I came across a topic asking if people can really change their name to Bitcoin for 200btc
hereand my answer was yes speaking for myself.
That very topic reminded me of an issue my brother had as he was scammed of $2000 worth of BTC but we had to track the transaction using the transaction ID on Blockchain and when tracked, we finally found the coin in a wallet containing over $600m(36754.6) worth of Bitcoin after several transactional movement.
My questions~Are there private individuals who own and posses such amount of Bitcoin?
Owners maybe of crypto exchanges, or gambling sites.
~Why will one posses such amount as an Individual?
Not sure what you mean by this,

We don't have names associated to bitcoin addresses, except a few again, including exchanges. So there is no consequences, the only thing is that since it is in a public ledger, anyone can track the movement, dates when it was move, where it move, fees associated with it.
