One of the developers of the standard tokens, Ethereum ERC-20, and DApp-browser Mist Vogelstein Fabian (Fabian Vogelsteller) provided he created the model of “reversible ICO” (RICO). It is based on a smart conract that allows investors to return their funds in exchange for their acquired tokens at any moment of the project. In this case the returned tokens can be purchased by other investors.
Vogelstein considers himself somewhat responsible for the boom and the ICO hopes that his concept will reduce for investors the risk of becoming victims of fraud, and will motivate the organizers of the ICO is responsible to fulfill its obligations.
Among the disadvantages of the model the author refers to less stability in the question of accumulation of funds, that, on the other hand, should encourage the organizers RICO to look for other sources of core funding: for example, private investors are not involved in tokencache.
Recall that the auditing company Ernst&Young (EY) recently published a report on the current status of the most important ICO projects last year. According to the conclusions of EY for a year the price of tokens 86% of the projects fell below their prices of time of entry in the listing, with 30% lost a substantial part of its values, and showed a positive trend 10 most successful ICO projects last year.
