Like Binance international for example.
If you know a bitcoin address sent we'll say 200 dollars in btc to a bitcoin exchange address. can you see what happens to it after? Like if it gets exchanged to other coins or even just sent to another wallet?
I know the exchanges can, but can individuals like you or I?
No. It is not possible to track the actual usage of an individual's amount.
As whatever amount you send to a particular BTC address always displays the total amount having with it on the blockchain, according to BTC whitepaper fundamentals.
And this total amount includes many transactions with small amounts.
So as an Individual user, never keep track of such fat and cold wallets of Exchangers for a specific amount.
