I got this PM from OP:

Quote
here's some clues. these are the ones i've seen on the document which are currently Right
1 5Juu2
2 2CkB3
4 EcyH9
5 dypNh
7 gh6RQ
8 wwbo5


Also here's a Clue ''sometimes going back will refresh your memory''

Not sure if there's any significance of him using two single quotes (') instead of a double quote (") to quote that clue.

To be honest, without any error checking, I am not able to go further. As any answer could be totally wrong. And we could just be barking up the wrong tree trying to think of another solution when we already have the right one.

OP, I think it would be useful for you to confirm when we have found the right solution for any question.
283  Economy / Games and rounds / Re: Bitcoin Cipher/puzzle - 0.56 Prize ! Bitcoins on: August 10, 2015, 04:48:28 PM
This puzzle is especially tough because private keys are a bunch of random letters and numbers. There’s no error checking in the solution, so you can easily come up with multiple answers to each part and you wouldn’t know which is correct.

286  Economy / Games and rounds / Re: Bitcoin Cipher/puzzle - 0.2 Bitcoins on: August 07, 2015, 10:47:11 PM
then we get
Quote
5hee2
which looks like the beginning of a private key.
The second character in an uncompressed private key has to be one of H,J,K. If we use 'XoXo' from the hint to indicate case, we get 5HeE2.
If you decode 5hee2 with the same shift cipher as the hint, it comes out as 5juu2, and 5Juu2 would also be a valid start for a private key. Also, part of the hint was "UU EqUAl SmAll lETTErS", which further points in this direction.

Bingo. I think that's it. the hint is actually all upper case "UU EQUAL SMALL LETTERS"
287  Economy / Games and rounds / Re: Bitcoin Cipher/puzzle - 0.2 Bitcoins on: August 07, 2015, 05:08:18 PM
I think "REPLACE 1 WITH 2" means to swap the 2 positions.  1's answer is 2CkB3
288  Economy / Games and rounds / Re: Bitcoin Cipher/puzzle - 0.2 Bitcoins on: August 07, 2015, 09:42:03 AM
Ok, here's what I've got so far: https://docs.google.com/document/d/1W9T8PP59Bib0IA8CJ1_W4WngvQZ2j7OL-2sJen0y1wg/edit?usp=sharing

289  Economy / Games and rounds / Re: Bitcoin Cipher/puzzle - 0.2 Bitcoins on: August 06, 2015, 05:32:42 PM
I think each answer is 5 characters that combine in a private key.
290  Economy / Games and rounds / Re: Bitcoin Cipher/puzzle - 0.2 Bitcoins on: August 06, 2015, 05:15:55 PM
This puzzle is awesome. Kudos to the OP. I figured a few of these. I'm going to first post some hints before giving the answer away. No guarantee my answers are correct though! Smiley

291  Alternate cryptocurrencies / Altcoin Discussion / Re: I thought litecoin was more secure. on: July 06, 2015, 06:26:08 PM
So question to you mr coblee, is litecoin more secure then bitcoin?

No, it takes less $ to 51% attack Litecoin than Bitcoin. But 1 confirmation on Litecoin is way more secured than 0-conf on Bitcoin. 4 confirmation (10 mins) on Litecoin is arguably more secure than 1 confirmation (10 mins) on Bitcoin because of Gabler's Ruin, but I have not done the math for that.
292  Alternate cryptocurrencies / Altcoin Discussion / Re: I thought litecoin was more secure. on: July 06, 2015, 06:08:23 PM
I'm going to have to run the numbers when I get time but I'm interested to see how things have changed over the last year since coblee wrote the above quotes.

The calculations are a bit different when there are merged mined coins. Since the rewards are combined for merged mining, the security is relative to the combined value produced by the coins. For the sake of simplicity, you can ignore the merged mined coins because they add very little to the total rewards.
293  Alternate cryptocurrencies / Altcoin Discussion / Re: Bitcoin is in deep trouble. Litecoin to take its place soon. on: July 05, 2015, 06:36:23 AM
What is very irresponsible is hard coding into the protocol of 28tps after observing the debate in Bitcoin going back to 2010. The hard blocksize limit is precisely what has got Bitcoin into its current problems. This issue remains in Litecoin and if, as it is likely, Bitcoin deals with this issue the limitation will still remain in Litecoin. The Litecoin community has missed the golden opportunity by ignoring this issue.

Litecoin's blocksize will last us a few more years. If we do decide to change it, we likely won't run into the same political nightmare that Bitcoin is dealing with today. This is because members the Litecoin development team have very similar vision for the future of Litecoin.

The current direction that the Litecoin development team is thinking about is to create a fee marketplace. This, in our opinion, is a better approach to the blocksize debate than to recklessly increasing the max blocksize without full understanding of the consequences.

