very good guide. thanks for that.
i want to ask you something. i think about creating address... what if your created wallet has my private key also? i mean is there any chance to create same private key and address?
i want to explain more because my english;
for example; i use 1sT2GVdd3... for a while. and i have 10BTC atm. somebody, who wnats to start BTC create bttc address. and what a lovely... multibit create same address!!! :S is it possible?

The risk of Bitcoin address collision is approximately 1/2^160 address generated. It is more fesible to solomine using a celeron than trying your luck at making an address collsion. You can probably find an address collision if you build billions of ASICs specialised for such operation together with the computing power of the entire world and two suns. However, weak/flawed RNG can cause the address to be predictable. See this, this and this.

Yes that is why that new BIP-XXX or wtf was its name, is used to create deterministic addresses.

So you only need 1 random number as a seed and you can generate a really big hash from that using even a flawed RNG because without the initial seed they cant even find out the flawed mechanism

Random + Nonrandom = Random
Nonrandom+Nonrandom = Nonrandom

Atleast thats how i understand cryptography.

its great to know that people here are muvh concerned about newbies. the beginners are targeted more than the qualified ones. these steps are good to be followed and can help newbies in securing their wallets. yet another simple way is to download a wallet on your mobile device which gives high security as well.

Download wallet to your mobile device?

The mobile phone is the least secure electronic equipment that is out there. All mobile phone data is directly sent to a 3 letter agency.... Roll Eyes

can you elaborate further how mobile phone is the least secure device and details about that 3 letter agency ?
if it is that least secured we all would like to know about it !!
thanks .

I think an expert user doesnt need an antivirus anymore, because its more risky to use an antivirus than not, if you are an expert.

Who knows what spyware the antivirus would have in it, that could spy, or even send back information to a 3rd party.

This is why we stick with well known anti-virus software, and download from trusted sources at home.

Not downloading in public where someone might be "malicious" with your internet. Cold storage computer (again great job for raspberry pi) is meant to stay on a secure network such as a normal home network.

nice tutorial, thanks for the effort.

do you need both malware cleaner and an antivirus at the same time? i mean is it really necessary, i am using Eset smart security and it has Antispyware. do i need more?

about your software for monitoring balance, is it open source. because i would love to take a look at the code since i am a fan of programming.

yes

I would agree it's like 2 lines of defense. Should your antivirus catch it... yes. But this is not the perfect world. Having malwarebytes backing your AV is a good second line.

Also encryption or 2FA at this point is really a smart thing to do.

I'm securing my bitcoins rather well, on a separate dedicated machine

move bitcoins into separate wallets and store those offline.
To keep all your eggs in one basket is inviting disaster.

Offline is best. Cold storage can be great. Here is a few steps instead of pageful.

Buy Raspberry Pi. Only use it for BTC wallet related use, update to current OS and patches/fixes, install a linux anti virus. (Do not use this for surfing web, anything besides BTC wallet, not forums etc, etc.

Create wallet and store an encrypted backup on new usb drive, even two is not bad. And print off a paper wallet of it (Use the oldest printer you have that works with it, one with no network connection is best if want to be totally paranoid. After unplug Raspberry Pi. Store Raspberry pi, usb drives, and paper walllet or wallet's in safe places.

So two paragraphs and you can have a very secure cold storage wallet.

Im sure one of them saw it. But if you want to bring it to their attention go to meta.

But again chances are very very low of this being a sticky.

Why? Should I rewrite it, make it more readable? Perhaps easier to explain.

Please explain.

Sure this is my opinion. I could be wrong.

But I would first make it more readable. Pulling it up just a lot of bullets and numbers. Also a sticky is not meant for personal gain, so I would get rid of e-book and software you wrote. (again my opinion) Stick with well known tested software. Also no one is able to guarantee 100 percent secure. That is misleading. Lets say they had virus before installing your suggestions on virus protection, etc.

Add some more pictures, it would be even better to have entire process documented. You could even do a video if is to much for thread. Remove those horrible blocks meant to draw attention.

This would make it a better thread (in my opinion). Even if you do all this I still think getting a sticky is low. They are valuable space things such as rules, newbie information, etc. But that is for moderators above my pay grade to decide, Meta is place to bring it to them.
