Only now do I understand that 150 yuan can buy a splendid barbecue meal with someone else's wife, 200 yuan can buy a nice piece of clothing to wear for a long time, 500 yuan can buy a ticket to a nearby city for a day of eating, drinking, and playing, 1800 yuan can pay for a three-day group tour across provinces, 5000 yuan can buy a pretty good phone that lasts for several years, and 10000 yuan can buy two fat pigs to fill the fridges of my grandparents, parents, and my own home, enough for three generations to eat for a few months, while I take this money and exchange it for Ethereum, hoping every day that it will make me rich.