295  Bitcoin / Bitcoin Discussion / Re: Litecoin v. Bitcoin on: April 29, 2015, 01:33:44 AM
I recommend litecoin more because it's faster and cheaper and also better distributed and with smaller blockchain.
There are lots of coins more fast and cheaper than litcoin, is that means these coin better than litcoin /bitcoin? The answer is absolutely not.

That's what many people don't seem to 'get': If an altcoin has shorter confirmation-/block times, the actual safety a block adds to a transaction is smaller. Shorter block times mean that mining a block is inherently easier than it would be at the same difficulty on the Bitcoin network. Also, the smaller total blockchain would certainly bigger if Litecoin overtook Bitcoin as the primary cryptocurrency.

That's not 100% correct. More blocks does add extra security. Satoshi's original Bitcoin paper talks about this gambler's ruin. Here's a bit more on it: http://www.reddit.com/r/litecoin/comments/1cssqr/the_math_why_litecoin_is_more_secure_than_bitcoin/

Of course, money spent on hashpower affects this also. Waiting for 10 minutes being protected by $1M worth of mining hardware is much less secure compared to if it was protected by $1B worth of mining hardware. So it's really hard to compare security between Bitcoin and Litecoin. Practically, Litecoin is protected by less money than Bitcoin, so it's good enough to secure smaller transactions.
296  Bitcoin / Bitcoin Discussion / Re: Litecoin v. Bitcoin on: April 27, 2015, 04:27:15 AM
In all honesty, it seems to me that a cryptocurrency with a $50 million marketcap is important enough to have a lead developer that makes the job his "title role" and all other endeavors secondary.

But I guess working for a semi-famous boss that hates Altcoins makes it hard to say anything other than "development is not needed". If this had been the attitude of Henry Ford we'd all be driving around in fancy horse carriages.

Development is going along just fine: https://litecointalk.org/index.php?topic=25306.0

If someone thinks they can do a better job than Warren at leading Litecoin development, please raise your hands. Who are you to criticize us for not spending 100% of our time on Litecoin?

Being the creator of Litecoin, I believe I have the best vision about how to help Litecoin succeed in the long run. And that's working at Coinbase to first help Bitcoin succeed. Litecoin was created to complement Bitcoin. If Bitcoin fails to become adopted by the mass, only a fool would think that Litecoin (or any other cryptocurrency for that matter) will succeed where Bitcoin failed. Adding the latest snake oil feature to Litecoin only helps Litecoin in the short run. Maybe if I spent 100% of my time the past 2 years working on Litecoin and adding gimmicky features, there might be a 20% increase in price and users. I think even that is optimistic. And that only gives Litecoin a short term pump in price.

I want Litecoin to succeed long term as much as anyone else. Of course, there's a risk that by not pumping Litecoin today, another coin might manage to take over the 2nd position, and that could spell doom for Litecoin. But that's a risk I'm willing to take. My main goal is to help cryptocurrency (Bitcoin, Litecoin, and every other coin) succeed. I'd rather live in a world where Bitcoin became the dominant currency and Litecoin has died than in a world where Litecoin is still the #2 cryptocurrency but very few people use Bitcoin or Litecoin.

Coinbase exchange just started doing fees. (0.25% maker)
So you can start counting the trade volume.

is that only on the maker side of the trade or on both sides?

Only on taker side

Litecoin is a joke

You know Litecoin is a joke when it's lead developer and creator stops developing for it:

The fact that Charlie Lee works for Coinbase, probably the largest Bitcoin based company, is a joke in itself.

You know Bitcoin is a joke when it's lead developer and creator stops developing for it. :p

The "there can only be one" camp of Bitcoiners do not understand that altcoins supporters don't necessarily think that any altcoin will overtake Bitcoin in value. I can't speak for everyone, but I believe that Bitcoin will always be the "one" cryptocurrency, the crypto reserve currency.* But there will always be room for a few more cryptocurrencies that are adopted widely just like Bitcoin. These cryptocurrencies will have independent economic models and not pegged to Bitcoin and will have a free-floating market price. As toknormal said, the market has already decided that altcoins have a future. The market is smarter and more efficient that any one of us. You can say "shitcoins are dead" a million times, but that doesn't change the fact that Litecoin has a $60M market cap and that people are willing to trade them at ~$1.80 a coin today. This doesn't guarantee that Litecoin will survive in the long run. But one thing I know for sure is that there will always be altcoins.

For those that think Bitcoin and sidechains (pegged Bitcoin) will cause market cap of all altcoins to go to 0, do you also think that all countries should adopt the USD or peg their currency to USD?

* And that is why I work for Coinbase.

Did I really donate 3BTC to you? Can I have it back? Tongue

It's weird that you would remove Litecoin because you didn't get any donation in LTC. Have you considered that a lot of Litecoin users prefer to spend BTC in the past year because they feel like LTC has more upside?

Anyways, including Litecoin was only a few line changes. I'm quite disappointed that you would do this to make a statement. I guess I won't be using CoinMap anymore.
