1821  Bitcoin / Project Development / Re: Crypto prices, trades & volume in realtime excluding fake volume on: October 23, 2019, 03:48:37 PM
so you are excluding the "obvious" fake volume not fake volume in general. the exchanges can still continue producing fake volume and if someday your website (or the method in general) became popular they can easily mask it.

in addition to that you are putting too much efford and focus in something that doesn't really matter for sites such as yours that list coins. you are still making the same mistake as coinmarketcap.com and rank coins based on their market capitalization which is a completely meaningless and wrong approach.
not to mention that your site lacks the option to list prices against bitcoin whcih in my opinion is the only thing that matters, you only have USD option.

you say "hackers have already abandoned this method" as if there is only one group who decides which method should be used and which shouldn't!

when a hacking method is invented and it can successfully "hack" people, and then it becomes known, everyone else would also start doing it. soon enough you see a lot of the same malware being created and spread by lots of malicious people.
in other words calling the advice "stale" doesn't make any sense since the method is still very much in use.
1823  Economy / Speculation / Re: Bitcoin is going down...now at $7,654.85 on: October 23, 2019, 03:24:45 PM
although the drop is not that surprising but i don't see any reason why anybody could have anticipated it. of course you could have given it a little chance as price wasn't going up and attempts at breaking the resistance was failing but also at the same time attempts at breaking the buy support was also failing and it was strong considering it was tested a couple of times withoug breaking and there was no reason for the drop to happen at all.
1824  Bitcoin / Bitcoin Discussion / Re: G7 report regarding Bitcoin and all cryptocurrencies. on: October 23, 2019, 02:59:31 PM
Stablecoins have usecases only while crypto coins is alive in my opinion

that is somewhat true because you should first consider day trading and remaining inside exchanges as "use case" before you can make that claim and also you should clarify that "stable coin" refers to the cryptocurrencies such as tether not libra.
remember than this report mainly means libra when it says "stable coin" which is different. it is useless with or without cryptocurrencies!
1825  Bitcoin / Bitcoin Discussion / Re: Statement against people who say Bitcoin is a Scam on: October 23, 2019, 02:48:44 PM
i have never seen anybody say that genuinly. people who say it are either FUDsters trying to manipulate the minds of newbies for their own benefits or are newbies who are repeating something they have heard by the brainwashers.
in some cases when they say it they are targeting the altcoins which makes sense as a lot of them are indeed scams created for fast money grabs from the newbies who don't know much.
1826  Bitcoin / Bitcoin Discussion / Re: Early investors and adopters backing out or losing their hope is a warning sign. on: October 20, 2019, 05:43:57 PM
the mistake here is that you have absolutely no way of knowing what the "early adopters" are doing. whether they are losing hope, leaving or staying,... is not something they would ever publicly advertise for others to know. for example if someone "backed out" and sold his coins and left they won't come tell us about it!!!
and more importantly if you saw someone who is telling you, you can be almost sure they have other agenda in mind that are doing that.
1827  Other / Beginners & Help / Re: How to tell if a transaction is legit? on: October 20, 2019, 05:12:57 PM
So am I right to say that after miners mine a block, then they select a group of unconfirmed transactions from the pool and add it into the block?

they do the selection before they mine the block, you can't mine something that is not yet constructed.

so first the node receives transactions and verifies them. then the miner chooses transactions and adds them to their block. then based on those transactions they build something called a "merkle root" which is a final hash calculated from all the transactions inside the block (it is build like a tree, hash each 2 and add the result to next branch then hash the 2 results,... until you reach 1). that way it ensures the transactions in the block can not be changed. this merkle root is included in the header which is then hashed repeatedly by changing the nonce each time until the miner can find the hash that they are looking for.
1828  Bitcoin / Bitcoin Discussion / Re: I just turned 40 today and want to be part in BTC Community (Beginner) on: October 20, 2019, 04:42:49 PM
since you are new to this world then my advice would be to stay away from altcoins for now. just stick to bitcoin, learn how it works, which wallet suites you best, how to secure your coins, learn the basic concepts such as private keys/cold storage/blockchain/confirmation,... you'll have a lot to learn and it is mandatory to know these things. (you can start from bitcoin.org)
this way you can start the right way and then you can make up your own decision whether to even touch altcoins or not.
1829  Other / Beginners & Help / Re: How to tell if a transaction is legit? on: October 20, 2019, 04:27:31 PM
- When I make a transaction, this transaction is added to a pool of unconfirmed transactions
- this pool of unconfirmed transactions forms a block and miners will solve a mathematical problem as verification

