Bitcointalk is one of the best forum that you can learn something or many things especially on what you are finding just like trading,mining and investing or even gambling.
You can go on trading discussions in order to post some questions about traders and if someones have a good answer on your thread then maybe it would be good if you will have a direct message to him/her using the bitcointalk forum.
Right. I also prefer to have a personal discussion. it is more detailed and can direct each other's opinions and experiences with direction. Regarding this trading, beware of trading signals that we do not know who made it, the market is very extreme changes so it is better to use analysis and strategies that we can.
