This is no longer active so I guess it’s better that we select something that does not go out so quickly, hence I would suggest demo contest as it is something which is always available and the best way to start is with OctaFX company, it has excellent Champion and cTrader demo contest which has large prizes up to 1000 to 400 USD, so that is wonderful as it keeps throughout the year so I can start any time I wish or like.
