crowdfunding in Europe is not a scam. It is a crowdfunding platform developed based on blockchain technology. Every crowdfunding project on the European crowdfunding platform will issue a kind of digital currency, while digital currency exists in the form of an asset certificate corresponding to the corresponding entity assets, and digital currency can trade freely on the exchange. It provides a flexible push-out mechanism for users. Every coin has a different life cycle. At the end of the project, the tokens will be recycled and destroyed, and dividends will be paid regularly.
