Okay these sites dont entice you to subscribe or are they limited unless you pay at their paywall?

Any other good sites worth mentioning?

Trading view have pro and basic options but the basic free tier is enough for what you'd need starting out.

I'm not sure how much I'd trust signals myself you're better off loosely trying to find trading patterns or look into technical analysis.

Investing.com is free though and their sentiment analysis and historical rates might be interesting to look at. I wouldn't trade straight off raw data though.

1. There is no question about Fiat money (whatever it is $, £ or euro.) thats its losing it's value, so the question is.
I think we don't talk about Fiat only but talking about physical currency. Even if Fiat is no longer exist, we still have coins currency made from gold or silver or copper. So, don't worry about losing values of physical currency as the chance is almost impossible for me. In addition, we cannot use digital currency in all situation, how if there will be no internet. And still many other challenges or obstacles to apply it as a single currency.

Fiat currencies are always losing value... I don't think a deflationary model is the best idea but its not acceptable to say currencies don't lose value. In the past 30-50 years, most currencies are worth half of what they were previously worth in the developed world.

Most people use contact less payments for small purchases these days or at least cards and many stores here have moved to streamlining its use, if the Internet goes down, you're 6 minute queue is now 30-60.

Real Estate are commodities imo...

I've seen a lot of day traders using trading view and nothing but trading view... It seems very popular and has a lot of functions even on the free version. Some day traders will use their own (probably) software and their own analytics too to decide a trading strategy. What's good today might not be good tomorrow...

The cost of goods like a car are determined by how much the manufacturer and salesman wants to charge you, these are normally arbitrary numbers with a percent added to them.

If bitcoin does well you could think of it like a precious metal, you should always have demand for it and people will just offer what they want for a small profit while remaining competitive.

Do you have the wallet.aes.json or is that what you want a copy of?

I'd try requesting it from blockchain.com if you can and see what they suggest (they might be able to send a bridge that'll help with recovery too or there are versions on github).

It would be a good addition and it will encourage the habit of reading and learning, questions and answers section. Spam thread with suggestion to which the person suggesting it don't have a good clue about are rampant. Also it's annoying to write exactly what's on a link and make a thread attaching the link although it would not stand as plagiarism since a link is there it shows no real work was done.

Yeah a lot of the time websites can open badly in others' browsers so you're better off trying to quote parts that are significant or at least explaining what the person would gain by clicking the links. You shouldn't quote too much though either, if there's a sentence that isn't significant, replace it with an ellipses or add a tldr if you're anticipating discussion.

I haven't noticed people trying to link to sites without checking out the link first
4347  Economy / Scam Accusations / Re: [Scam alert]Stakedwallet Ponzi Scheme, Promising 1.5% daily. on: April 21, 2020, 06:58:05 PM
The reviews also don't look very natural, I'd normally expect to see about 70-85% 5-4*, the next highest should be a 3* and then 1* with 2 having a small number but not insignificant.



Are they not using their own coin here? So you stake their coin and get 1.5% daily, it's not actually that they're directly a scam it's that their policy on interest rates will quikcly devalue the coin (if they aren't scam).
4348  Other / Beginners & Help / Re: Try providing suggestions with summary on: April 21, 2020, 06:12:28 PM
I definitely agree with this one, I don't know if its a good idea to try to suggest it as a rule that random links explicitly aren't allowed to be used here...

A paragraph explaining why you think it's a good resource - even if it's just 100 words - is going to make people consider clicking your link if they like what you say. Also if your advertising commissions on sites go off how long a user spends on the site and use other tracking it might make your page space more competitive if people are engrossed and stay for longer...
Too many links to stuff get posted here without much in the way of explanation for what they lead to.
4349  Economy / Speculation / Re: Is Bitcoin creating panic again? on: April 21, 2020, 05:50:15 PM
The price range at $ 6,000 appears to be a strong barrier forcing the price to bounce back to $ 7000 levels once it reaches, but the persistence of not breaking $ 7600 might cause the price to bounce back below $ 6,500. So everything is possible

The majority of medium intelligence investors (ones who have been here a long time but also haven't much of a trading background) seem pessamistic this time and even though exchanges have been pushing the idea that the halving is going to happen soon and have been giving reports, I'm not sure if the mainstream media have covered it much... If any of them consider it significant and do cover it then that might attract people to look at it more and invest and cause a nice little rally up before we see a large fall down later on (probably around august if we last that long) - I don't expect us to pass $8-10k realistically but we might see some stability and a comfortable/slow decline thereafter.

4350  Economy / Economics / Re: Stimulus package drop in coinbase on: April 21, 2020, 05:41:43 PM
Its the big players setting traps, no doubt.

The $1200 stimulus package would never be sent through a crypto exchange. They will deposit it in the bank.

There will be a massive dump after the halving, due to the nature of the hype this time. 

