so in the poster above who lost all his money with bitcoin what did he do wrong that I should learn.
dropboxing/google drive his addresses? storing them on his pc? using an exchange site like bitx.co.za?
Firstly, Don't upload your wallet to dropbox... that's just asking for someone to steal your bitcoin.
You address can be viewed by anyone, they can't do anything with that. (Public Key) - the one you should be worried about is your private key (your wallet.dat file, essentially)
Check your PC for malware, and also, always encrypt your wallet.

and what should most average people do to secure their bitcoins?
encrypt my address, or copy my address off my pc and store it as a paper form for maximum security,
(IE: write down my bitcoin address on paper and store it like a R100 note?( does such a thing even exist?).
Check this video out!

[video=youtube;I1uefzJJ6nM]http://www.youtube.com/watch?v=I1uefzJJ6nM[/video]

it makes sense but I looked at my bitcoin.info and saw that everybody in the world can see how much I have in my wallet,
does that mean it can be taxed by SARS at some point in the future?
It's pretty easy to hide your bitcoin, you can generate as many address and wallets as you want and your name isn't tied to any of them like a bank.
You should report your capital gains though.

and does it mean that if you know my address and know how much I have in it you can steal it?
Unless they have access to your wallet.dat file, No.

what happens if somebody (however unlikely) types in by mistake your bitcoin address, does that person suddenly have all your money? is there any safeguards against that? or does using the barcode/QR reader make it easier.
QR Codes help, copy and paste works too. you should need to type them out manually, almost ever.
There is some "Checks" done to addresses though, if a letter or two is wrong it will just be invalid and tell you - but it can happen I guess if you REALLY type an address wrong (Though I'm not sure what the odds are of typing a different, yet valid, address)
There also is no problem of "o" and "O" and "0" or "i" and "I" and "l" and "L" - those type of characters are excluded from addresses.

Someone will not have access to your money by knowing the numbers in your address - this is not like credit cards, lol - they need your phyisical wallet.dat and encrypted password.

one other thing, I noticed the multibit client only shows US$ is there a ZAR setting or can I only see that on the bitx site linked to the ZAR/US$ rate at the moment, I noticed other currencies but no ZAR?
Unfortunately not, but it should come soon. i'm also waiting for it. :eek:

This only applies if you upload to a publicly shared Dropbox folder. Beyond this, if you're suggesting Dropbox is compromised as well as 256bit encryption then we have bigger problems than wholesale Bitcoin theft.

I have yet to find any vaguely satisfactory explanation for how mine and many others' BTC was stolen. Until I do, it would be idiotic to throw away any more money, and I urge anyone contemplating it to do a lot of research on the risks first.

I'm not suggesting the encryption has been compromised, I'm just giving tips to eg2505.

You probably had keylogging malware or a very weak password on your wallet. That doesn't mean the rest of us are vulnerable.
Your paypal could have been emptied the same way, that doesn't mean paypal itself is broken and nobody should ever put their money in paypal because your money was hacked.




Mining is super easy.


1. Install QT wallet software for whatever currency, and sync it.
2. Close it, and run it again with the "-server" command (You may do this by creating a shortcut to it and adding " -server" at the end)
3. Install CGMiner
4. Create a .BAT file in the cgminer directory with the following line "cgminer --scrypt -o localhost:3333 -u keeper -p mypassword"

--scrypt is for crypto that uses scrypt and not SHA256 to mine
3333 is the port number
keeper is my username
mypassword is my password

The port, name and password should match the data in the .conf file in your user directory
(C:\Users\*Username*\AppData\Roaming\ApeCoin.conf)

rpcuser=keeper
rpcpassword=mypassword
rpcport=3333
rpcallowip=127.0.0.1
daemon=1
server=1
gen=0
block_nTime=1317972665
block_nNonce=2084524493
addnode=24.186.150.212

Mining bitcoins is fairly pointless at the moment. Have a look at mining alt coins

What does the server command do and what would be in the config file :confused:

I just installed LiteCoin app, synced it up to the current week.
Pulled my receive address and added it to the pool.
Ran CGminer.

WIN!

Rather mine using a pool, its faster, and all the pool sites have easy to use instructions

Could you post your script?
What is your hash like?

Running a Toxic 270x and getting only 420k/hs. Thinking of replacing it for a 290x or CrossFire 280x

420 sounds about right for the 270x. I get 650 or so. Your script seems ok at that hashrate.

If i want to get closer to 700 like other guys are with this card i need to mod the bios and dont wanna do that

cgminer --scrypt -o stratum+tcp://xxxx:80 -u xxxx.1 -p xxxx -g 2 -w 256 -I 13 --lookup-gap 2 --thread-concurrency 8192 --gpu-engine 1030 --gpu-memclock 1500 --shaders 2048

Thanks. :)
Looks like I'm on the hunt for a 280x now :D

Careful kids. Bitcoin currently teetering on the edge of a cliff. If it closes below 800USD expect the floor to be removed.

Would actually not mind if it had a correction. Can invest a few bucks whilst it builds back up again.

Where is this graph from ? URL?
It is generated using the tick data feed from BTC-E which I have stuck through a Renko algorithm and applied a Ichimoku chart to visualise support and resistance....

In short, no URL, I am generating it.

And in other news, the floor is dissipating rapidly.

Porn.com accepted bitcoin, now Naughty America.
Overstock accepted bitcoin, now TigerDirect.

This is huge. The second person to jump in is always much bigger news than the first, soon nr.3, 4 and 5 will follow. :)
