The use of blockchain technology provides transparency and security, while the potential for high returns on investment has attracted many investors. Additionally, these fundraising methods allow companies to bypass traditional legal obstacles.  It is worth noting that the legislation regulating the issue of tokens via ICOs has not yet been deeply worked out globally, so any individual or legal entity can issue new tokens. At the same time, there is no strict requirement for passing any audits or providing official reports, as in the case of an IPO (initial placement of a company shares), which makes this method of raising funds very attractive for IT companies. Besides, the threshold for participating inICO is usually minimal for investors. In addition, there are projects that provide absolute anonymity for investors, that is, not only other participants of the agreement, but also the tax authorities will not know about your investment in a startup’s tokens. At the same time, there were cases when a return on such investments, due to the rapid growth of a token price, amounted to hundreds and even thousands of percent per year (Ethereum, IOTA projects).
