If the Tokens Transferred is high, and the Fund Flow Ratio is low, it might indicate OTC transactions are active. For example, when the Bitcoin price was ranging $10k in 2020, 4 million Bitcoin ($40B) moved on the network, where only 3% of the transactions took place on the exchange, and 97% of the transactions took place outside the exchanges. After that, many institutions announced that they had purchased Bitcoin, including Microstrategy, Ruffer, One River, etc.
