Fine wines are among the most profitable investment assets. Demand for investing in them is growing significantly. However, current fine wine trading platforms are complicated and have high processing fees. The CWEX exchange aims to establish easy to access and easy to use fine wine trading platform. Backed up by its partner, DotChain GmbH based in Switzerland, it guarantees anonymity and security of investment by providing blockchain based ownership certification to each bottle of wine traded on the trading platform. This system of trading with ownership certificates significantly lowers the current processing fees, leaving the buyer almost 80% higher value of his investment at the start.
