I did first hear about bitcoin through my sister. Before l ignore her saying that bitcoin can give me more salary than my work, but l told her that l have no time yet to used Celpone.Until then she always convince me to join because it is good. I didn't pursue myself to join into l saw my sisters life is quickly becoming rich.So just that time l decided to register also to have that opportunity also.Now my life is better than the past. Thanks to my sister for introducing bitcoin.
