That said, full nodes are not totally useless, but their only use is for *their owner* who is the only one who can *check for himself*.  But with that knowledge, he can do nothing else but acknowledge "that he has been had" or "that he hasn't been had", but that's about it.  The other advantage of a full node, for his owner, is that his owner can send out his own transactions, and nobody can know that HE was the one sending that transaction, as, being a full node, he would also send all transactions of light wallets connected to him.  So there is some kind of deniable anonymity of the IP address that sent out a transaction.

But that's about it.  These can be sufficiently good reasons to run a full node, BTW.
