I personally am a bitcoin fan. Not just I can earn in here, I can also learn and gain knowledge in here. Because of my busy schedule in school, I seldom use bitcoin as much as I want to. I heard this from my love one. He heard it from his thesis mate and tried to use bitcoin and it's legit so he shared it to me but I read many posts in social media who are sharing their experiences in using a bitcoin and their feedbacks are positive.
