Coindash announced that 20,000 ETH had been returned to the wallet of the company with an address associated with a hacker who last year stole about 37,000 ETH during the ICO. This is the second time that the hacker returned funds to Coindash. On February 23, Coindash stated through the blog that 20,000 ETH were transferred to the company's wallet at 12:01:41 GMT. In July last year, the hacker changed the address for funds transfer, displayed on the Coindash website, and then stole about 37,000 ETH sent by ICO participants.

In less than two months in 2018, ICO projects received $ 2 billion in funding, while for the entire 2017, the total amount invested in the initial placements of tokens was $ 5.7 billion. However, as the structure of these sales is now more and more focused on large investors, ordinary users had to try to take part in buying tokens and get benefits from it. The data show that 84% of all ICO fees this year were received from large investors and during preliminary sales of tokens. When the method of collective financing only appeared in the cryptocurrency industry, it was a democratic way of raising funds, helping to unite the emerging crypto-exchange community. However, in 2018 the situation seems to have changed.

At the Cyber Days conference held on Sunday, co-founder of the Tezos blockchain project, which raised a record $ 232 million, Kathleen Breitman said the project is preparing to release tokens: "We plan on releasing the token and going rogue in the next few weeks. We're able to release the token on our own terms. For awhile I felt like I was being 'gaslit,' but then I unburdened myself of the morality of it. Things needed to move forward. It's unfair, but we need to ship the code".
