Bitcoin back over $6000. It will recover but may be a long timescale.

IF it recovers, it will be super quick.

Buy now (BTC at $6,117)! You heard it here first...

From a technical point of view, that low down to $5,500 looks like the final low. A quick, deep dive down with a quick, steep recovery is always what you want to look for at the end of corrections.

Fundamentally, the BTC blockchain will start moving again two hours from now. That will bring back confidence. Additionally, it looks like BCH has found its short-term peak.

BTC and BCH will probably co-exist in the future. If you buy now, you will have bought at a great point to enjoy the fireworks to come: The year-end-rally.

Still a lot of insecurity in the market, but not that much danger anymore... buy now, when there is blood on the streets!

You can't do it with Bitcoin but there are Ethereum apps which allow you exactly what you described. I think you can do it with Status (SNT) and several more apps.
Check out Byteball too.

Thanks, looking for a way to do it with BTC though. I'm not gonna choose my crypto after its ability to send a message with a transaction. Wink

Bitcoin is not a messaging system.

However, the OP_RETURN code was added so that some data could be embedded in the transaction outputs if someone wants to.

None of the standard wallets provide a user interface for embedding data, nor do they provide any method for viewing any embedded data.  This is because Bitcoin is not a messaging system.

However, there are services that will charge you a fee and will create transactions with embedded data for you.  Most of those services will also display that data on their website.

Yes, I get that Bitcoin is not a messaging system. I was asking out of curiosity, and also to maybe in the future mark certain addresses as proof for tax reasons. It's not good to spam and congest the network, I know.

Which services would do that, can you name some?

And btw, I applaud you for restlessly answer questions on this forum and educating people. Bitcoin needs people like you, so thanks!

The message that Satoshi included in the Genesis block is actually part of the Coinbase transaction of that block. Specifically, in the input of any Coinbase transaction, you can include whatever data that you want. Satoshi chose to put a string there. So if you want to do the same thing, then you must be a miner and set whatever you want in that part of the coinbase transaction of your blocks.

There are other ways to embed data in transactions. You can use an OP_RETURN output which allows you to make a provably unspendable output that has arbitrary data in it.

Thank you! Only possible for miners, I see.

Would you mind explaining how I can use an OP_RETURN output? Do I have to run my own node in order to do that? Non-technical person here...

A message e.g. like the one Satoshi sent with the Genesis block: "Chancellor on brink of second bailout for banks."

Just curious how to do this as a normal user.

Re: Ledger Nano S among top Electronics accessories

on 16/10/2017, 16:40:36 UTC
A bit off topic: I'm on the fence whether to buy a Trezor or a Ledger S. I know they are both good. BUT:

1. I recently heard that Trezor had some security vulnerability exposed (with its recovery seed, I believe). What happened there, and is this a danger for the future?

2. Once my device arrives, I want to test the recovery seed (pretend I lost my device, and use the recovery seed to recover my wallet). As I understand, if I do this with the Ledger, the seed and thus my device will be worthless afterwards; whereas with the Trezor this is possible without problems. Correct?

Any hints of knowledgeable people would make me a happy hodler!

I'm partial to Ledger, since I've had the Ledger HW.1, Nano original, and now Nano S.  

Trezor patched it in the latest firmware.  Physical access to the Trezor is required for that vulnerability.

As for testing Ledger or Trezor seeds, download these Bip39 files from Github.  Disconnect Internet and load in an incognito/private browsing session.  I like to boot offline to a Ubuntu trial CD, load up the HTML file, then plug in your seed to make sure the same destination addresses are produced.  Even the optional passphrase works.  Don't do this if you don't trust your computer.

Or, a more secure way is just to erase your hardware wallet, and start from scratch restoring the previous seed (takes a long time with spelling via button pushes).

Great, thank you!!

I would choose the second, more secure option, for my peace of mind. I knew you could do that on Trezor, but thought it wasn't possible with the Ledger.

Oooopsss... up to 13% again.

Bitcoin also went up in price, so there's that... many factors contributing to profitability, from difficulty and hashrate to exchange rate. I guess one can run calculations himself to check on what's happening Cheesy

Right, I didn't think of that.  Smiley

Those blocks are almost empty. Does that have any effects on difficulty or how much the miners are earning?

Re: Ripple back on 3rd place! Bitcoin Cash fell of the cliff!

market cap is 100% meaningless!
it is just multiplication of price and supply. and it is with all the 4 coins after bitcoin until LTC.
the 72 million premine of ETH, the god knows how many billion coins of XRP and about 90% of 16.4 million coins of BCC has never reached the market.
exclude the fake coins of altcoins and let the BCC deposits open and people be able to deposit that 16.4 million (of course a very small portion of it will ever move) and then compare market caps.

as far as i am concerned litecoin is number 2 in that list so far.

Interesting. I was always wondering why people value a firm cap of supply so little about a coin. BTC has a firm cap, and with the halvings, lost coins, etc... it's guaranteed deflationary! With ETH, it's not even sure how many there will be on the market in the future, and one man could change the rules anytime anyways. Then, some clueless new investors even think BTC is 10 times more expensive than ETH, so ETH is still really cheap...

Can you tell me more about those pre-mined ETH coins, are these included in the official supply? Who has them, what's the scheduled plan? I have never heard about this.

Also, what about the XRP supply, can you shed some light on it? I know nothing about XRP.

