Thinking about how I started P2P lending in college, I seem to have seen an advertisement claiming that credit cards were used for free. I then tried using third-party payments to charge into P2P platforms during the interest free period of my credit card, and the plot was super exciting. Within a year, I opened seven or eight banks and more than ten credit cards, with a total credit limit of seven or eight hundred thousand RMB, and even set up POS machines to cycle through the interest free period. At that time, I thought I was a genius and could have paid interest for nothing. In the end, I ended up losing nearly 500000 yuan. If it weren't for the cryptocurrency industry saving me, my life would have been over. Now seeing the exchange extending its magic grip to universities, it seems like they are starting from a young age. College students lack self-control, and this could really ruin the lives of ordinary people.
