I once demonstrated a trade procedure for a friend who was new in trading bitcoins. All i did to make the trade successful was to introduce him with localbitcoins traders in our region. And he said that was cool after successfully trading.
I believe op is talking about exchange, successfully trading involved a lot of factors. When we are talking about trading in bitcoin or other currency trading we are talking about:
1. Margin trading.
2.betting
3.Arbitrary trading
4. Conventional exchange
For you to be successful in trading you most developed your skills and knowledge about how each one of them work. For Margin trading, betting and arbitrary trading, you most leaned trading money management principle and other trading patterns.
