You can't change it to what it currently is?

Yes - I do this *all* the time (as I don't normally run bitcoin so my client is *never* in sync when I start it). You have to wait until the GUI *appears* (so you can't do a tx *instantly*) but you certainly *do not* need to wait to be in sync.

Yes - a lot of the first year of blocks mined are coinbase rewards that have never been spent (which many assume are *owned* by Satoshi).

You can send me a PM if you like (am a little busy for IM).

If you are wanting to convert a raw tx from hex to JSON then use the "decoderawtransaction" RPC command.

I think a "green address" could be what you are looking for: https://en.bitcoin.it/wiki/Green_address (which AFAICT is limited to usage on Gox).

Looking very nice - hope to see it appearing in the next major release (although you can do this and more with raw tx's it is going to be helpful to have something so easy to use in the GUI itself).

One or more public keys are made public at the point of "spending" funds - this is still no real risk as the private key is never seen (except by yourself) although if any weakness is found with ECDSA (or some future quantum computer is built to discover private keys from public ones) then potentially any remaining funds at that address could be at risk.

It is for this reason that you are advised never to re-use an address.

Even if most "general" tx's were to be handled offline like this am sure SD and its like will be keeping the miners busy.

I am not sure how you can *prove* you have never seen the private key but if you assume some sort of tamper proof covering can be trusted then the other part (being sure it will work) could be handled as a signed message for the public key which can be made visible to all.

Yes - and this can be done with bitcoin-qt as well. Assuming you don't have a copy of the wallet on another computer then there is no problem doing this as tx you make are stored in your wallet (so it won't try and spend the UTXOs again).

Good one (don't know how I missed that).

You can move it yourself - check the bottom left of your screen (when editing I think).

And don't worry - I did not know that myself until after having made hundreds of posts.

I regularly send tx's when out of sync (with all versions of the client I have used) - where did this idea that you need to be in sync to send a tx come from?

If you are not worried that someone might *observe* your password if it appears on the screen then you could use Help->Debug then go to the Console and issue the RPC command: walletpassphrase <your passphrase here> 1

If you don't want it to be visible then perhaps try by sending funds to yourself?

Borland *compiler* on unix?

Are you perhaps referring to the C++ BuilderX environment (which is *not* a compiler)?

I do agree that we haven't seen such a threat - but it always is a nagging concern (damn it Satoshi are you sure you got it right?).

If you believe in the future of digital currencies then the only *exchanging* you will need to be doing is that of your efforts (to *earn* coins) or that for service/product providers (to *spend* coins).

The speculation part is really not that important (although a good way to try and get coins without much effort if you are prepared to take the risks that go along with combining non-reversible digital currencies with reversible fiat ones).

If you can earn coins and spend them for everything you need then why do you still need to be converting coins to fiat on an exchange?

It's back up now.

I don't have a list but do recall at least two different ToR services that disappeared along with peoples coins (they might have actually been *mixing* services rather than exchanges actually).

But whether they were just mixing services or not just think about it - you are taking a very big risk leaving bitcoins on any exchange as it is (several have been hacked or have closed leaving people in the lurch) so putting your bitcoins into an anonymous service that could disappear without a trace is just asking to be robbed IMO.
