Rolling positions, simply put, is to try more and earn enough thanks to ,- -. For example, you earn 5,000 yuan in half a year as a food delivery. So you start with three hundred dollars, about two thousand dollars.

Ten dollars a hundred times every time, you read that right, it's ten dollars. Before opening, you should judge whether it is up or down, don't change back and forth, just identify one by one according to your own judgment, and if you lose fifty times, it means that you have misjudged, then go back and continue to deliver takeaways, and wait until the trend of ups and downs reverses.

If you lose 20 times, the trend is right, congratulations, as long as the rise and fall of more than 1% will become 20, take the profit of 10 yuan out and continue to open a hundred times, this is called rolling position, and then 1% will become 40 up and down 11% or so nearly 10,000 US dollars, do not invest any additional money, just roll the position. Bitcoin's 10% rise and fall - can come three or four times a month.

Give yourself - a goal, to 5,000 or - - 10,000 will no longer roll the position, simply take profits, if the greed can not be controlled, the lead will definitely get liquidated.
