Is there any disadvantage to importing a known private key, or easily crackable private key, into a wallet with other personal addresses that aren't meant to be public.

For example, say I have a web wallet on blockchain with 3-4 personal addresses, and I import the private key that corresponds with the hash of "password". What are the implications here? I'm probably not clear on how change works, could it accidentally be sent to this address?

Does the answer change anything if you are using different wallet clients (web vs local)?

Looking to sell a CD key that allows download of Batman: Arkham Origins. Just got it with a new video card and don't want the game. Retail is ~$60, will sell at a significant discount. Prefer to accept BTC

Will go on ebay in ~24 hours if I don't get any responses!

Any exchanges offer or plan to offer option contract creation on bitcoin itself?

Would be interested to see what kind of premiums 2-4 year LEAP contracts would fetch

 

Noob question here but I made a paper wallet today and had a thought I couldn't quite work through in my head, or sort out with some searching.

When restoring a cold wallet (or importing keys into a new wallet) is it true that all one needs to do is enter in a private key to gain access to the balance? What would stop someone from just trying a private keys forever until one hits? Surely the probability goes down as more private keys are generated (thinking out 100+ years)

I was under the impression that the private key needed to MATCH the public key – which means you would essentially have no chance of guessing this on the first try – so brute forcing was essentially useless.

Since this is fairly straight forward I must be missing a key piece of how it works – someone care to explain as if I were 5? I thought I had  a pretty good handle on public-private key – guess not.


Also - what if two people are assigned the SAME private key..this is possible (although i understand overwhelmingly unlikely). This breaks the system? I cant believe that - again I thought the private key had to match something, and was only associated with one address.

Campaign runs out in a few hours. Need to get to 30 so we can all get our shirts!!

After a successful first campaign, and numerous requests to do a 50 Cent parody design, I've launched the second Friedcat Fan t-shirt!

Lets get this to 30 so it becomes funded!

All - our Friedcat crowdfunded tshirt is funded! Still accepting orders until tomorrow morning. Use it to explain to people how awesome Bitcoins are.

Came up with a decent idea to help spread the word about Bitcoin on a public, non-invasive level. I used the crowd funding apparel site Teespring to create a Bitcoin logo tee. The hope is that users can wear these shirts and strike up conversation on a casual basis.

Too bad they don't accept Bitcoin as a payment method.. let me know if you have any suggestions!

I'm looking to do some analysis on all of these mining securities bounding around, I'm fairly new and only have the info I've gleaned from these boards..so this will serve to educate me and others on exactly how the ASIC company is set up. Does anyone have the info necessary to calculate? I think getting a market cap will put into perspective how over or undervalued these shares really are.

How many shares exist?

How many shares issued?

What % does the public own?
