that is not unusual when the price is volatile again and specially when it goes below a support line making it a very favorable price for investors to start buying it up.
the value (22 million bitcoin) doesn't seem correct though. i think you might be looking at the value in USD not BTC. and that is not the recent record either. blockchain.info shows peak at $4 billion last month:
https://www.blockchain.com/charts/estimated-transaction-volume-usd?timespan=180daysCMC shows 1,806,376 BTC
i don't know about other links but coinmarketcap.com doesn't show how much bitcoin was transferred! it shows daily trading volume.
