Almost every time I check the exchange inventory of BTC, the direction of the inventory change and the price are usually inversely proportional. From the beginning of the year until now, the price of BTC has doubled, while the BTC inventory has decreased from 2.7 million to 2.26 million coins, showing an overall downward trend. As long as the trend remains unchanged, there is no need to worry too much about market fluctuations. It is worth mentioning that yesterday the exchange inventory increased by 20,000 coins, of which 18,000 coins were added by the South Korean exchange Bithumb. This exchange has a total of less than 30,000 BTC, most of which flowed in yesterday. Are Koreans the first to start selling?
