Doesn't have to be. If a lot of people want to pay in Bitcoin, they pushing the price up.
That's just free market. Only reason why it is this high, is because a lot of Bitcoins are not in circulation right now. Maybe as high as 80%.

Yes, you don't have to download the whole block chain.
But I don't know if it's really safe, I remember reading that it should be with future light weight clients.

The block chain grows with approximately 30MB per day. https://blockchain.info/nl/charts/blocks-size
But when your computer is not very fast, it also takes some time to verify and index the blocks if you start up your client again.

Nowadays the only way is to rent hashing power or to buy ASICs.
Otherwise you just have an electronic heater.

Depends if it becomes 'the way to pay'. If it has so much advantages to use it over other currencies, everybody would want to use it.
Then I would say yes.

If it only stays in the realm of speculators, maybe. But then it will be too volatile and in the end never succeed, because then it's really a bubble.
The market cap of Bitcoin is about 10 billion dollar, but when everybody would sell it, it would turn out to be worth a lot less.

But I really believe it is here to stay, because it is a great concept and the innovation has just begun.

BTW, you don't have to own 1BTC to participate in it. A lot of people are scared by the price of 1BTC when introduced.
I know it's psychology, but it is just a random unit. It is now time to use mBTC I think.

The easiest thing to do is just store your private keys on a (or multiple) USB-stick(s).
You can practice with a small amount to make sure you can do it.
It takes some reading into the details though.
Physical coins are a hassle.

Doing that to stay anonymous isn't totally security proof I think.
Someone putting a lot of effort in it, can still see that it's you. That is, if there aren't to many people withdrawing the same amount.
That is why the shared send was invented, but that also only works if there are a lot of people using it.
Maybe somebody else has a better understanding of blockchain.info's shared send?

Use something like this.
You will see that you need a much higher hash rate to make any profit.

Edit:
Never mind, for an alt coin it can be profitable.

I used it once with a smaller amount than 0.2BTC. It went through like a charm in under a minute.
But I guess they have good reasons to give you that warning. But I advise you to do only such things with your money if you can afford to lose it.

Good for you, always nice to read that Bitcoin is doing something good in somebodies life.
Pfffff, luckily you didn't post that annoying to the moon guy.

Ah okay, thanks. I see I was far too lazy searching. So it's disabled for security reasons. Too bad, it would be a nice personal touch to the accounts.

I can't seem to insert an avatar. I'm trying to insert one with an URL, but when I press 'change profile' the text field is just empty again.
Is it because I don't have enough posts yet, or something else?

People are always afraid off what they don't know. They were afraid they couldn't breath when taking the first trains, because of their speed (40km/h I think).
But when they see that other people are just fine and even have advantage of them, they will clime aboard.
When the idea is good, it will eventually become a success. If not, it was fun as long as it lasted.

I have a Jalapeno, and it does mine 0.0026 BTC in the last 24 hours. That's about 2 dollars a day.
BTW, that one you saw on the internet is way too expensive. When I bought it, it was 150 dollars.

That website is awesome!!!

I like this analogy. It's somewhat longer though.

Yes.

You have to offer something, can also be some page where you collect all websites who are using Bitcoin and categorize them.
That only cost you time to find them, but I'm afraid there already are a lot of them.

So we get there earlier because before the difficulty is adjusted, we mine a few blocks too many?
Then practically yes, but sort of theoretically no? Blocks are only faster generated because the difficulty is only adjusted every so often.
Correct me if I'm wrong.
