Depends on priority. Which in turn depends on number, amount and age of inputs. (Read how exactly here or here).

1) May get confirmed in next block.
2) May get confirmed in a while (2h to a week).
3) May never get confirmed.

You can try to send the same funds again with a fee included, rendering the previous tx a double spend. Don't think that's possible on Blockchain though.

Fungibility. Don't mess with it.

There is a chance the USD will drop in value 10-fold or more, which could cause BTC/USD to go up maybe squared that.

Awesome to see you go ahead with this.

You can pay less fees on your tx btw, a fifth of that is enough, assuming you don't do this intentionally.

If you have access to free electricity mining can be very profitable. I don't advocate stealing electricity, abusing your uni or work campus or violating fair use policies on rentals, but that's the way it is.

2. Makes you a terrorist. Rather be gay in Russia than a terrorist in the US of A

Awesome poll options when 90% of users are 0-10 and another 9% are 11-100.


Lets see how many 1m+ we can get 

I don't think moving the radix will work.

More realistically create a good name for mBTC and start using that as the primary unit of reference.

I think the 6 minute wait is lifted after some level of activity.

Different methods are available, yes

The site is pretty solid.

There are only unspent outputs.

I guess just embrace the fact that crypto is making it into collective consciousness. Anti-BTC propaganda.. you should write headlines for the sun.

I lol'ed

Such lines. Very prediction.

In the end you are not getting around storing the necessary bits of entropy, although smart methods may make it seem like less to memorize.

Good. No more dirty bills being passed along while not giving up anonymity like using a card.

Started at 1%, is at 6% now. Think that's a comfortable spot for me. At 10% I'll start selling.

I couldn't have guessed you meant that

It's a fair point, but I don't think the total alt-hashrate is that significant? If there was an attack on BTC of this kind Im sure it wouldn't be 1) obvious and  2) gradual and 3) close in terms of hashrate.

1) If I'm trying to become the 50%+ hast rate owner, I do so by slowly, by adding nodes legitimately. I may buy a mining pool or two, or just gain access to them. Then just wait for the right moment to change the protocol I use.

2) Once I have enough hast rate, I'm not releasing a bit day by day, so people notice empty blocks or a growing orphaned chain that someone keeps building. I suddenly change from normal mining to destructive mining.

3) I won't attack with 51%. I will attack with 55% or 60%, so even if everyone quickly goes to max hash by mining on CPU and switches from alts, I still keep over 50%.

bitcoinharn.de

they make a chain which includes no tx. they will have the longest chain, so your block which has tx in it doesn't get into the chain.
you don't seem to understand the meaning of 51%

market cap is just a measure. it bears no relation to any real life value. saying you can attack a 10 billion market cap with a 10 million investment compares two unrelated values; both are in USD but they are still not comparable. bitcoin has a market cap of 10b, but that does not mean that it is worth 10b.
