just a couple of days ago when price had a little drop the same shitty website you are quoting today has been posting doomsday articles and were listing n-reasons why price can't go any higher and now they have made a complete U-turn and are publishing n-reasons why price is going to reach previous ATH!
do you honestly think such a site is worth quoting here? don't waste your time reading their bullshit and don't give them any traffic!
1802  Economy / Speculation / Re: Don't react to the fluctuations on: October 28, 2019, 05:39:07 PM
that is an excellent advice but the problem is that the same people who are doing the panic selling are mostly the cause of a big part of the fluctuations. specially the end of the fluctuations meaning for example when there is a big drop they sell at the bottom and push the price even lower.
if people simply put aside their fears in bitcoin market, they would see a lot less losses and we would see a lot less volatility.
1803  Economy / Speculation / Re: some people love imagining doomsday when there is any drops! on: October 28, 2019, 03:16:19 PM
I keep coming back to the days pre 2017 boom, when Jamie Dimon was the one big constant doomsday prophet, pouring scorn and ashes all over Bitcoin. Fraud? It won't end well? Can't remember the whole tirade.

And then later it emerges, JPMorgan totally went long at the dip(s), and totally FOMO'd into the market as their CEO was preparing the last rites. And then right at the top Dimon pretends to be remorseful of his comments.

So yeah, which is why I love seeing talk of capitulation and worried Tweets all over the place. It's almost like a sign telling me to get ready for some peak incoming.

oh man, the 30-40% drop that Jamie Dimon initiated in the market was so funny. he just said some bullsit in some interview and it seemed like every bitcoiner got super excited (excited for cheap prices to buy back) and started selling...
the best thing about him was the every time he kept saying he doesn't want to talk about bitcoin then continued talking about it Cheesy

now you hash it using the hash you specified for the server (it is apparently SHA256 by default)
Code:
Code:
SHA256('76a91462e907b15cbf27d5425399ebf6f0fb50ebb88f1888ac') =
6191c3b590bfcfa0475e877c302da1e323497acf3b42c08d8fa28e364edf018b

But I failed to get it using sha256. For example in PHP:
Code:
hash('sha256', '76a91462e907b15cbf27d5425399ebf6f0fb50ebb88f1888ac')
gives:
5f3f330fccb56d6b43f19b7e235f5b146ac92add3a3ab99380a39e7f7406959b

it is because you are reading "76a9..." as an ASCII (or UTF8) string not a hexadecimal string. you should convert it to its byte array representation (0x76=118, 0xa9=169,...) and then hash that.

also you shouldn't be working with hex in first place. your code must convert the address (1A1zP1....) to bytes then add the extra bytes that come from the script to it and the pass that to SHA256 and then reverse the result (bytes) and send that.
that is both faster and has less chance of having any errors like this. after all that you can convert the final result to hex if you wanted.
1805  Economy / Speculation / Re: is the market building up towards another bog FOMO? on: October 26, 2019, 04:04:51 PM
and sure enough, it took about 25 days and a final 10% drop down to $7200 to kick start the FOMO. and this was a big one too. from $7200 up to $10300 is a $3100 or 43% FOMO rise and it was nearly the same thing i was expecting. nearly because i was expecting the price to stay above $10k but instead it came to $9k level again.
i am now curious to see how this follows up in the coming days.

for now the fascinating FOMO is visible on the charts:

1806  Economy / Speculation / Re: some people love imagining doomsday when there is any drops! on: October 26, 2019, 03:31:52 PM
Expect this pump scenario will attract more FOMO's soon or some losers might be buying back their precious BTC's. Ive read yesterday about big recovery didn't expect that to happen early Grin. Unfortunate for people waiting for $6k drop few days ago but didn't happen, trully a violent drop but unexpected quick recovery.
If we see a magical pump up to the five digit, more will be attracted again pushing FOMO even more.

The thing is that people here are asking when is the right time to buy? The sign is all over, the price goes on $7400 and why are they still asking? Someone says wait for $7k or even lower. But look at what happen today, the price went on to almost $10k, and those who didn't buy are now scratching their head because they missed another golden opportunity.

you pointed out something very interesting that i have been thinking about for a very long time now. i believe that the main reason why price has falls like what it had recently is exactly this uncertainty that people have about whether to buy bitcoin or could they get a better deal. so they stay out waiting instead of buying. so it becomes easier for the price to be manipulated and drop even though the real buy support is a lot stronger than it shows.
it becomes more apparent when the price jumps back up since it is showing the same people are jumping back in (FOMO).

