I've been monitoring it for the last few weeks and its daily volume can reach $5 billion to $8 billion in a day. But what makes me confused is that bitcoin prices tend to be stable during that time. And it seems that there is only a pump and dump in the 1K usd difference for a day.
I do not think there is too much of a reason to be confused about this, bitcoin is now a very big asset which can manage that kind of volume, in fact the higher the volume of the asset the harder it is to move, just take a look at shitcoins, their volume is very low and their volatility is quite high so it is natural that we are seeing the opposite effect on bitcoin, also its volume is that high because there are a lot of traders using leverage and this artificially increases the volume that we see in bitcoin every day.
