According to the 21st Century Economic News: Regulatory arbitrage caused a new chaos in ICO, according to the 21st Century Business Herald, due to different regulations on the blockchain and ICOs in the world, many more ICO projects have been registered in countries with relatively low level supervision such as Cambodia, Malaysia, Seychelles and Malta. Business insiders said this operation was actually the "regulatory arbitrage." Recently, China, the United States and some countries have had strict regulations on ICO, but those countries with low level regulations could not only obtain a relatively relaxed fund-raising environment (including fund-raising targets were not limited to the scope of investor compliance), but also could use local supporting policies to expand the blockchain application scenarios. Regulatory arbitrage caused a new round of ICO chaos, and some of the fraudulent ICO projects have come back.
