Earning through Internet is the smart way and best way. One can do his/her work from home.
But some cheaters are active in internet. They khow people are interested in online earning. So they put some attractive schemes and says to invest money in their site. After investing they do not give proper answer and payment. Some sites demand our bank history and aadhar card. They misuse it and finally we will in trouble. Some sites offer bitcoin and they do not pay. These kind of sites make waste our time and put in trouble.
I have bad experience with bitcoin provided site. So work with some genuine site like youtube, mouthshut etc.
