The Cryptectum uses blockchain technology to refine a highly proven investment strategy in Switzerland - the investment in real estate. Rental of real estate in Switzerland has been an extremely lucrative investment with up to 8% return per annum for a very long time without interruption. Unfortunately, the minimum investment amounts required to buy a property are very high, as, for example, 3-room apartments in a city already cost over one million Swiss francs. This is where the Cryptectum comes in and, with the help of blockchain technology, allows small investors to profit from the rental of real estate.