- "pool" is not one location on the internet that transactions go to. it is the memory (their RAM) of every single node that runs a bitcoin full node client.
- the "pool" doesn't turn into a block! the pool only contains transactions that are not yet in a block. then miners choose transactions from this pool to place in a block they mine.

Quote
However, how do they know if my transaction is valid? What if I have 1 BTC but decide to send 2 BTC, how does the solving of mathematical problem verify that I do not have 2 BTC? What if I just purchased 5 BTC from Coinbase using fiat, how will anyone know that I have 5 BTC?
mining has nothing to do with transaction verification. mining is just hashing the block header to find a result that is smaller than the block target.
the verification happens separately. and it is simply done by looking at the blockchain. when you receive 1 BTC you are receiving it in a transaction, that tx is recorded on the blockchain. when you spend coins, you are spending that tx and the amount of it is also on the blockchain. so when nodes see your spending tx they check to first see if it has not been spent before, then they check if you are spending an amount less than or equal to the amount of that input. if you spent more it will be considered invalid and rejected. if you send a tx that is already spent it will be considered invalid and rejected.
1830  Bitcoin / Bitcoin Discussion / Re: Stable Coins are a Threat for Bitcoin? on: October 20, 2019, 04:13:24 PM
they are all centralized and highly risky, there is no threat in that for a decentralized bitcoin like bitcoin. specially from dozens of them that keep popping up like mushrooms these days.
the only thing that could only cause a short term drama and that only in price of bitcoin is tether and that is only because it is oldest and biggest otherwise they have nothing to do with bitcoin.
1831  Bitcoin / Development & Technical Discussion / Re: How do nodes connect to each other? on: October 20, 2019, 03:51:51 PM
Why using both v4 and v6?

it is a networking thing, not everyone has adopted IPV6 yet (in fact according to google only 26% of the world is using it right now) but it is recommended to move to V6 because of V4 exhaustion, so if you have it you must advertise that but to let those who don't have it you must also advertise V4.
i believe what bitcoin does is that it mapps all IP addresses to V6 so it can show you both at the same time.
1832  Bitcoin / Development & Technical Discussion / Re: How do nodes connect to each other? on: October 20, 2019, 03:14:55 PM
I have two clients on the same wifi network and they connect to each other via IPv4 and IPv6 how the hell is that possible?

if they are actually connected over the internet (not through any other way) then it is not surprising really. every client has an IP address that it broadcasts to others as it connects to any other node through a version message. then others send its IP to other nodes and that way it propagates. so your other client eventually finds out about that IP, most likely right away if both are connected to same node(s) and attempts connecting to that IP.

1834  Other / Beginners & Help / Re: Cryptocurrency Report for Beginners to Serious Traders on: October 17, 2019, 04:03:37 PM
So far, coingecko has not provided a classification of currencies on the basis of technology as many cryptos are considered copy/paste verisons, so it is shameful to be classified first because the financial aspects are good.

