How exactly can you see how many tokens are on the exchanges? Most exchanges
use hundreds of wallets, which makes it nearly impossible to determine how
many funds are actually at the exchange. If you try to determine the amount
by looking at the order book, you should be aware of the fact that many shady
exchanges use spoofing to give the impression of support "walls".

I also have no idea why you think that it is possible to see what the big holders
are up to. How would you track their movements? I don´t think that this
is doable and cryptocurrency trading markets are just as opaque as
stock market trading.
