I think this is one of the most important events in the history of Bitcoin besides Halving.
I do not know how the user who gave the 10,000BTC must feel, but I do know that it will be a day that we will all remember, but no more than the one who brought the two pizzas and came away with the reward.
I have lost Bitcoins, but always when this day comes I do not feel so bad about myself, because I know that I did not lose or give away even a quarter of this amount.
May this day be forever within the crypto ecosystem.
