Be careful what you wish for.
Last time a major bank failed it spread around the world, next time it could be worse.

If there was a worldwide crash & economic crisis we would all be rich by owning bitcoin.

Bring it on I say.
Would we? How had BTC performed on the last economic crisis? Oh yeah Bitcoin wasn't around back than, so you have no fucking idea..
Good luck feeding your family with your bitcoins, when you have lost your jobs and homes.
Bitcoin didn't move an inch during the Cyprus crisis, the recent Chinese stock drop nor during the Greek referendum.

Bitcoin may not rise during a crisis due to poor mainstream adoption, but it certainly won't fall.

Bitcoin will not cause the end of public debt. In stead of fiat, government can borrow bitcoin to spend. But it prefers not do this. It will borrow fiat and inflate away the debt.
If people have switched to Bitcoin then further printing more fiat would cause hyper inflation really fast.
In a Bitcoin world governments will never be able to borrow money in a realistic sensible manor.

The jig is up, no more free money for people who don't deserve it.

In a Bitcoin world debt would be much lower for the simple reason that Bitcoin itself would always appreciate as long as the economy did (or coins are lost).

In order to get a loan you would have to have a very serious project.

I think this would make the world better as people would try to save instead of spend and investments and loans would be more sensible.
I think that would be very healthy for the world and its people Smiley

Of course Keynesians would prefer more debt, more spending, more waste and burning the world if that is what it takes for more GROWTH!!!!

I have designed my own NFC Bitcoin card.

The NFC implementation is much better than that of the banks I believe:
What the card does is to store the addresses you pay to. Once you have paid someone twice before you can pay them by just swiping.

Because I use addresses in this way users won't have to worry about wireless pick-pockets! (because the thieves addresses wont be trusted)

I think mixing bitcoin and purposely trying to own bitcoin anonymously are likely to link with illegal activities. This should be discourage.
Right and using HTTPS makes me a terrorist right?

What a brainwashed statist statement.
26  Bitcoin / Bitcoin Discussion / Re: Guys... I'm having this feeling again on: October 29, 2015, 11:25:22 PM
I do not have much more than one BTC, but somehow I feel safer having it on coinbase than locally on my pc. My pc can be screwed. You say "do backups", but the backup may get stolen, you can apply many other security measures, but that makes holding your BTC rather messy and uncomfortable.

I would go through all that pain if I held 10 BTC perhaps, but not now... for the time being.

I kinda agree with you here, but it also depends on how much 1 btc  is worth to you. If you can live a month of off it in your country, I wouldn't be so comfortable as if it is only a fraction of the normal living costs.

It isn't too much effort to make multiple backups right? Also, physically stolen back-ups are not really that common I guess, as long as you don't tell everybody that you are storing bitcoins at home.

I wish they would just build in decentralized mixing in all the wallets.

Pools of 3-4 wallets take turns mixing so each wallet does the mixing in one round. This ensures that at least when your own wallet does the mixing it will be honest.
The members of the pool you participate in should change for each round if possible.

This would be very simple to do and it would make chain analysis impossible. We don't need super fancy algorithms that no one understands/implements well.

29  Bitcoin / Bitcoin Discussion / Re: [Poll] Is Fungibility (and therefore privacy) an issue with bitcoin? on: October 25, 2015, 12:21:40 AM
It won't matter. Bitcoin will succeed even with sketchy privacy. Any trivial mixing will be enough.

Governments can't crack down on massive movements, only small individuals and organizations.

Case in point: Torrent, its illegal but they can't stop it although they could easily trace people's IPs.

A gram of gold is 0.035274 oz. A gram is the minimum unit commonly traded. The minimum bitcoin transaction is 0.0000543 BTC and should have a name as well. This minimum unit is most commonly used for creating contracts.

5460 Satoshis in fact, not 5430.

P2P markets like Open Bazaar that cannot be shut down and reward halving are two strong indicators to me that the price could go up.

Usability and adoption have also grown during the past 2 years lull.

At the very least 230$ seems to have become a very stable floor - stable currencies are seen as strong and usually increase in value during crisis.
32  Bitcoin / Bitcoin Discussion / Re: We need the bitcoin foundation to fix the blocksize problem on: October 03, 2015, 11:20:19 AM
I still believe the Foundation may prove useful sometimes in the future. I understand many people distrust them, but they now have an opportunity to regain some trust, so if they're smart (maybe they're not), they should seize it. Besides the blocksize problem, another issue is that the BTC community is divided. I could invest more money into BTC, but that division is telling me to wait till things are settled.
I'm on the board of the Danish Bitcoin Foundation - an affiliate of TBF.

They are not answering our emails anymore, we don't have any contact person with them and their membership system that we integrated into our site is down/not working.

They are pretty goddamn dead it seems to me...

I had found this great Stratum wiki here:
http://electrum.orain.org/wiki/Stratum_protocol_specification

Now when I go to that link it redirects me to the pornhub web site I kid you not - what gives? Sabotage?