I think that classification based on technology or any other fundamental is a opinion based. This is not interesting for a report, imo.

actually i believe that classification based on technology is not just good but it makes things easier. for starters you can easily eliminate a great percentage of altcoins since they are poor copycats then you are suddenly left with a much smaller number of coins (for example 20 instead of something like 3000).
then it is a simple matter of checking how different those coins are from each other and whether they have any kind of innovation in their technology.
1835  Economy / Speculation / Re: "Bitcoin: Bearish Mood Strongest Since February" on: October 17, 2019, 03:42:06 PM
charts do not back up what you are claiming in your title.
there is fear and some bearish mood but it is not even close to the fear and bearish mood that existed in the beginning of this year. you are basically claiming that right now that we are after a 200% rise and the big reversal after the ATL and everything has changed we are still in a situation like in February when the price was still at the bottom and the reversal had not happened yet and we were after a 85% drop!

i literary see nothing in common in the two time frames!
1836  Bitcoin / Bitcoin Discussion / Re: Why Bitcoin is in Short Term Accumulation Stage before Halving FOMO on: October 17, 2019, 03:24:27 PM
halving is too far away, so how can bitcoin "currently" be in a "short term" accumulation before the halving FOMO?

besides, as i have said before bitcoin right now is getting ready for an immediate FOMO the only thing needed is repetition of a couple of months ago when price went above the resistance of that time at $4k to break out and we start seeing yet another big FOMO this year.
if that happens, we can easily see prices above $15k and closer to $20k in a very short time far before halving.
1837  Bitcoin / Development & Technical Discussion / Re: Is possible get public key from signature? on: October 17, 2019, 03:11:46 PM
This procedure give me:
r= 205d2cb95368167baa75ff86a36827a732ac1ab4ea5c9f53ebebf1c2ae738cc9
s=21009cbec84f5941c7a85a76ef4c617b66a0c52e66e9ec5e8374480521d57a588e
is easy to verify that its are substring of signature hex string

you are forgetting to move your pointer forward after you read the integer lengths after "int intLen = bytesBegin[ptr];" and "intLen = bytesBegin[ptr];" lines. the result is that your r and s values have an extra byte in then (20 and 21 respectively).
1838  Bitcoin / Bitcoin Discussion / Re: Using Locktime for inheritance planning, backups or gifts on: October 17, 2019, 02:51:28 PM
Hey, do you have some block height to date converter estimator thingie? (or the other way around, date to block height)

the only way to do that is by using an estimation and you won't need a tool for that you can use a simple calculator and assume there are fixed 144 blocks per day (1 block/10 min * 6 * 24) and then multiply that by number of days you want.
1839  Other / Beginners & Help / Re: Let's stand against Bounty Scammer. on: October 15, 2019, 03:50:32 PM
well it is like wanting to stand against greed, not just your own greediness but the greed of other people! you can't really tell people to stop wanting to make money, they are new and greedy and want to believe in the promises of "huge return" and the "next bitcoin" crap they feed them and join their token scam fundraising shenanigan! and they won't change.

the solution is easy too in my opinion. only get paid in bitcoin so that you can first of all guarantee you are receiving something valuable not something worthless (ie the token) and secondly you make sure the owners have to spend money (which they should do if they are serious and not jus scamming) instead of paying with the token that didn't cost them anything to create. and finally using bitcoin gives them the opportunity to ask for escrow!
do this and 99% of scammers run away in the other direction.
1840  Bitcoin / Bitcoin Discussion / Re: "Cryptopia: Bitcoin, Blockchains and the Future of the Internet" on: October 15, 2019, 03:33:30 PM
i could have gotten excited if the list of those appearing in the video didn't contain Roger Ver and Vitalik Buterin. i really don't think these people understand or even care what bitcoin is all about. they have proven that they only care about their own power in the scene and the money they can make from the "hype".

I wouldn't want to see them either, but the author is probably an outsider to crypto, so we can't expect from him to know all the nuances of crypto community. Let's just hope that he won't give any exposure to Craig Wright.

oh shit, i didn't even remember Craig Wright! more like out of sight, out of mind as it seems like these days the drama with this scammer has ended and he is now a footnote in the history of bitcoin as an idiot who tried to fool others but failed Tongue

i should also have said that this video has Andreas Antonopoulos which should automatically increase the quality of the final product by a lot.
