Donated 0.5 CKB to miners

Who has been sending coins to themselves every few minutes for quite some time now and has already donated 0.5 CKB to miners? :mechanical_arm:

Edit:
The fee is 0.00100000 per transaction, and the 0.5 is the total because the explorer only displays 50 pages. In reality, much more CKB has already been donated to the miners. Or what is the point of these transactions?

2,428,988.28947625 − 2,428,987.78947625 = 0.50000000.

This looks interesting. It’s just a regular secp256k1 address. There’s no type script in the cell, and no extra data was found in the witness. Everything looks like a typical transfer transaction.
