Re-Food is a movement fuelled through community goodwill, which aims to reduce hunger by fighting food waste. Created from the work of a single person, Re-Food has grown to become a non-governmental organisation [NGO], with the status of Private Institution of Social Solidarity [PISS]. Through networking collaboration, Re-Food proposes to bring an equilibrium between demand and supply of food products. The Re-Food strategy is based on the redistribution of food received through donations. All donated food is distributed immediately, and there are no stocks to be managed. In a system of food redistribution surplus, a sustainable collaborative network with significant economic, social, and environmental impact should be considered. The sustainable collaborative network is formed by volunteers’ work. The principal aim of this article is to investigate the Re-Food collaborative network. A qualitative methodology is followed, and the Chief Executive Officer (CEO) [R] and a coordinator of a Re-Food operations centre [C] were interviewed. Additionally, direct observations, and document analysis, support the investigation. The main result suggests a leadership model based on the acceptance of the different employees’ capabilities and motivations, and that technology can increase the effectiveness and efficiency of networking, as well as improve communication between people.

Cryptocurrencies have been gaining incredible popularity in recent years. Their number has grown from a single cryptocurrency to several thousand, and the peak was reached in the period between 2021 and 2022 when the number of cryptocurrencies doubled to over 12,000. Many cryptocurrencies exist only to make money for their creators. The emergence of cryptocurrencies has changed the way in which people store money, invest, and pay for products and services. The number of companies that support payments in cryptocurrency is increasing, although there is still resistance from some countries to this method of payment. The paper explains how cryptocurrencies can be used, stored, and what cloud storage methods are currently available. It also provides a brief description of technologies that are used to create cryptocurrencies. The second part provides an overview of the profitability of cryptocurrencies, explains whether it is actually profitable to invest in this form of “digital gold”, and presents the best options for mining cryptocurrencies.
