Cryptocurrency is traded through a system called blockchain, which involves a ‘sender’ and ‘receiver’ of the transaction record, along with a ‘miner’ who verifies the transaction’s integrity. Essentially, it is a multi-party system that depends on computer hardware known as a server. Running a computer to calculate and validate transactions consumes electricity, and to participate in the blockchain network, the cryptocurrency issuer must pay a fee. This fee effectively reflects electricity costs. Since the blockchain system relies on electricity, the core of cryptocurrency ultimately comes down to energy. - Joseph’s “just my thoughts”
Umbilicaria esculenta is a kind of mushroom. To pick this mushroom up, a picker must climb a high mountain and approach a dangerous cliff because this mushroom is growing up between rocks. Therefore, umbilicaria esculenta is more expensive than other kinds. One day, the TV show "Korean's Dinner Table" on KBS 1TV showed an episode about the mushroom picker and his old mother. "Don't sell this mushroom at a high price." said the mother, because this would be sold at a higher price, many pickers would die from over-picking even dangerous situations. We should deeply consider what is the mission of our businesses. - Joseph’s “just my thoughts”
