any advice for beginner trader ? what exchange to use and worth trust ? what coins to consider trading in ? what strategies to use ?
For beginners my advise is to equip yourself first with information about bitcoin what its origin, how does it works, what are the benefits, what are the do's and don'ts, as a trader the right time to buy is when the value is low. There are a lot of information on bitcointalk, experience in facebook and google.