Re: How high can BTC go? Fact-based, with the only graph you will ever need

I don't see Bitcoin as much as a competitor for gold than for Western Union. Remittances is, as of now, the field where Bitcoin really excels: The volatility is almost non-relevant - even in bear markets - as Bitcoin remittances take place in minutes to a few hours, and there are no international barriers (apart from prohibitions in, at most, a handful countries).

According to this article the yearly remittance volume is 500 billion USD. Bitcoin could capture at least half of it.

Obviously, it isn't that easy to say "now, Bitcoin can have a 250 billion market cap" (only taking into account remittances). An estimation would probably be based on the Quantity Theory of Money. But I estimate that there is a potential for Bitcoin's price to rise at least five times higher than today only if it is able to capture this market.


Interesting article. Half of all remittances is a bit much for me, but I could see BTC bite off a big chunk of the remittance market.

But: As fiat is only converted into BTC for a short time, and then converted back, would that drive the price up permanently and constantly? I guess you could argue that at any time xx remittances are needed in BTC.

Gold is used by the people for centuries.All the people without computer knowledge will trust gold,and believe  me,most of the people in the world don`t have a PC,which means that they don`t know anyhting about btc and most likely they will never buy and use bitcoin.

the people without computers don't have any effect on the gold price. that's set by people with computers.

once more of those people with computers realise what bitcoin is and can do then it's off to the races.

it's been nearly 40 years since gold's all time high. in the meantime paper gold has completely detached the price from any type of reality and there's more fake gold than ever. it's ripe to be superseded by young and savvy people at least.

I love the fact that this paper scam will not be possible with BTC. If you want to mass-dump BTC, you have to BUY it first, ha ha!

Also, how did you calculate that all-time high?

There`s plenty of space for bitcoin to grow,but it`s wrong to compare it to gold.

It might make more sense to not take the number of people with a computer, but instead the number of people with an internet connection, which is about 3,6 billion people (and rising). That's pretty good. In the future, as people get more used to BTC, and younger people, who are more prone to adopt to new technologies, grow into BTC, I could see many, many people buying BTC instead of gold. Also, BTC historically brought a lot more gains than gold. Plus it's easier to store, hide and transport, etc...

Also, I only gave BTC 10% of gold, which is still quite a conservative number.

10% of gold may be a conservative number, but it's still a wild ass guess. Also while BTC has had a better yield than gold, it's still little more than a blip in the history of trade. Just as a caveat, I still like the odds.

Regarding most people never buying and using Bitcoin due to lack of computers or internet: Most people most likely will never buy stocks or gold either. People lacking access digital infrastructure even less so.

Totally, I agree with all of this.

I get what you are saying, OP. The ascent of the price was suppressed for some time because of the SegWit2x debate, and now it's resolved, shouldn't the price be much higher?

The price is already much higher than it was a short time ago at $1,900. Also, two reasons why it's not even higher:

1. August 1st is the big date in the head of the public. It's the date you can read about in mainstream media.

2. The hard fork is upon us now.

3. SegWit is not running yet.

I expect the price to rise steeply over August/September. That could start at the beginning of August, or maybe not before the end of August. But I think it will happen.

Median global computer ownership was at 38% in 2015, it's not hard to imagine it going to 70-80% in next 20-30 years. Which will mean that Bitcoin can easily become a gold of digital era, even if it won't scale into a currency level. And Bitcoin is more convenient for private storage and moving, it can be used anonymously, it can be hidden from all other people. Gold is valuable because it's scarce and chemically durable, nothing more, so Bitcoin can also be extremely valuable, because it's scarce and digitally durable.

I completely agree. 38%, right, that's what I meant when I said "let's look at the numbers." It can all be easily googled nowadays anyways.

How high can BTC go? Fact-based, with the only graph you will ever need

So we hear all of this clueless speculation based on fear or greed: BTC is too expensive already! It's too late to buy! It will go to $10,000! It will be worth a million in 10 years! Yada yada yada...

But where are the facts, the numbers? How do you get to these predictions?

Let's start a thread in which we try to see how far it could go based on actual numbers of other assets. Let's ask the question:

How much of which other assets could go into BTC?

Of course, that's speculation too, but it's educated speculation. I will start out with this very interesting graph here. It shows you the market cap of BTC and many other assets, visualized in little cubes, according to their size:

http://money.visualcapitalist.com/all-of-the-worlds-money-and-markets-in-one-visualization/

And yes, the graph is a bit behind, as the current market cap of BTC is not 5 billion anymore, but 44 billion at the time of this writing. Check the current BTC market cap here: https://coinmarketcap.com/

For example, the market cap of all physical gold above ground is roughly 7 trillion or 7,000 billion. So taking into consideration BTCs 44 billion market cap, BTC needs to go to about $4,300 in order for it to have 1% of golds market cap (that would be 70 billion). If BTC goes to about $43,000, it will have 10% of golds market cap.

So how much could it draw away from gold? 1%? 5%? 10%? 20%? Even more?

And how much could it draw away from stocks? Bonds? Derivatives? Other assets?

My opinion: If you do the math, you get to quite a staggering number, and you can see the huge upwards potential BTC still has. I could definitely see it taking a bit bite out of gold, let's say 10% at least, which would already let it go to $40,000. And I'm not even speaking of stocks, art, maybe even real estate and bonds here. So I think $100,000 per BTC is definitely possible, IF no terrible thing happens along the way (government restrictions, political wars within BTC, technical catastrophes, etc...). We will see.

Your guestimates, ladies and gentlemen? Which other asset classes do you think BTC could draw from, and why?

I will try to put the most interesting diagrams, observations, etc... into this OP.
