There are no such services. Now. Point.

I didn't check - but even if they are not in existence "today" that doesn't mean that they won't be readily available "tomorrow".

That's correct!

you dont actually need to know someone running a mining pool as there are services out there for this.

Lets derail this thread even further...

Assuming the website does what "it says it does" it still cannot "undo a confirmed tx" (only a 0 confirmation tx).

So the basic advice of "don't use 0 confirmations" remains.

Yep, exectly my point

There are no such services. There is a site which declares that it is theoretically possible.
Do you see the difference?
OK, let me add one word. There are no such services working now.
Wanna to argue? Show me your results.

Guys - the "who is right and wrong" about this is really "not important" (apart from perhaps yourselves).

The sane advice is that you "don't accept 0 confirmations" for anything that you can't *also reverse* (such as web-hosting).

(the whole "I'm right and he's wrong" stuff is really just rather *boring*)

I'm pretty new to bitcoin but I have a question I'm unsure of. Can you spend bitcoin as soon as it is sent to you or do you have to wait for it to fully confirm? I've read different answers that you can and cant. Thanks.

I think that varies from "client to client" (the protocol won't stop it - but you'll end up with "stuck txs" due to the dependencies).

From memory the most recent versions of "bitcoin-core" won't use unconfirmed "inputs" (but don't quote me on that - as I am not 100% certain).

You are right.
With bitcoin core, you can choose to spend your own unconfirmed changes, but by default you can't use the unconfirmed outputs from someone else unless you create the raw transaction directly.
