Any "donation" to the Genesis block can be spent but of course you need the private key that matches the corresponding known public key. Only the 50BTC of the coinbase reward of the Genesis block are unspendable which is a special case for this particular block.

But it's highly unlikely that any UTXO of the Genesis block will ever be spent. So, those UTXOs bloat the UTXO set and are practically taken out of circulation, which is kind of a shame in my opinion but who cares of that anyway.

Speaking of it, there's another larger "donation" coming in today...

Past March 14^th, 2025 large recent transfers to 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa (more or equal to 500,000 sats):

Current balance at time of this post according to combo(PubKey of Genesis block's coinbase) descriptor, including the unspendable 50BTC of coinbase tx: 104.38797936BTC (the difference to previous post's value and newcomer transaction are a lot of smaller dust wastes or whatever their purpose is).

This may differ slightly from what mempool.space or bitcoindata.science displays because the combo() descriptor "sees" all address types (except Taproot, IIRC).
