I have experienced a cycle of bull and bear markets, being an old investor for 4 years and 5 months, I have seen too many speculators rise to glory and then fall, from hope to despair. Contract leverage is a tool tailored for speculators, and it is also the place where institutions harvest the most investors. I was once a part of it. As time goes by, I continuously learn and understand the true big players who can make money in this market, the practices of institutions, and I deeply realize one thing: only long-term investment can change one's wealth in life, just like Buffett, the 4-year investment method!!!
