462  Economy / Exchanges / Bitfinex - local wire transfer possible? on: July 14, 2014, 01:46:26 AM
I'm based in HK and I have a HK account in USD.
If I do a deposit on Bitfinex, will it still be considered an international wire transfer with all the fees attached to it?

Thanks,

With this I would feel quite safe... There are evil wizards around tho... physically disconnect LAN cable when not in use for paranoia users.

Many malware apps are smart enough to go dormant when the network is off and will reactivate when it comes back.

For 40$, you could make a dedicated raspberry pi wallet entirely offline.
Download the official OS Image. Add the required packages. Then disconnect from the network forever. Install the rest from official tar balls. Create an encrypted wallet and you are good to go.

For backups, take a picture of the qr code from an old phone with no SIM card. Check that they can be decoded. Save to several micro SD. Hide them. Then wipe your phone. I hope that it's good enough.

How can a merchant even ISSUE two times a spending of the same bitcoins?
How can this happen in an "automated" way, because I suppose I can't double spend my bitcoins from my bitcoin wallet, right? So it must be something coded somewhere, right?
And if this is coded, how to trust the issuer of those bitcoins again?

Do you mean in general or in this particular case?
In general, if someone intentionally sends a double spend they shouldn't be trusted anymore. That's the reason for this warning.
In the case you mentioned, it is not a double spend. The miner found a solution to a block and was rewarded for it. But because someone else found out a solution to the same block and his chain ended up being longer, the former miner had his reward rescinded. This is why rewards take 100 blocks before being confirmed.

Someone decompiled the jar at https://bitbucket.org/indistic/rat/src

It's a trojan that turns your machine into a bot.
From what I see from the source code...

It connects to a remote server, logins with the credentials that are in its config.xml
Then it waits for orders.
There are several commands. You can see in the options folder.
- pop up some message window
- execute arbitrary system commands,
- execute code that it sends to you,
- upload a plugin, i.e. new code to enhance its functionality
- browse to a url
- upload a screenshot

Yeah ... it's pretty bad.

It's the later: There is a pool of 100 keys in your wallet. See https://en.bitcoin.it/wiki/Key_pool

Is this true, and if so, how was that possible?

On the second page, you can see a transaction that was not confirmed.
https://blockchain.info/tx/ced06cedbfbc0895cdaec6f7065d8c9248797acd1da47796a8885ddd1e0c4a96

If you follow the block, it shows it as orphaned
https://blockchain.info/block-index/448192

So that's it, it's an address that found a hash for a block that ended up being dropped. That coinbase transaction didn't get confirmed and
the address was flagged as suspicious. Nothing wrong though.
