thats a lot more volume than i thought based on the comment i read yesterday. also just found this site https://data.bitcoinity.org/markets/price/6m/USD?c=e&t=l https://data.bitcoinity.org/markets/price/6m/USD?c=e&t=l which has historical price and volume data. looks like 24 hour volume has generally been around 100-150k BTC / day could still manipulate markets with 40% concentration and that much liquidity, but would be much harder than if the daily volume was on the order of tens of millions like i mistakenly thought