For all the talk of documentation in posts / anywhere I'm having trouble finding out how this works and the expected syntax for commands.
Can anyone help with this problem for instance:

35  Bitcoin / Bitcoin Discussion / Re: whoa there BIP100 at 61%?? Let's talk about this first... on: September 15, 2015, 03:49:49 PM
Jeff clarified this on the bitcoin-dev mailing list[url]:

Quote from: jgarzik
Quote from: achow101
I have been reading the pdf and one thing I can't figure out is what you mean by "most common floor". Is that the smallest block size that has a vote or the block size with the most votes or something else?
20th percentile, though there is some argument to take the 'mode' of several tranches

I think a better implementation/description would be:
"50 percentile median of votes - done". (not average - MEDIAN)

That way if its broken, well you are already under 51% attack and need to do something anyway.

There are other problems with taking the median though.  For this to be effective we'd need to assume that a majority of the blocks mined will vote for a limit deemed good for Bitcoin's long-term health.  However, a miner's financial incentives are not particularly well-aligned with that goal[...]
Thanks for answering me Teukon!

You're right about medians... we don't really have many great options on the table do we, everything seems to have a catch!

If BIP100 uses the 20% percentile I would guess it would be coded so 1mb is still the minimum limit - so that takes care of the 20% attack setting it to 0mb.
Can anyone confirm that or is it just common sense?

If so I might still like BIP100 even if not perfect.
36  Bitcoin / Bitcoin Discussion / Re: whoa there BIP100 at 61%?? Let's talk about this first... on: September 12, 2015, 09:19:11 AM
Just want to add my 2 cents/ask if I got it right.

This I believe is the central core of BIP100, copied from the documentation:
Miners vote by encoding ‘BV’+BlockSizeRequestValue into coinbase scriptSig, e.g.
“/BV8000000/” to vote for 8M. Votes are evaluated by dropping bottom 20% and top
20%, and then the most common floor (minimum) is chosen.

(link)

The way I understand it, it means this:
1. The 20% lowest and highest votes from miners are dropped.
2. "The most common floor is chosen" - a floor function converts decimals to integers, so a vote for 8.9 mb becomes a 8 mb vote. (Is that correct?)
3. In the case that there are equal votes for say 7mb and 8mb the lowest (minimum) floor is chosen - so 7mb.

Honestly I think that sentence is pretty unclear. What if there are floors 9, 10, 11, 12, 13 with all "one" vote each and I come in with 20-30% of mining power and vote twice for 0?
Under that definition my floor of 0 would win right?

Can someone spell it out for me?

Alternative understanding:
Block size is set to be the lowest 21 percentile vote - not safe!


I think a better implementation/description would be:
"50 percentile median of votes - done". (not average - MEDIAN)

That way if its broken, well you are already under 51% attack and need to do something anyway.
37  Bitcoin / Electrum / Re: electrum api on: September 12, 2015, 08:28:37 AM
i want to make a market place with bitcoin escrow and need a api to get this done
as i know the blockchainn do not support multisig so plan to use electrum
is there anybody used it before?
my marketplace will use php and is there any guide on how to use its api?
many thanks
Just started looking into the Electrum protocol layer "Stratum" myself. The documentation sucks a bit, but have some links:

38  Bitcoin / Bitcoin Discussion / Re: Bitcoin XT has code which downloads your IP address to facilitate blacklisting on: September 06, 2015, 10:29:03 AM
XT has lost my support. Not so much because of this - TOR is useless anyway if it can't protect itself.

No XT has lost my support because:
1. The consensus threshold is too low. 80-90% is better than 75%.
2. XT introduces many new things, the block size consensus debate is too important
for distractions.

BIP 100 holds more promise I believe - although I think it should operate with the requested blocksize of the 50 percentile median rather than the 20 percentile.

BIP 100 is simple and solves the problem elegantly - XT is complex, muddled and makes assumptions 20 years out.
39  Bitcoin / Development & Technical Discussion / Re: Is this a legal Bitcoin transaction? on: August 15, 2015, 08:12:44 AM
Can I have a single Bitcoin transaction with several outputs where two of those outputs are to the same address?

Can I have both these outputs in the same transaction?


amount1: 1.2 address: 1Ant11EeZU7V49puUeLsDvbUUi9HS5xSg2
amount2: .2 address: 1Ant11EeZU7V49puUeLsDvbUUi9HS5xSg2

Totally legal and there is nothing wrong with it.

There can be cases where this is desirable also, for instance if you need confirmed outputs to spend, it helps you to create more outputs you can spend - so you don't have to do just one transaction per hour.
40  Economy / Speculation / Re: Only $360mio of inflow needed to keep current price and reach next halving! on: July 28, 2015, 11:29:28 AM
For some reasons I start to think that miners would give up on mining after Mining block reward , I mean they was earning 25 BTC and they would be earning 12.5 will they still making profit with all electricity they are eating ? If not is it a possible theory that they will stop mining and Bitcoin will eventually die ?  Undecided
Bitcoin is the largest super computer in the entire world.... x500-2000!

I think we would be just fine if there was 100 times less mining.