Yeah this is more realistic, also was the $1200 not an average and did everyone even get the checks now? I thought some were waiting on that still (direct deposits have apparently gone through based on social media).

There could be a tiny rise now with a dramatic fall after the halving or even before it, I don't think the $1200 would be put into btc in its entirety either, people might throw $200 or even $10 (and given most bullish estimates put bitcoin to be worth over $100k then this still puts people in a good place to benefit from this).

I'm afraid most people are too worried about making ends meet to start thinking about investing in crypto. The only cash that could potentially move into Bitcoin right now is the one we have seen being pulled out of the stock market. I have my doubts that this money will find its way into crypto though.

5 trillion got pulled out at least, a lot of it may have already found it's way back since we're probably only about 10% down now.
But if people have had to rebalance where their funds go and a lot of stock markets offer entry to bitcoin then we may expect to see some people putting a small percent of their equity 1-5% of risky portfolio amounts into bitcoin.
4351  Economy / Speculation / Re: Currently Bitcoin has a very strong resistance? on: April 20, 2020, 07:44:30 PM
I'd put anouther resistance zone at 6800-6900, that looked like a strong zone both psychologically and for bitcoin, it may well bounce of there without going any further and I'd put that as being quite likely if we go down and don't have a dramatic drop.

If the drop is more dramatic I imagine us clearing $6000 pretty fast and pretty easily.

it also helps keep the network a tiny bit more decentralized as your node won't have a single fixed list to connect to, instead it will choose a random one and connects to.

Yes, but it's not fully decentralized, since there are prepared nodes written in bitcoin core. Right?

Let me get this straight. Node is a list of IPs that have installed bitcoin core too?

Decentralised is what it is. Distributed isn't....

Nothing on the Internet can really fully be distributed anyway since it'll have to pass through an isp or something at current.

Fully p2p solutions may come and turn the network into a distributed architecture but for now we're stuck with being decentralised and reliant on IPs and DNS server assignments from icann.

A node is something that propagates the network by storing both the mempool and other nodes ip addresses.

What do you guys think of channel probing? Is there a way to ensure someone does not find out the channel ballance?

https://arxiv.org/abs/2004.00333

Haven't checked the doc but I remember there being a difference between the amount the channel had avaliable to send to help with routing and the full balance? A lot of clients mention a push and pull figure so this would just find the avaliable to be pushed amount?

The amount was made to help nodes decide how much funds they wanted to have locked up in a contract if a party declined to comply with a htlc or lost connectivity.
4354  Other / Beginners & Help / Re: Bitcoin production cost on: April 19, 2020, 08:48:34 PM
1st problem with that study is its based on average efficiency since 2014, which is rediculous. I doubt wanyones still using an S5 these days...

You're better off looking at how many S17s or equal and high efficiency are being used (batch numbers probably get published somehwere). Or taking the average consumption of all miners from then and determining how much energy they'll need and multiplying that by the amount of mining power...

Studies are going to be useless on this as its just an estimate until you can get actual figures of units sold or pay a mining pool to tell you...
4355  Other / Beginners & Help / Re: Bitcoin production cost on: April 19, 2020, 08:25:37 PM
Look for mining calculators? I don't know what you're after?

The cost of running a miner is its power usage times the price you pay per unit. This changes based on your country...

If you're checking if it's profitible check your bill and see how much you pay per kwh...
4356  Economy / Speculation / Re: Bitcoin Price to hit $400k a prediction by an analyst *face palm* on: April 19, 2020, 07:05:01 PM


a lot of people assume every bubble will keep getting smaller in % terms. they might be surprised the next time around. don't be fooled by market cap---bitcoin's lack of circulating supply can do wonders for the price! that's what makes it so hard to to predict.

This is especially true if we collide with a recession.

If anyone with spare funds starts putting $5 or 1-5% of their net worth into bitcoin then we're going to see something weird happen.

I saw an influencer complain that they had put everything into bitcoin and randomely brought it up (and to be honest they were a real random and looked to have very little technical knowledge - the dude had a iPhone 🤣).... We saw retail pull out 5 trillion dollars and most likely put it into accounts with bad interest rates (that could soon turn negative or already have).

Warren buffet also seemed to think bitcoin was a good long for 5 years in 2018 I think but long term didn't look like the best investment (and he's probably disappointed he can't put much in it with Berkshire since market cap here is low)...
4357  Economy / Trading Discussion / Re: Bitmex Long/Short formulas for excel backtest on: April 19, 2020, 06:09:36 PM
Yeah they're converting the value into btc which youre meant to do, I was just giving a simplified outlook.

You'd take the
If you bought a coin at $100 with $150, you'd have 1.5 coins

Selling them at $150 would give you 1.5x150=$225...

