The blockchain pet project has seen a large area in the second half of the year. Recently, a platform called "Bit Pig" was investigated by the police. Mr. Dong from Changzhou, Jiangsu Province was pulled into an investment group. Every day, a teacher lectured and introduced the virtual pet “Bit Pig” using “blockchain” technology. It was claimed that the pig was acquired by the platform 15 days later and had a 28% return. After the small profit, Mr. Dong transferred 100,000 yuan to adopt it again. Until the platform could not be landed at the end of July, Mr. Dong knew that he was cheated.
