Re: Bitcoin Core Sending to same address multiple entry

sorry, I just realised that you cannot send using same address.

Yeah there's a client-side check that prevents this.

not always the case and can be done, check this tx address 1FMmEBoj7

I took this from another thread, he encountered a problem the exchange receiver only recognize one of them
eventhough possible why you want wasting txfee/bytes and possible problem (as stated above)

We're talking about Bitcoin Core here. The client side check means that the GUI of Bitcoin Core does not allow users to send multiple outputs to a certain address. It is totally possible for anyone to send thousands of outputs to the same address in the same transaction but it doesn't make sense.

You can do this by creating a raw transaction.
