Advertising Just-Dice and then linking to another site... hmm... seems legit.

Welcome! Let us know your thoughts on where the protocol can be improved. Personally, I spend quite a bit of time looking at alt-coins, mainly to see what parts of bitcoin seem to be targets for improvement (blockchain compression, mining costs, faster confirmations, and so on).

Again, welcome to the forums!

It is str = nonce:client_seed:nonce. Use hmac512(str, key), where key is the server string.

You must use a HMAC (SHA-512). The lucky number is derived from a message authentication code, not the standalone SHA-512 algorithm.

I'll be honest: I've met some of the most intelligent, wise, and profoundly committed individuals on the forums. Some of them truly want to advance the best principles and technology of bitcoin. There's a polar opposite to this group: I've observed some of the strangest, creepiest, and otherwise nutty folk that have created a negative counterculture. At least - for the most part - these individuals tend to gravitate to certain sub-forums.

In my opinion, it could easily happen. Hopefully, the increase will reflect a stable, fair market price and encourage businesses and trade to adopt bitcoin as a medium of exchange, rather than volatile speculation or pressure from nefarious influences (for example, Cryptolocker).

Welcome to the forum, David!

If you go to your Watchlist and click on 'Edit Watchlist', you should see topics that you've posted or replied to. I use it to look back on topics I've started. Occasionally, I have prune the list to keep it from becoming too large.

This may not be the best way (I'm not certain), but it's how I view my topics. If you discover a better method, please let me know.

Best wishes!

Good luck with the mining. Please let us know about any achievements!

After receiving a few cents worth, how much have you spent in electricity?

Welcome to the forum, guillem3010!

Unless you are willing to commit some serious resources into mining, you may find it less risky at this point to speculate on the coins themselves. Depending on your location, you may wish to examine other exchanges too, since each may have different bid/ask prices. Additionally, Mt. Gox has been encumbered with issues with the United States government and may not be a riskier exchange.

The main problem with mining is that it has drifted away from a hobby enterprise to a more professional one (that requires more advanced, and more expensive mining equipment). One real issue is that some companies have failed to deliver mining products in a timely manner, preventing end-users from achieving real gains on the equipment before they become effectively obsolete (due to more advanced mining equipment and difficulty increases).

Please let us know if you have additional questions. Good luck!

Mondy, I am sure fildza is just teasing. Everyone starts somewhere, and since you were brave enough to post your question, I'm confident there have been other people who have asked the same question. Hope it ends up working!

Wow. I didn't realize that Mt. Gox was diving that quickly.

If you have free electricity, you can try mining with a graphics card, but the probability of success will be quite low. You can still join a pool, but your returns are expected to diminish greatly over time. That is, of course, unless you have a unthinkable number of graphics cards that you picked up for free as well.

I was looking at Chronic Unlocks for unlocking information and noticed they listed the iPhone 5S, which is obviously manufactured after the cutoff date. It must just be a United States thing, right?

You may have some luck visiting howtobuybitcoins.info. You can also find a local exchange where individuals around you will sell them. I have had success with this in the past.

Be very, very careful about purchasing coins from other forum members. There are educational materials posted throughout the boards (the ones in the 'Scam Accusations' sub-forum come to mind). They are incredibly helpful and will mitigate your exposure to cons and unscrupulous individuals.

While advice from forum members may offer insight, you should probably consult an experienced tax attorney. At least in my local area, most attorneys will answer brief questions for free. If not, you can always visit Avvo and see what the lawyers there believe. I asked my attorney something similar some time ago and was surprised at the answer.

Great! Let me know how I can subscribe to keep up-to-date on your work.

Welcome! I'd like to know what Blue Furies are as well (update: mining hardware).

You never know, it could one day take off, but I probably wouldn't spend too much time going after alternative cryptocurrencies. Bitcoin has enough brand awareness at the moment to fend off against alternates.

I have never had any issues with BTC-e. I also agree with what others are saying: if you buy them locally, you can sometimes score a better deal. Once, someone sold me bitcoins at 20% below spot, and the price was relatively stable. Good luck!
