On the other hand, what if you look at pets.com. webvan, etoys.com, @home, kozmo.com, flooz.com, boo.com, mvp.com. go.com, kibu.com, and govworks.com?

Many said that they were undervalued, and then they failed.

I don't think your comparison is any more "fair" and any less arbitrary than the comparison of the values of 95,084,257,000,000,000,000,000 atoms of gold to 100,000,000 satoshis. Maybe that is your point.

I think the comparison of the total value of all the bitcoins ($34,460,900,000) vs. the total value of all the gold ($8,943,770,600,000) might be more useful.

The more people expect the price to continue rising, the more it is likely to crash.

The generation of new coins by a miner is part of the validation rules. Any miner can change the rules locally, but that will result in their exclusion by everyone else.

An alt coin can have whatever rules its developer wishes.

Here is the best advice you will get here:

You know very little about those coins. Don't invest in something you don't understand.

It depends on the level of security you are looking for. Bitcoin is nearly instantaneous if you don't require any confirmations.

If you do require confirmations, keep in mind that it takes many Ethereum confirmations to equal the security of a single Bitcoin confirmation.

You must send the full amounts of the inputs. If you don't actually want send all of it, the remainder must be sent somewhere. Your wallet creates a new ("change") address and sends the leftover amount to that.

It's a Spoonerism for "hold", originally used in this drunken rant's title: https://bitcointalk.org/index.php?topic=375643.0

Or more recently, a backronym for "Hold On for Dear Life".

There is no "settling" and no balance. The balances your wallet shows you are computed by the wallet for your convenience. The balance for an address is simply the sum of the outputs using that address that have not yet been used as inputs.

Time is not relevant. Your 0.75 BTC transaction will be the same whether it is made immediately after the two 0.5 BTC transactions or 100 years later (assuming there are no others in between).

Transactions work with inputs and outputs. The output of one transaction becomes an input of another transaction.

Here is a long example:

Let's say that somebody sends you 0.5 BTC twice, for a total of 1 BTC, and you want to send 0.75 BTC to somebody. Your wallet will construct this transaction:

Inputs: 0.5 BTC, 0.5 BTC
Outputs: 0.75 BTC, 0.2499 BTC
(fee paid is 0.0001 BTC)

After that transaction, your wallet has 0.2499 BTC (the "change" from the previous transaction).

Now, you want to send 0.1 BTC. The wallet constructs this transaction:

Inputs: 0.2499 BTC
Outputs: 0.1 BTC, 0.1498 BTC
(fee paid is 0.0001 BTC)

Your wallet now holds 0.1498 BTC. Then someone sends you 0.1 BTC, so you have 0.2498 BTC.

Now, you want to send 0.2 BTC. You wallet constructs this transaction:

Inputs: 0.1498 BTC, 0.1 BTC
Outputs: 0.2 BTC, 0.0497 BTC
(fee paid is 0.0001 BTC)

The address shown by Mycellium is always new and unused. If bitcoins are sent to that address, Mycelium will then generate a different new and unused address.

If you need two new addresses at the same time or the mixed bitcoins are being returned to the same wallet, then you can set up a second account inside Mycelium (go to the accounts page). The second account is just like a second wallet.

I just feel that mixing coins provides little benefit in most cases. It depends on the level of anonymity you desire.

A trend describes the past. It cannot predict the future, except ...

Some people believe that a trend does predict the future, so they follow the trend and they help prolong it.

Unfortunately, most of those people will lose money in the end. It is like they are playing a hand of poker where everyone is bluffing and everyone knows that everyone is bluffing. The trend ends when enough people no longer believe in the trend and the price corrects. That's called a bubble.

For any kind of reasonable answer, we need to know which wallet you are using. Different wallets work differently.

A wallet stores your private keys and/or your seed in a file somewhere. Some wallets store that information in a file named wallet.dat. It is important to ensure that this information is both encrypted and backed up.

Some wallets encrypt the data by default with a password that you provide. BTW, a password is not the same as a seed or a private key. If the wallet you use does not store the information securely, you should use a different wallet.

Some wallets (such as Bitcoin Core) have a backup feature. It might be better to use that feature to back up the wallet's information rather than doing it manually.

I recommend Airbitz. It is designed to be both secure and easy to use. It has a lot more features than breadwallet and is easier to use than Mycelium.

Just look at the housing bubble. That was caused by millions of ordinary people buying houses that they ultimately could not afford.

A bubble is caused by speculative buying by many small investors. It may be triggered by whales making large buys, but it isn't a bubble until it becomes mainstream.

We are not there yet, but it will be time to exit when you see waves of newbies talking about how much their bitcoin investments are worth.

You are assuming that the price will continue to rise. That is not guaranteed, so selling is not necessarily lost opportunity.

Selling may be the way to maximize your return, but it depends on the risk of holding.

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.
