There are different definitions of all-in. Let me give you a few examples.
If you have a family and you still have a mortgage to pay, your family income is 200,000 yuan a year, and you can barely make ends meet. In this case, the limit of all-in may be hundreds of thousands, and you generally can't hold it for a long time or don't cut it even if you lose.
If your family is good, your parents or older brothers and sisters have very high incomes, and you have good social resources, even if you have nothing at the time, when you find a good investment opportunity, you have a self-occupied house and a car, you may be able to all-in directly, and you can get back up after losing everything - this is the story of CZ.
Some people are shareholders of high-quality companies, with a steady cash flow and annual income in the hundreds of millions, so they can all-in billions or even tens of billions of high-quality projects, such as Duan Yongping.
