Hello everyone!
I was introduced to this forum through one of my friends. I have heard that there are plenty of free opportunities for learning and earning by making appropriate use of this forum without any investment.
What should I remember as a newcomer and where should I begin?
As a beginner, you need to have target which should be mainly focused on, and learning should be your main target for the meantime because you need knowledge to explore in the forum and to earn as you have mentioned to be part of your goal of joining this forum.
That your friend can be in a signature campaign that earns him/her some money which I am sure is the reason you wanted to learn and joined this forum; it is not a bad idea to come with that aim but it will be more easier for you if you learn first so that you can have all the necessary knowledge that will help you rank up in this forum so as to achieve your primary goal.
Nevertheless, make sure you interact with all the comments in your thread because I have seen so many important links provided for you to use for your learning, these links and recommendations are good for you and will really help you in the future. Once again, welcome to Bitcointalk.
