When we say Freelancing, in my understanding you can do any sideline that you can earn depending on your ability and understanding of something you are going to enter such as cryptocurrency. We can generate income in different categories such as the so-called Bounties which are divided into different categories such as Translation campaign, Facebook campaign, Twitter campaign, signature campaign, Youtube campaign, Talegram campaign, Reddit campaign, and article campaign are only a few are carried out by freelancers and the last one is crypto trading.
