Thank you for watching. I am conducting alchemy experiments to extract gold from junk computers and game software purchased from Hard Off and Book Off, and make ingots. I also bid on gold and silver products and old coins and silver coins on Yahoo! Auctions and Mercari, appraise them for authenticity, and sell them to precious metal purchase stores to verify whether it is possible to make money from gold and silver. Rare metals such as gold are contained in the home appliances and smartphones that everyone has in their homes, and urban mines are close to us. This channel challenges everything related to gold, such as refining gold using tincture of iodine, the ancient cupellation method, melting and casting precious metals, and making bullion and gold bars.
