BTC and ETH price declines a lack of buyers with few sellers?

For BTC and ETH pay attention to price and volume

The BTC price has been falling for 30 days (with BTC avg daily vol on Coinbase =15,600 and an avg price of $10,500 ) . Prior to that the price was rising for the preceding 30 days (with BTC avg DV on Coinbase = 27,312 and avg price of $11,000). Same observation for ETH. Implication is that the recent weakness in prices is more of buyers on the sidelines while a small group of sellers have to raise fiat (maybe those facing margin calls on both equities and crypto needing liquidity to meet the MC).
