The positivity of bitcoin is you can earn money in many ways invest, trade, buy and sell. Of your a hardworking person anx willing to earn more you will use your time and money in a good perfect time especially if you a have a job and aside from thay you have a bitcoin account where you can you can connect anytime and anywhere. Bitcoin is a big help for others because som of the traders are money in need. And bitcoin helped them to support their needs.
The one negativity that I can say is not the bitcoin or any medium how to earn. It's the person itself. Why? Some people when they start earning money theier attitude and habbits affected by the money they earned. People change not because of other thing people change her/his choice, many people change when they have money. That's the negativity that I can say.
