first of all where is the proof of this "trace".
second of all no chain analysis has ever been reliable!
and finally the address posted doesn't have 8.1 million bitcoins it only has 2326. the 8.1 million is the total received which is basically blockchain.com summing each time it receives a payment in other words that is the total received of 150485 transactions.
That's bitfinex wallet, just to make things clear.
The rest is a bs topic, with bs data, pure clickbait trash.
Even the article mentioned is only talking about 700 BTC.
maybe even NSA CIA/MOSAD
You've forgot to mention the reptilians, Soros, NWO and satoshi.
