Thoughts?
Brought to you by some dude that suggested people to buy at $800-$1200:

That doesn't mean that he might not have valuable info now. Lots of people have made bad calls regarding when or when not to buy.

Interview that was posted yesterday indicated they are going for a Q1 launch for Gemini. No ETA on the ETF was mentioned IIRC.

What no time frame? Too easy, yes it will hit $1,000 again. When is the better question.
1727  Economy / Speculation / Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion on: February 16, 2015, 10:15:47 PM

I didn't post it because of news I just found it interesting. Those two are more and more in media lately there should be some news about Gemini and ETF soon Wink

Looks like the article was written today. I haven't read this particular interview yet, thanks for posting.

I prefer the term mildly autistic. And so what?
1730  Bitcoin / Development & Technical Discussion / Re: What are the odds of creating the exact same first 8 character vanity? on: February 15, 2015, 04:55:07 PM
I know the odds of someone "cracking" your private key are astronomical, but you know that there are high end computers that all they are doing is coming up with private keys, you randomly guess tens of thousands per second, it wouldnt take long to find at least a few that would match..

Almost like playing a lottery right?
I've put a lot of thought into this and I created a script that was generating 20,000 keys per minute and stored the key pairs into a database.
The bigger issue I ran into was checking those addresses for a balance, that was much slower around 40 addresses per minute, since it was over the internet and had to check it against the blockchain.  The next HUGE issue was space. In just 14 hours I had over 15 GB of data storing ~20 million key pairs. The storage and checking these keys is a huge issue when trying to get lucky with a private key.

At this point I stopped and I did the math: if I had unlimited storage space and kept running the script for one year I would only generate 10 billion key pairs taking up 10TB of data, this is out of the 1,461,501,637,330,902,918,203,684,832,716,283,019,655,932,542,976 possible keys.

I have no idea what you are trying to explain. Is this supposed to be a game you are trying to make? What's the point of the 4 corners?
1732  Economy / Speculation / Re: What is your price ? on: February 14, 2015, 05:30:38 PM
If bitcoin's exchange rate goes to the moon then adoption will be so wide spread I won't need to exchange for fiat. So my price is when I can exchange my BTC for a nice house, and I'd still probably only use 50% max of my stash and hold the rest.

Walsoraj is the only person on my ignore list because of his constant ripple plugs. Post about your centralized corporate proprietary coin in the altcoin section. It doesn't belong here.
1735  Economy / Speculation / Re: Coinbase volume on: February 12, 2015, 01:54:34 PM
Wow, I expected coinbase's volume to stay below stamps for quite a while, guess not. Do you think it's from a large amount of users creating the volume, or a fewer amount of users but with deeper pocket books? Maybe some big players were waiting for a regulated exchange before putting in large $ amounts?
1736  Bitcoin / Development & Technical Discussion / Re: How to Create a Bitcoin Address from a Coin Flip on: February 09, 2015, 05:24:52 AM
Please please please do not do this. The cryptosystem which Bitcoin keys and addresses are part of assumes for its security that its private keys are uniformly random numbers. Flipping coins by hand will definitely not give uniformly random numbers, and is probably so biased (depending on your hand, the coin, what side you pick it up from, the surface it lands on, etc, etc) that you can measure it yourself by just flipping a coin and counting the zeroes and ones.

If you swap out one component of a cryptosystem for another you have constructed a new cryptosystem and need to argue its security. And I guarantee you won't find a good security argument for "Bitcoin script with biased randomness".

To add to the presumption of insecurity that should be applied to all new cryptosystems, let me point out that much of this one is gibberish:


Quote
Every Public Address corresponds to exactly one Private Key and vice-versa.
This is simply false.

Are you talking about possible collisions?


I believe he is referring to this:  https://bitcointalk.org/index.php?topic=24268.0

So there are 2^160 public keys but only 2^96 private keys? Ho does that add up?
Are there private keys than unlock more than one public key?
There are just under 2^256 private keys, just under 2^256 public keys, and 2^160 addresses. There are some addresses that have more than one corresponding public key and thus more than one corresponding private key.

1738  Bitcoin / Project Development / Re: Bitcoin card game on: February 08, 2015, 04:46:42 PM
I think it would be received well. I am currently working on a web project like this. Users receive 21 cards at sign up. Each match is 2 player, each player plays 3 cards, whoever ends up winning receives the losers 3 cards. Additional cards can be received through a faucet type set up once an hour, or purchased with btc from other players. Coming up with all the different cards and their attributes is a timely process, the coding has been pretty straight forward so far, but once I want to add additional features I'm sure I'll run into some walls. I think I'm going to call it Blockness, like the lochness monster, but block from blockchain... Anyways I'm at least a good few months out from releasing anything worth sharing. I've just been doing this in my free time, not even sure if I'll ever end up finishing LOL.
1739  Bitcoin / Bitcoin Discussion / Re: HODL, HOARD your cypto GOLD! All Hail the Hoarders! on: February 08, 2015, 04:54:49 AM
I was one of the silly newbs that bought in late 2013 near the ATH. Despite the constant price dropping, I've been buying every paycheck for over a year now and hodling as much as I can. The amount of support, infrastructure and validation from companies like Overstock and Microsoft out-weighs the price performance. I've lost some to trading and gambling, but for the most I have just been building up a stash. It's only a matter of time before demand goes up again. The occasional visit to the bitoinrichlist.com is a good reminder that there aren't even 250k addresses with >1 BTC. We all know everyone has more than one address, so it would be safe to believe there are much less than 250,000 people with >1 BTC. Sure some people could have 0.3 on four different addresses but I think it's more likely that people who split their balance up among multiple addresses have larger holdings.

When will it be?

I second this question, when is this happening?
