I learned how to scalp crypto-currency and I do it well. I'd like to learn a new system. What do you suggest?
You should learn margin trading also. This is very helpful for a trader specially when the market is bearish. By this trading strategy, you'll be able to take profit when the market is not bullish. This is not complicated to learn, you may learn it easily either through watching a youtube tutorial or reading an article. For more questions, there are reddits, bitcointalk, etc. to help you out.
No, I disagree with your point of view. Because there are many professional traders who have been bankrupt because of margin trading. For new people, they should not learn margin trading, because their experience is not good enough to make a profit there.
They should continue to practice and experience.
