It's a pleasure to have a new member in our midst on the bitcointalk forum, but just as "Satoprincess" have said, I will still make emphasis that O.P read the 3 thread she just provided, as they are all useful, while secondly, endeavor to use his first few months to study and understand how the forum works, because I may not know whatever reason your brother might have told you about this forum, but if it's money, then I will say that's a wrong motive, but was all about acquiring knowledge in Bitcoin/cryptocurrencies, then I will say that's a good motive, since this forum has got an encyclopedia of all the information you need to know about Bitcoin/crypto, & a 24hrs active Bitcoin enthusiast ever always ready to offer a solution to whatever challenge you might encounter.
