It's a pretty dubious investment market for me. The market for expensive wines is quite complex and volatile. If you are not an expert in wines, it will be difficult for you to generate income using this investment market. In addition, as a result of the purchase, you receive a certificate. The scheme of further use of this certificate is not clear to me. Will such a certificate protect my investment? It's an open question. Also, it isn't clear how the value of a certificate can grow if it's "held for price appreciation"? If the price of any product is changeable and it can't only grow. This is contrary to the general rules of the market in investments.
