Yes, public information.

For example, in the past Blockchain.info has scraped Bitcointalk user signatures for addresses, and associated user names with those addresses. Like this: https://blockchain.info/address/1NhMCm8fYaHmVanKx33yhh1gfVW1DMBUjZ
I asked them to remove the link to me and they refused.

The premium for GBTC does not indicate "underlying asset value". It is simply the result of the lack of liquidity caused by the lock-up period for new shares.

This site is for discussing Bitcoin. It is not for earning or saving or storing or spending bitcoins. Just discussing.

You don't need to do anything special to get an address from Mycellium (or most other wallets). Every time you use an address, it generates another automatically.

Also, I don't think it is helpful to use a mixer in most cases.

There is no need to back up the keys themselves because they are generated directly from the 12-word seed. If you have the seed, you have all the private keys that the wallet will ever generate. I'm pretty sure that it true for all HD wallets, but you should check with the wallet developer.

OTOH, some wallets might also let you import keys that are not related to the seed. You would have to back up those keys if they hold bitcoins.

Of course trust is a factor (people with lower credit rating pay higher interest), but the primary factor is opportunity cost.

If I have money, I can choose to either invest it or loan it. If I loan it at no interest, then I have lost any money I could have made by investing it. If you want me to loan you money that I could otherwise invest, it is going to cost you.

On the other hand, if you didn't sell those bitcoins, you would have developed a debilitating heroin addiction and eventually died from an overdose.

So be happy you are alive and move on.

The user database was leaked 2 years ago.

No mention of Bitcoin anywhere in the article.

Option 1: Earn $2 (worth 0.00125 BTC) per hour at a real job. Use the money to buy bitcoins.
Option 2: Earn 0.0000125 BTC (worth $0.02) per hour doing faucets or spamming the forums.

Why is there even a question?

When Bitcoin.com mined a 1+ MB block because of a bug in their code, who was affected? When people found and exploited bugs in the BU client, who were affected?

You wrote, "in a consensus system with multiple major implementations, ..." My ideal is a consensus system without multiple major implementations. As I wrote earlier, there are 83 different implementation being used right now and yet Bitcoin is humming along. The real problem is that a few of them dominate the rest, and a person striving to make Bitcoin more robust would be working to eliminate the dominance of any particular implementation because that implementation is a point of failure.


It is true that an implementation is a precise definition, but is such a precise definition necessary? You write as if Bitcoin does not have a mechanism for resolving disputes between nodes, but it does of course.

Multiple implementations are necessary. If one implementation goes down or has a bug, then only the users of that implementation are affected. If there are many implementations then the effect of one implementation having a problem is minimal.

The fact is that there are already many implementations currently running. This site (https://bitnodes.21.co/nodes/) lists 83 different implementations that are currently in use. Unfortunately, they are mostly versions of Bitcoin Core, so they all tend to have the same flaws.

Also, there is an important flaw in the single implementation argument. Whenever the single implementation is updated, a new implementation that could create an accidental fork is published. You can't avoid accidental forks by using a single implementation if you want to upgrade it. In fact, there already has been an accidental fork caused by a Bitcoin Core update.

Bubbles are bad because the resources that a bubble wastes dwarf whatever benefits you may find.

It is a naive fantasy. Even if we could change the POW algorithm to be GPU-only, we would still get this:

You are posting on the wrong site. This is Bitcoin, you want to post on http://digitalnotetalk.org/.

I hope you don't plan on mining Bitcoin with your GPUs.

Mining is an advanced topic. Newbies should have a good understanding of everything else before tackling the details of mining.

Mining is an integral part of Bitcoin. If you destroy mining, you destroy Bitcoin.

TO THE MOON!

CRASH!