So you'd make $150 profit, or 1 coin, so your 1 coin would become 2 (I think but I've been very busy today so this could make no sense) 🤣.

I think this is right and your example is with 75 contracts being bought instead of 150.
4358  Economy / Speculation / Re: Bitcoin Price to hit $400k a prediction by an analyst *face palm* on: April 19, 2020, 05:29:37 PM
If you came to me in 2016 and told me, when we were at $1k a bitcoin, that we were going to 20- would I have called you stupid? Probably.

If we continue on the last trajectory $300k is what I targeted us at I DO NOT THINK WE WILL HIT THAT but I made it an "optimistic target" and rubbed out my whiteboard...

Tbh I also think if we don't hit $150k in the next 30 months, bitcoin may be as good as dead for being a strategic investment choice... Which is good for me as it'll mean the price will become more stable and we can see more adoption.

(I really thought we were botooming out at 6k too)
4359  Other / Beginners & Help / Re: All of my bitcoin questions gathered. I need some help here... on: April 19, 2020, 03:53:08 PM
Why every 2016 blocks? Does it have to do with maths?
Because it's meant to be an average of 144 blocks a day for 14 days... I think it's a fairly reasonable sample size.

Knowing from programming, hash functions produce a fixed-length string.

SHA256 of the string "a" is: ca978112ca1bbdcafac231b39a23dc4da786eff8147c4e72b9807785afee48bb

^That output is not a number. You're saying that hash is just a number that is the subject of a compression function. Yes, target seems to be a number since you say "they want the hash to fall below the target". But... Why do you say that hash is a number?  Undecided

But it is a number? It's not denary but it's a number? Which sorts of programming have you done in the past? Have you done much with statically typed objects (c#/java/c++/c/assembly)?

Do you know binary? Is 0110 a number, can we agree it's 6?
Going back to binary, we can take the last four digits of your hex string above that forms the hash 48bb
4 = 4 (and since it's a base 16 number, we multiply it by 16^4)
8 = 8 (and since it's a base 16 number, we multiply it by 16^3)
b = 11 (1101 and since it's a base 16 number, we mulitply it by 16^2)
b = 11 (and we times it by 16^0)
I get 48bb to be 18619 (quickly input so may be wrong).

Before saying this is a stupid way to represent numbers or anything, take yourself back to any lessons you may have had discussing binary and look up what a 'nibble' is in binary... Hexadecimal is just a way to represent 4 binary digits (a nibble).

Wait... So nodes are randomly choosing other nodes? How's a node looks like? Is it a string?

Nodes are randomly selected, but if you think about the rate of computation in a machine and that you're just sending a tiny amount of data or even just pinging the node to check it has that port open (I think covering this is a bit out of scope here though).

A node, in any case on the internet is represented by it's SOCKET... In bitcoin's case, it's represented by the node's IP address plus the port.

So having bitcoin core open means that I'm having a port open too? I thought that IPs are something hidden in the bitcoin world. I thought everything is anonymous.

The anonymity is a misconception. Hosting a node can actually be anonymous if it's routed through TOR (The Onion Router), however, hosting it over the light web doesn't make it anonymous at all.

Bitcoin itself is pseudoanonymous for the time being (however this will likely be subject to change in the coming years)... You can currently see where funds have come from and are going to. You may want to look into Dash, Monero or Grin to see how they achieve transaction anonymity.
4360  Other / Beginners & Help / Re: All of my bitcoin questions gathered. I need some help here... on: April 19, 2020, 03:07:31 PM
Let's start answering you. About question 2, do you mean that if the computational power dedicated to the chain is low, the difficulty of opening a new block will also be low?
A new block ins't exactly opened it's just mined. Difficulty refreshes every 2 weeks, meaning, if for a substantial amount of time in the 2016 blocks being mined that difficulty is much lower, then after the refresh it'll become easier to mine the blocks too but the refresh will take longer since they're targeting a number harder to computationally access.

About question 3, you're writing:
Quote
They're trying to get a hash of the block to fall below a certain amount

Miners are trying to get a hash (Okay until here) to fall below a certain amount? Certain amount of what? Target? Difficulty? I'm so confused...
They want the has to fall below the target given to them. A hash is just a number that is the subject of a compression function... It takes the 1mb block and reduces it down to 256 bits and that is what is compared with the actual block.

Quote
This was originally done by chainging the nonce in the coinbase (which is an up to 20 byte number that is stroable in any transaction before it's signed)
Didn't get that...

I have another question by the way. When we download and install the bitcoin core, it downloads the blockchain right? Where exactly does it download it from since there is no bitcoin authority/database?

This is done with initial peer discovery in nodes. Generally speaking the node comes with it's own information on finding other nodes and can then find new nodes from that.

If yyour node connects to another, then that node will also send your IP address to other nodes if you allow incoming connections and once you're fully synced, you'll get connections from other nodes.
