Just make sure that you read the rules of Bitcointalk in order to not get banned from the forum. I believe that this forum is a good place to learn about cryptocurrency and ask anything you want. The forum is divided into various tech and non-tech categories, so there's plenty to choose from. With that said, don't be afraid to throw your own hat in the ring with a new post from time to time. It's a great way to make your voice heard on subjects you feel strongly about, and some good exchanges often develop as a result. Also, don't be afraid to ask questions, as those most often make for the best threads. There are plenty of friendly people on the forum who are more than willing to lend a hand as you navigate your way through the world of cryptocurrency for the first time. Good luck, and happy posting!
