It is unclear who was the lucky recipient of the 7k Tez fees block. However, it is likely that the lucky person was someone who was actively participating in the Tez network and was rewarded for their efforts. Tez is a decentralized network that allows users to securely transfer and store digital assets. The Tez network incentivizes users with rewards for their participation in the network, which could explain why someone was rewarded with the 7k Tez fees block. It is possible that Tezloom was the lucky recipient, but this is impossible to confirm.
