HelloGold cheats customers by adjusting fees and gold prices.
1) Before March 17th: the cost of buying gold was 0.79%, and the cost of selling gold was 2%. Trick # 1: Low fees attract gold purchases, but you won't know the cost of selling gold unless you want to sell back the gold you bought previously. 2) March 17: The cost of selling gold was increased to 6%, and the cost of buying gold was still 0.79%.

Why does the shortage of gold cause the cost of selling gold to increase? Trick # 2: They can arbitrarily increase the cost to invade our capital. 3) March 19: Due to customer complaints, the cost of selling gold was adjusted back to 2%, and the cost of buying gold was increased to 6.79%. This seems reasonable, but comparing the market gold price with the price of HelloGold App on that day, the market gold price increased by 0.2%, whil
