Some of the transactions are already got confirmations so they are not fake transactions, that's for sure.
What are "fake transactions" in this context?
I can't remember the details but i am pretty sure i read somewhere that you can make 2 transactions from the same address with the same bitcoins but only one of them gets confirmed, (both get listed on the blockchain, till one gets a confirmation) by adding more fee for one transaction than the other. Isn't there something like this?
But from what i see, every transaction gets a confirmation somehow, so there isn't any fakes. (the term i was talking about is probably; "doublespend")
