But the mined transaction has different TXID, input and output amount than the one you've been broadcast(ing).
Chances is OP gave a different signed raw txn to "neutraLTC", it also contains a 1BTC output which looks like the bounty.
Yes, I have been wondering about that - perhaps they came and grabbed the first version of the TX and tried it and it worked (especially with the much higher than usual number of transactions in mempool at the moment).
The OP has been offline for two day - no doubt because they were exposed as
a mult-alt scammer, so I doubt anyone will get any kind of thanks.
