According to the Herald Economy, the cryptocurrency assets of Kim Hong-soo, a city councilor in Gangneung, Gangwon Province, South Korea, have skyrocketed by more than 1,000 times in seven years. The local councilor bought 195,555 OES tokens and 240,000 Donocle tokens at a unit price of 23 won (about 0.016 US dollars) in 2018, with a total investment of 10 million won (about 6,800 US dollars). These digital assets, which are currently valued at 12.90 billion won (about 8.80 million US dollars), can be traded on the decentralized exchange Uniswap, but the report points out that their liquidity is extremely low and there are difficulties in actual realization. Councilor Kim still holds these tokens purchased seven years ago, but the lack of market depth may affect the final realization of their gains.
