The valuation should be 3000+, and Maotai has risen faster than the Rockets in the past two years. I advise you to keep it for a few more years, just for profit. If the emergency fund sells for 2500, it's not bad, that's all. Long-term collection is very profitable, but the collection conditions are also very strict, such as the humidity of preservation, the location of storage and so on. If it is not well preserved, the wine will go bad and affect the price. As you said, if the seal is cracked, you should pay attention. Easy to volatilize and deteriorate. So personal advice can be sold.
