Maybe this could actually be someone who has long lost access to the wallet but just recently recovered it and decided to move the funds to a safer destination. It might just be an upgrade in wallet security since all funds are moved into a single address that does not belong to an exchange.
I don't think it's a lost wallet that was recovered because the address has been constantly receiving a monthly reward of 0.0000547BTC. If it were other tokens I would have probably thought that the owner staked it in a kind of staking program that generates reward and when the time has elapsed, he/she decided to withdraw it to a different address.
who knows maybe it's also part of the early users who adopted bitcoin and hodl, the truth is that we cannot know everyone's stand and holdings on bitcoin, we have many whales who have been holding over a long time.
Well... These are just speculations but the first deposit of 1,432.92 was made to this address on 8th April 2013. So I don't think it's an early adopter except if it was sent by an early adopter from another address to this one and the owner decided to move it to again today to another address.
