That i did not know this until last year middle of the year. I have been working as a bpo company back 2010 but didnt heard about this til i resign. For the past year after my resignation i was looking for a home base work or job online but still i didnt bump this cryptocurrency thingy. Til last year my sister introduce this to me but i did not listen that much lol! When i earn my first bitcoin i did not save it to at least to double my profit but i did not hold on it. So i promise my self to save my bitcoin and spend it at the very right time.
