Honestly when i didnt know about bitcoin, i thought it is used for illegal activities such as illegal gambling, drugs, and many more. And also before i thought about bitcoin is a scam. But when my cousin tell me what bitcoin is, it is wasnt illegal. Then i started to create this account and learn more about bitcoin and other cryprocurrencies. Now im here and earning some so it will help my studies. It help alot actually if your intelligent enough. I agree to those people who still doesnt know about this cryptocurrencies. It is okay but you need some patient and conviction to tell them what is this.