Not worth talking the site down since it's only been online for roughly a week now.

sorry, i didn't mean to belittle your efforts, i was just criticising the site. as long as you work on the "ranking" mechanism that you use and don't rank coins based on their market capitalization, it will be a lot better than the alternative.
1808  Bitcoin / Development & Technical Discussion / Re: Is encrypted mnemonic technically possible? on: October 26, 2019, 02:59:15 PM
Another thought would be to split your seed with SSSS.

although it could work but Shamir's Secret Sharing (3 S not 4) is designed for when you want to "share" a secret between multiple people so it is more suitable for cases when more than one person is involved. not for the case where 1 person wants to encrypt and store 1 secret (mnemonic) in a safe way.
1809  Bitcoin / Electrum / Re: Electrumx protocol on: October 26, 2019, 02:41:06 PM
you have an address that you want to check, each address (based on its type) corresponds to a certain type of script in this example the address starting with 1 is a P2PKH address so the script of it is DUP HASH160 <hash> EQUALVERIFY CHECKSIG

so you start from the address:
1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa
base58decodecheck to get the hash (after removing the version byte)
62e907b15cbf27d5425399ebf6f0fb50ebb88f18
build the script from the hash
76a91462e907b15cbf27d5425399ebf6f0fb50ebb88f1888ac

now you hash it using the hash you specified for the server (it is apparently SHA256 by default)
Code:
SHA256('76a91462e907b15cbf27d5425399ebf6f0fb50ebb88f1888ac') =
6191c3b590bfcfa0475e877c302da1e323497acf3b42c08d8fa28e364edf018b
but the document says that for sending this hash digest to the server you must reverse its endianness so you simply reverse your bytes that you get from the hash result then send it to the server. the reverse of the hash is:
Code:
8b01df4e368ea28f8dc0423bcf7a4923e3a12d307c875e47a0cfbf90b5c39161
(note the start of previous code block with the end of this last code block: 0x61, 0x91,... turns into ...., 0x91, 0x61
1810  Bitcoin / Bitcoin Discussion / Re: G7 report regarding Bitcoin and all cryptocurrencies. on: October 26, 2019, 02:28:58 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!
It is very logical that Stable coins are Bitcoin dependent. But every year, Stable coins gain more and more popularity and even go beyond the cryptocurrency market.

i have not ever seen any of these stable coins go beyond the cryptocurrency market, could you show me an example of one in real world?
the only popularity that i have seen them gain was from traders and that is because of the extreme volatility of the altcoin market and the fact that they want to use an escape route that is not changing price with bitcoin. and since over the past 2 years ever since bitcoin drops altcoins drop the best choice has been stable coins otherwise they have no purpose.
1811  Bitcoin / Bitcoin Discussion / Re: Crypto Mega Breakout - 56 billion dollars in a few hours !! on: October 26, 2019, 02:19:52 PM
the only problem is that it is not actual "dollars" that are going in the market. it is only market capitalization which you are looking at and that is simply showing the ridiculously huge amount of altcoin supply that is currently in the entire market and none of them went up by people buying them with "dollar". the only thing that happened was that bitcoin went up so if anything you should only report bitcoin's market cap (although that still wouldn't make any sense) and that would be about 20 billion rise.
1812  Bitcoin / Bitcoin Discussion / Re: China's President Xi Jinping VS Bitcoin on: October 25, 2019, 07:15:15 PM
it seems like yet another vague statement from a government and the news sites that are going ape shit over it, the worst part is that the statement doesn't seem to be exactly about bitcoin if at all. it is talking about the "blockchain technology".
in the end the governments want to keep and increase their control, that means trying to "compete" with something they couldn't fight (ie. bitcoin) which requires adopting its technology and staring their futile attempt.
1813  Bitcoin / Bitcoin Discussion / Re: Private Key by 256 coin flips on: October 25, 2019, 06:50:29 PM
meddling with entropy and using a physical source (anything except what your computer generates) should be considered an advanced topic which regular users should not try to perform without first educating themselves on how it is done correctly and are aware of possible biases and other issues that might be involved.
I'm not sure about that, it's well known that computer generated entropy is globally less safe than physical ones, where have you seen the opposite?

