2101  Economy / Trading Discussion / Re: Prices rises - Tx fees stay low? on: August 12, 2021, 08:33:02 PM
You're probably too paranoid. I'm assuming we've just lost the first wave of retail - they'll probably come back once the second wave and original holders start bumping the price up again. There are people a lot of people dcaing and buying the non-new-highs and a lot of funds on exchanges.

There's a chance we lose more people than March 2020 since we've stayed down a lot longer though. But saying that, we've done 10x in a year - literally... If you were here a year ago then you've probably done well even if you held your btc since the top in 2017...
2102  Economy / Service Discussion / Re: Is there an app where I can set an alert for a coin every +/-%#? on: August 12, 2021, 02:06:28 AM
Not sure on anything else but I've just found the option on tradingview, you go to select the asset > alert > change crossing in the drop down menu to "Move Up %" or "Move Down %" > set value and bar limit > change frequency to every time or something else (like once a minute).

It might depend on how they have invested though. If the people answering the serveys are confident in their investments then they might be up and have pulled their original investment out (then it wouldn't really be a gamble).

Lending to invest is quite a bad idea but if you've leveraged different types of investments then it's probably fine - especially at low interest (you can get mortgages about the rate of inflation now - and if the worst happens you can often get planning permission to split houses up and rent out individual flats - but it's likely not worth that hassle).
2104  Economy / Trading Discussion / Re: Anyone Know Tools Trading Price % Movement for 30 second - 1 minutes time frame? on: August 11, 2021, 04:33:08 PM
I was looking for some tools to check the price movement of cryptocurrency give you some information about movement price increase/down for the last 30 second/1 minute time frame.

Tradingview does by second data normally if it's available but you have to pay for premium to get it - they normally have a sale at the end of November though.

They have a compare option too but I'm not sure how far it goes. You might be able to look around for some api implementations you can use to build up a chart of you've got any programming experience also.
2105  Bitcoin / Bitcoin Discussion / Re: How can you combat market gloom? on: August 11, 2021, 04:24:12 PM
I just ignore stuff when it goes downhill, especially if you can find a reason for it.

If it's dramatic, find something to watch for a few hours or enter trades you can forget about - I normally forget about a lot of mine anyway if stop losses are set or it seems quite we well run project (although that's normally shares I trade long term so they have a lower chance of dropping far)...
2106  Economy / Economics / Re: Bank of Ghana to pilot CBDC with German securities printing firm G+D on: August 11, 2021, 03:54:13 PM
CBDCs are truly digital currencies, but they are still as centralized as Fiats, all CBDCs will be subjected to governmental (central) control, this will make CBDC to be inflationary currencies, subjected to devaluation, resulting to price depreciation. In Africa, Ghana is working towards digital currency pilot, likewise Nigeria, but nothing special about CBDCs than been a modified form of Fiat, they are pegged with Fiats.

They are probably also likely going to be at least identifiable by the government for who's sending money to who also which might be a problem - especially if they sell this data on.

I think they'd also add a level of anonymisation to banks and themselves so they can keep inflating the currency. There are additional problems with inflation in that it might not keep a currency rising in value to the extent you'd need for it to be competitive - you might need inflation in some cases of the major powers have it as your currency will be expected to track them by the market.
2107  Bitcoin / Electrum / Re: electrum on flathub? on: August 11, 2021, 10:48:15 AM
Is flathub not compatible with github directly, the links on that flathub site seem to suggest it is.

I can get this link from clicking on the publisher https://github.com/flathub/org.electrum.electrum/community - you can use that to see who's added commits to it.

That is NOT electrum's official github though. Electrum's official github is: https://github.com/spesmilo/electrum

There is a chance, unless Thomas V's signature verifies, the other version is a scam.
2108  Economy / Trading Discussion / Re: Volatility Indicator on: August 10, 2021, 07:54:08 PM
I'm sure I heard someone talk about bollinger bands or something for doing this. If the price is outside of the band, the asset is volatile.


Bollinger band don't look perfect for this because it is not an indicator to rely on for proper direction. Some times working with it you can be correct and other time it will fall. Also you can hardly predict when the volatility of the market has ended but you keep being in the market, this is risky to use but if it can be combined with others, then you can manage on it , Bollinger is a lagging type of indicator.

Yeah you wouldn't rely on one thing at once though when it comes to indicators. Some are a bit more accurate but they're best being put together.

And yes I know the stratefy with bollinger bands is said to be to buy a breakout and it's one of the reasons I didn't mention that part of the strategy for the number of times it likely fails - especially if too many people are looking at that same indicator. Breaking out and then going back inside the indicator probably means volatility went up though - but still less reliable than volume.
2109  Bitcoin / Development & Technical Discussion / Re: Can bitcoin 0.1.0 code still interact with the blockchain? on: August 10, 2021, 04:23:06 PM
I really wonder, though.

