IMO
The best way to start trading is with "FREE" or "demo' money. What better way to learn than by TRADING?
I would strongly suggest anyone who wants to learn, dabble or whatever start this way.
Head over to simplefx sign up and use demo account... Save your money until you've learned a thing a two.
Full review of SimpleFx HereThey have similiar method for trading but bitcoin trading provide higher risk compare forex
IMO , forex may easier to profit since they using stable value meanwhile bitcoin trading have unexpected value
