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. Via crowdfunding Cryptectum collects funds, acquires a property and rents them out. Blockchain technology in turn helps to distribute rental income to investors in the simplest and most cost-effective way. In addition, the Cryptectum maintains the acquired property, which is a big plus for the investor, since he does not have to worry about it. However, an investor would also like to have a say in what property the Cryptectum acquires or whether the capital of the Cryptectum should be increased. The Cryptectum has integrated so-called proposals into the Smart Contract. The investor thus has the opportunity to vote on the acquisition of real estate or increase in liquidity.