If we install the v0.1.0 in two computers and let them connect through the GetMyExternalIP, assuming “72.233.89.199:80” or any other IP they decide works, will they start mining the chain from the genesis block? Is there anything that'd prevent them from having their own chain since they'd not be interacted with the current nodes even if they connected somehow?

Well yes, but you might want to look into testnet instead or as well as that - I think the download is quite a bit smaller too but that's a public chain.

I think there's a version around 8.8 or 12 that is compatible with the most recent blockchain
You're talking about Bitcoin-qt 0.8.0
I feel like there was one immediately after 0.8.0 that also had a major update - not sure how critical the memory leaks were of 0.8.5

I also think the original (0.1.0) version used a public key for identifying who funds were being sent to (making it much bigger than just using a hash of the key)

To be specific, it's uncompressed public key which barely used these days.

As well as the ripemd160 hash that also gets used which probably means the address is quite a lot smaller than an uncompressed public key.
I think there was a pay to IP option at some point too that got removed (it had quite a lot of problems associated with it - especially since communcations weren't encrypted).
2110  Bitcoin / Bitcoin Discussion / Re: Blockchain is the catalyst of the fourth industrial revolution on: August 10, 2021, 03:59:08 PM
that's why Blockchain technology is the greatest invention in the fight against Bank corruption/Money printing corruption.

Banks and similar industries will still be able to make use of the blockchain and in some cases have already done - a blockchain produced for a decentralised ledger of the clear web and deep web will contain a lot of information from banks and other services like health and legal.



I think the fourth industrial revolution was more started by countries having a vastly different level of wealth. Even looking at Europe, southern/eastern europe manufacturs goods by hand or with more traditional methods, while the north/west of europe (which is more expensive for everything) prints a lot of the stuff it manufacturs. If given the option, are you going to hire someone in a call centre for $300/month or $2000/month if they can perform the same job?
There's also the consideration of how you can have a video call connected to most places in the world and not experience any major lag (half a second/a noticeable problem would be considered long).
2111  Economy / Exchanges / Re: Where is the best platform to trade futures and contracts with high leverage? on: August 10, 2021, 12:23:30 PM
Are bybit not high leverage? You could try them or maybe kucoin.

I've been using primexbt for a while (when I don't want to use binance) and it seems alright but is limited to just 100x and fewer coins.
2112  Bitcoin / Bitcoin Discussion / Re: Satoshi Nakamoto should have created Litecoin with the Bitcoin name on: August 10, 2021, 11:58:21 AM
The issue with this is that the community decides what they want to support and they mainly have users who want the most secure chain or the most innovative (and most of the major alt coins are neither of those). Bitcoin's security is much better than almost every other cryptocurrency because of the level of exposure it gets as well as the hashrate (quite a bit of bitcoin news makes its way into mainstream news - or has done in the past wgne significant events occurred).

You selecting one out of hundreds makes no sense. Besides if LTC were any better than bitcoin then it would have been actually used as a currency while it isn't.

It is at least accepted in a lot of places bitcoin is when buying things (as well as other coins like bcash, monero and ethereum).

Litecoin is nearly identical to Bitcoin"

It is essentially the same thing though too... Litecoin seems to not have much work being done on it though with it being left idle for over a year on github.
2113  Other / Beginners & Help / Re: I am trained in software engineering but don't know bitcoin on: August 10, 2021, 01:52:16 AM
Do you know what you want to learn, the topic itself is quite big, also how do you learn best?

I started learning about bitcoin by getting hold of some and using it to transfer funds to myself and a few friends for example.

If you're not too code oriented, you might want to look into hashing algorithms, digital signatures (bitcoin uses elliptic curve but you could start at rsa to get used to that type of encryption) and then move on to looking at blockchain. There's quite a few good Wikipedia pages on these where you should be able to learn everything you need to know - or find it from their external links at the bottom.

Finally, if you are quite experienced in programming (you didn't say how long you spent learning/practicing it) you could look at either passing the bitcoin source code through an interpreter (a type of code translator that takes an application line by line and runs it) or looking at constructing your own version of certain parts of the software (as much as you want) .
2114  Bitcoin / Development & Technical Discussion / Re: Can bitcoin 0.1.0 code still interact with the blockchain? on: August 10, 2021, 01:36:31 AM
No there have been too many changes for the 0.1.0 version to be compatible with the current bitcoin blockchain.

Running anything other than the latest version is kind of asking for getting vulnerabilities, I think there was a version a few years ago that had a few critical vulnerabilities that had to be patched (partly to do with DDoS and something else)...

