoins to other transactions is more easier than other like paypal, netteler, Ok pay, Perfect money and so on. For me it is more convenient to use bitcoins and easy to follow the steps on wallet. No more hocus focus. In bitcoins, I can also buy load and pay bills and sell it immediately to those who need it especially in the middle of the night.
