Volume is not very meaningful. It just shows how much trading is happening on a given day. Each buying is also a selling on the other side. It can be many traders trading small amounts, or few traders trading big amounts. Volume is misleading. It only shows buying climaxes andf selling climaxes.

More important is how much of the buying is actually HODLing and not short term trading (removing the liquidity for a long period of time).
Also how much free BTC is floating on the market. If the number of floating coins is low (eg. no miners selling today, providing no extra liquidity) the amount of $ needed to pump the market is much lower. These values are constantly changing.
This is very complex because there are hundreds of exchanges. You just can't look at each factor in isolation. Need to understand the big picture.
The thing with bitcoin is that the fixed supply is finite. There will be a point in time when there are only a few thousand BTC left on excahnges for daily selling. But the amount of buying interest is constantly increasing...
That's why BTC is a self-fulfilling prophecy. It's math, mixed with fear an greed.
Valuations over $10 Million per coin are basically guaranteed over time. People who understand this math have already gone all in on BTC.

Many maximalists have already vowed to never sell (parts of) their stack, removing the coins forever. Lost keys remove the coins forever. People dying before they can pass on their keys removes the coins forever... Supply get smaller, interest gets bigger or stays the same... The perpetuum mobile of finace. Pure financial energy.
