Every transaction you safe so much on fees. Be it a purchase or simple trade, I earn a lot on not paying these ridiculous fees the banks charges us.
The fees are the main reason to use bitcoin. If just people were aware of this, banks would have no reason to exist anymore, or they would adapt their fees right away.
Remember the moment you know how to use bitcoin and experience the control you have, you will never stop using bitcoin..
Low fees and low transaction costs are the main reasons why people are attracted towards bitcoins, as it is comparatively very low as compared to banks or western union where they charge heavily on their customers, it was monopoly for bank and exchanges but with the existence of bitcoins it has lowered down their customer base and people are turning toward bitcoins as the fees are too low.
