Virtual currency lac

1. Lac, GBC and other so-called blockchain virtual currencies all operate in the same way. They are all Ponzi scheme + pyramid scheme
to put it simply: a dealer opens a market, and then draws people in to invest. Of course, the return is also great. For example, if you invest 1000 yuan, you will get 100-200 yuan in a week. What a banker with such a high profit can do to give you such a high profit is that he supports your profit with other people's investment, and goes on like this all the time, and pays the early entrants with the later entrants. The consequence of such a cycle is that bubbles are bigger and bigger. When no new people come in, the dealer will crash and run away. This is the reason why people who enter the site in the early stage can make compensation, while those who enter the site in the later stage will make compensation
in addition to making cash early, it also depends on luck. The sooner you find out to play, the better to buy a car in half a year, the better to buy a house and a car in one year, and the better to buy a house and a car in two years
however, it's not good luck. When no one joins in to fill the hole in front of us, if we don't quit, we should go to jump off the building and cut the chicken instead
there are risks in any investment. If you dare to do it, you may get rich overnight or lose money overnight.
