Earlier quoted context omitted.
Daily trade volume doesn’t represent what it used to as market makers/HFT algorithms get into and out of positions several times a day. What matters for estimating impact is essentially the net flow across the day/week/whatever not the transaction volume. It’s unlikely to precipitate a sell off but a 1+% dip in the short term isn’t unrealistic.
Ethereum has 1% dips regularly, on the hourly. In crypto, that’s generally considered very stable.
I doubt anyone would try and liquidate it in a single transaction on public markets.
