Thank you for the quick reply. I asked this question because we were debating what would be the minimum amount of UTXOs that can ever be. So I guess 102 utxos?

@zndtoshi It's actually zero, since the coinbase transaction can send the block reward to an OP_RETURN output, which doesn't create a new UTXO.
