Actually this looks like some service hot wallet doing a lot of withdrawal transactions regularly.
We can only speculate. There is no way of knowing what this address represents unless there's a public statement about it somewhere.
The fee is definitively not spammy, 30 cents per transaction (equivalent 1 USD per 1 KB).
I concur.
Every transaction is the same fee. and looks like this is still not confirm they are all unconfirm except the 2 transaction below..
Wrong. Stop making useless posts. Only the most recent transactions are unconfirmed. This is because the fee included is sufficient or even above the recommended one.
And i think the owner is playing second trade binary or 1 minute trader..
Regardless of what they're doing, their paying adequate fees else we would see unconfirmed transactions.