I think there's a version around 8.8 or 12 that is compatible with the most recent blockchain, however, doesn't benefit from the lower transaction fees the newer software has that makes it able to segregate signatures away from the transaction making it quite a bit smaller. I also think the original (0.1.0) version used a public key for identifying who funds were being sent to (making it much bigger than just using a hash of the key)

There have also been releases with the more recent versions to increase initial block download time and client synchronisation (since it's around 350GB now I think).
2115  Bitcoin / Electrum / Re: Electrum change addresses in Preferences on: August 10, 2021, 12:43:09 AM

  • I remember that the wallet I opened contains imported private keys. That must surely be the reason why the app unticked the option for any change to be sent to change addresses.


I think it's likely that one because I saw your option for using multiple change addresses was grayed out on your preferences menu while it's quite functional on mine.
2116  Bitcoin / Electrum / Re: Electrum change addresses in Preferences on: August 09, 2021, 08:51:25 PM
It was selected automatically on mine - but I'm using the standalone version. It's a fresh install of everything because I was speeding up my computers - nothing copied across.
2117  Bitcoin / Bitcoin Discussion / Re: Huge financial firm NCR to acquire BTC ATM operator and POS firm LibertyX on: August 09, 2021, 07:24:59 PM
I wonder if these bitcoin ATMs are profitable or not and how many people a day use these bitcoin ATMs and it is not necessary for governments to approve the installation of these bitcoin ATMs? can someone answer these questions? in my country the central bank controls all ATMs and it is not possible to install an ATM without the approval and license of the central bank


If they're just in a shop and no ones paying rent on them then they're probably quite profitible (if the main costs are electricity and holding cash/crypto).

In the UK private individuals/companies can own atms. Debit cards are controlled by government regulations as they set limits on how much you can withdraw at an ATM, pay via contactless and pay to use the atm (you can't be charged now).

Most large supermarkets in Europe have exchange machines in them too to convert currencies (often at least the Euro to the local currency) and I doubt they need a license.

from what I see it seems more advantageous to withdraw money from cex.io to the bank as the money arrives in an instant than using these bitcoins ATM

Yeah but there's probably a use for them in some places. I think bank transfers in some countries are still quite slow - if you don't already have money in your account which might be the case.

It's 8% at the local ATMs
There are some that are farther away that were less, but for a test to throw $50 in a machine it was not worth the gas & time.

I think 8% is alright for what it is. The fee suggestions do seem a bit high then but that might just be to save funds as they'll need less customer support if there's a lower chance of transactions not being confirmed.
2118  Bitcoin / Development & Technical Discussion / Re: How to verify the results of glassnode? on: August 09, 2021, 06:08:19 PM
Are you experienced in programming, how is the best way you'd want to enter a query like that - could you do it in python or would you prefer SQL?

It's highly likely that a list of addresses will not fit in a single SQL database.

That'd just be how the command is input and interpreted, a lot of database management systems built into a programming language (for example) will just iterate over the raw data if asked to count it (which is what we would expect to be the most efficient here - it could dump addresses and their balance in a file but that might not be necessary).
2119  Bitcoin / Development & Technical Discussion / Re: How to verify the results of glassnode? on: August 09, 2021, 05:28:21 PM
Are you experienced in programming, how is the best way you'd want to enter a query like that - could you do it in python or would you prefer SQL?

I have found a thread discussing querying the data on the blockchain - https://bitcoin.stackexchange.com/questions/61252/how-to-learn-to-query-the-block-chain

There are also a few implementations of python chain parsers you might want to look at, for example - https://github.com/alecalve/python-bitcoin-blockchain-parser (but I haven't tested this).

If you had the time or money, you could also commission someone else to do this - you could also look at APIs that might be available from block explorers too.

I couldn't find commands for querying this in bitcoin core itself looking at the help menu but that might not mean there isn't one, it's just not well documented on the console start screen.
2120  Bitcoin / Bitcoin Discussion / Re: Huge financial firm NCR to acquire BTC ATM operator and POS firm LibertyX on: August 09, 2021, 05:07:26 PM
... expensive ...
Did you manage to work out how much the markup was? I feel that anything around 2.5-10% might be considered reasonable, especially if they'll hold the rate for a few hours.

And if you're not paying for the fee (directly) then it might be best them sending one that's a bit high for current market conditions - especially since the fees were really high a few months ago.

Process was start buy on app, get price that is fixed for a couple of hours, go to machine, put in cash, get BTC.
Is it easy to cancel a trade? If there's a crash or a rise is there some protection on that (for both ends) or do you think they'll just hold the rate where it was and assume any losses that come from that?

But it's good that NCR is not participating in bitcoin network directly but they are into facilitation business. So it's a little less risky for the market to be honest!

Most companies seem to be attempting to start small if at all in crypto so it's probably a good place for them to start too - it'll give them their own insights and data too on the market.
