thanks but I already made my cold wallet  Smiley bitcoins on the way

You should use the "import watch only address" function on blockchain.info so you can keep easy track of the balance on your cold wallet and if any transactions occur.
haha, i just did that before i readed this
only the widget on my phone sucks a bit, can't make it smaller...

yes, that's what i mean, but is using a short password which ill never forget, Schoen468596 or something much safer than without a password or can any hacker just come up to something like this?

Don't use Schoen468596 anymore, but that is a relatively safe password, it is unlikely a 'hacker' could guess that as your password. You should include special characters such as: !#^$&@*()+- to generate stronger passwords.
Ok, and I didn't mean to use that as a password but just as an example
I made my first bitcoin paper wallet which I'll really use!!!!!  Cheesy
just printed out the private key without anything else at all so 99.9% of the people will not even know what it is when they see it
if someone wants to put a satoshi in my first paper wallet, feel free  Grin


Well now you just gave away the identity Tongue But it doesn't matter, bitcoin is still safe (it's just that people will see your balance now).

Funding is up to you!

You might get in a car accident and get amnesia...
I would advice you to use multiple methods, if one fail the other ones will most likely still be ok.
then i can still keep that password hidden somewhere where nobody will ever find it

You should chose a setup that gives you peace in mind and is not too complicated.
As long as the coins are offline, you will in 99% of the case be ok.

Bitcoin is about taking responsibility of your own funds, it gives you freedom but also responsibility.

so if i understand it well i take a little risk everytime i want to sell my bitcoins or move them to wherever?
so it would be better to make 10 wallets each with 1 btc? so i can keep the 9 btc in paper wallet and take 1 out if i need them?

The risk is that after importing your private key to blockchain.info, it will no longer be offline as I said.
So, your bitcoin will no longer be immune to hacking, phishing attacks, malware, etc.

I don't see any problem to that.


btw, what is a strong password for bip38 ?
how long does it have to be to be safe?
is it best to just make a sentence in the smallest language I speak?

It it better to be consisted of capital and small letters, numeric and special characters.
The longer the password, the more unlikely it will get cracked but at the same time the more likely you will forget the password.  
yes, but something like jé&"sdjqflj"é'(è'(!JJkjJKJKJI827F3!è§!FFddd5f('7d8f7d8f2d2dé"'(§28ddfdd22sdf(§§sd8s28Fgeit §(§ds56sè!!!!!çdsDdffdfdsFDsf65Dfdf66èè觧(§(5FdDF6dFD6DFfd6 i will not even try to get that in my mind, i can print it out but that doesnt make sence since i already printed out the private key, but I'm wondering if it makes sence to add a normal password like Pingo486955 ? what's the chance ill lose my bitcoins in case my private key gots stolen? 0.00001% or near 100% ? I've no idea...

I really advice you to keep your setup simply.
The bigest threat to loosing access to a private key is your self.

and it's 100% sure www.bitaddress.org gives me the right private key and they don't keep it thereselves? if exchanges could betray me, they could do that too? and i wouldnt even know that untill i bring them somewhere online in the blockchain in a few years

It is open source, and you can find and download the code directly on github. https://github.com/pointbiz/bitaddress.org
I haven't checked the code myself, but from what I heard, no one has found any backdoor anywhere in the code since the project started in 2011. https://bitcointalksearch.org/topic/ann-bitaddressorg-safe-javascript-bitcoin-addressprivate-key-43496

If running the page off line, then would there be no way Ninja could get the keys.
The only real concern anybody can have is the entropy of the random generator.

I use it, but only offline.
I have downloaded the page to an offline computer.

But I do not use the build in random generator for generating private keys (I am uncertain about how much entropy it has, other words, I do not trust it 100%).
So I throw a dice 100 times (To have a 100 digit base6 number) this will give me a truly random private key.

(I use a fair dice bought in Las Vegas actually)

In this way have my private keys never been "exposed" to the internet.

I have made a bunch 0.1 (with a offline bitaddress.org dump), when I need some coins to spend, then do I just scan the private key with mycilium - takes a few sec. and then is the coins ready to be spend.
Works pretty well.

For larger sums would I use the importprivkey command in bitcoin core.

Hi everyone,
Some time ago I bought 100 BTC (+70.000$), most of them I lose through hackers, mtgox, investing in HYIP, getting scammed by cloudbet... Now I have a bit less than 10 btc left (sadly worth nothing in compare to my initial investment). I'm used to keep them at exchanges like kraken and justcoin (which closed recently), then I discovered bitfinex and now I'm offering swaps there, hoping to maybe get back an extra bitcoin within a year. But I'm wondering how safe it is to keep my bitcoins there and offer swaps? I can make some profit there (and technically it should work as long as the owners don't run away or something went wrong on the website) but I'm also a bit affraid of losing everything. It also has some advantages, sometimes I really want to make some bets and recently I did it a lot bringing me from less than 3 to over 9 BTC. But that's mostly because of luck and maybe that could precent me losing my bitcoins that way because I never have access to my bitcoins immediately unless I change the autorenew settings in the website and wait for a few weeks. So what would be the best way to store my bitcoins? Going for the profit and let the bitcoins earn intrest on bitfinex or what do you think? My mail is safe now through 2FA if that would matter. If I deposit around 10 btc there I could earn around 2 mBTC every day by just offering swaps.


Why you dont try gambling? I dont invest, at start i got free btc from gambling sites, and i have won more that 5 bitcoins in less that 1/2 year with zero invest.

I keep my bitcoins safe on paper wallets, and i use a small bank roll for gambling. that is how it works fine for me.
nope, lost enough on scam bet sites like cloudbet, never make any bet again
