I found that some friends only know about spot and contract, but don't know what rolling is. Here, Brother Jiu will tell you what rolling is:

To put it simply, rolling means trying more and losing more, and making enough in one go.

For example, you made 5,000 yuan by delivering food for half a year. Then you start with 300 US dollars, about 2,000 yuan.

Each time, you open a hundred times with 10 US dollars. You read it right, it is 10 US dollars. Before opening, you should judge whether it is rising or falling. Don't switch back and forth. Just identify one according to your own judgment. If you lose 50 times, it means that you made a wrong judgment. Then go back and continue to deliver food until the rise and fall trend reverses.

If you lose 20 times and the trend is right, congratulations, as long as the rise or fall is more than 1%, it will become 20. Take the profit of 10 yuan and continue to open a hundred times. This is called rolling. Another 1% will become 40. The rise or fall of about 11% is nearly 10,000 US dollars. Don't invest any extra money, just roll. Bitcoin's 10% rise or fall can happen three or four times a month.

Give yourself a goal, stop rolling over when you reach 5,000 or 10,000, and simply take profits. If you can't control your greed, you will definitely get liquidated in the end.

This wave is over, and you may have tens of thousands of dollars. Then wait until you think you are sure of a rising or falling trend (maybe it will take several months), and then take 500 dollars to start opening. You read that right, it's still 500 dollars, and you still open 10 dollars each time. If you are lucky enough to encounter a one-sided market, it is very likely to make millions in a few days, but it may not take one or two years for you to make a completely accurate judgment and just avoid the ups and downs.

If you can't help it, can't control your hands, have no patience, and don't have a strict execution plan, playing contracts will 100% get liquidated and go bankrupt.
