By Jung Da-min Park Min-soo, 25, a college student in Seoul, has recently bought Dogecoin, a meme-based cryptocurrency. Whether it is a small or large amount of money, many of her friends, including herself, are investing in various kinds of cryptocurrencies. But as the cryptocurrency market is unpredictable, they often buy one randomly, rather than based on specific, detailed analyses. "Buying cryptocurrency has become a trend among our generation. We make a joke about randomly buying a type of cryptocurrency. We say, 'If you drink milk, then you should buy Milk Coin. If you made an online comment in reply to something, then you should buy Ripple Coin," Park said, referring to the names of two different kinds of cryptocurrency.
