i'm a newbie ! But my brother is a successful man who playing bitcoin ! He always make money by trading ! He recomended me to join a group of trade people who have traded before ! So a newbie can easily trade ! He also told me to have an app on your phone which updated every coin price so you can track everytime !
Trading could be on of the best way to make more money in bitcoin but you need to spend your money for trading on that trading site. It's good for you, you have brother that already success on trading. You can follow him and listen to his tips about trading. Mining also good to make more money actually, if you earn much money from trading, you can start learning about mining and invest your money by buy a mining tools.
It's a good idea, but for a newbie, maybe a signature campaign is a good start, especially if you want to start without funds. Minning, trading, investment, and more, need more money to make more money, so it might be better if you start without money.