first of all my point is that people should never use a method that they may not understand the risk of. for instance using a coin may sound safe but what if the user who was using this method used a biased coin? or messed up entering the results and put more 1s than he should have? or what if he used a bad code that converted things wrong?....

secondly when you say "less safe" you should know that it does not mean "not safe". for example there has been millions of bitcoin keys used so far, i bet 99% of them are produced by a computer and an RNG. we only have rare cases where a shitty tool like blockchain.info wallet, etc led to losses due to bad RNG. the decent tools such as bitcoin core, electrum, and lots of others have never had such problems!
1814  Other / Beginners & Help / Re: How to import 2-of-3 multi-sig keys to Bitcoin Core wallet? on: October 25, 2019, 06:23:44 PM
if you are sure that you are entering the same public keys and required signatures (2 of 3) in both places and also are generating the same type of multisignature address then the only reason why the resulting addresses could be different is if one of the tools is "sorting" the given public keys and the other one doesn't so the hash of the sorted keys is a different one and as a result you get a different address. (read my edit below about sorting if you are using bitcoin core)

try changing the order in the tool (coinb.in) that doesn't sort them to see this.
example of this case with 3 random public keys that i generated using bitaddress.org for this purpose only, and using coinb.in site for the multi sig addresses:
public keys with orders:
Code:
038B66DD2C771B58271C995D8ECBF06EE60DEF61BA4B843F4AA9731DD724FDA87C
034B966F86E8DE46A58C456D0695C9B2ABB2BD7F35F0BC62F0DE45A816BD667413
02F87E983C5A1033D2EA39B5985360947A526DDB495417D1FD121B66BCA859220E
address:
Code:
3Eoq2jmc66Qv4ziRoUKkHAFkwHncNhj7mP

same pubkeys with different order (changed place of 1 and 3)
Code:
02F87E983C5A1033D2EA39B5985360947A526DDB495417D1FD121B66BCA859220E
034B966F86E8DE46A58C456D0695C9B2ABB2BD7F35F0BC62F0DE45A816BD667413
038B66DD2C771B58271C995D8ECBF06EE60DEF61BA4B843F4AA9731DD724FDA87C
address:
Code:
3AzS4Wk6xQ2tmKw6pKP4jwwa3eyw7E8tbC

edit:
i checked my unseynced bitcoin core version and it seems like i was wrong, it also doesn't sort anything so you must have entered the keys wrong. the equivalent of the above exampels are the following commands which did return the same exact address:
Code:
addmultisigaddress 2 '["038B66DD2C771B58271C995D8ECBF06EE60DEF61BA4B843F4AA9731DD724FDA87C", "034B966F86E8DE46A58C456D0695C9B2ABB2BD7F35F0BC62F0DE45A816BD667413", "02F87E983C5A1033D2EA39B5985360947A526DDB495417D1FD121B66BCA859220E"]'
Code:
addmultisigaddress 2 '["02F87E983C5A1033D2EA39B5985360947A526DDB495417D1FD121B66BCA859220E", "034B966F86E8DE46A58C456D0695C9B2ABB2BD7F35F0BC62F0DE45A816BD667413", "038B66DD2C771B58271C995D8ECBF06EE60DEF61BA4B843F4AA9731DD724FDA87C"]'

that we would head down to 4k after they do saw that the price plummets on 7k level and now we do see almost 9k price in a short time.

that's normal for every drop that we have ever had. there are some people (newbie day trader) who sell their coins too late and in order to be able to buy back and not lose money they would need a lower price. since that's not happening they start an online campaign expressing their wishes as speculation!

14% up in no time,so the recent drop was pure manipulation and targeted against the people who thinks that way of continuous drop in the near future.I didn't knew or read any news for the price drop and the rise as well in the current week.Lets hope for the best from now and will hang on at the price level of $10,000 until the next halve.

i wouldn't open up the champagne yet. a real "recovery" and the end of manipulation is when price has gone back to realistic values above $10k again. so long as it is in this range it is  still manipulated. the only thing the past 48 hours proved is that $8k is pretty strong as a support.
1816  Economy / Speculation / Re: The Price of BTC on: October 25, 2019, 05:57:52 PM
your entire argument is flawed because security is not something that has levels (at least not in the way you are describing it). something is either secure or it is not. in case of bitcoin, it is either expensive enough to attack bitcoin which makes it secure or it is not which makes it insecure.

not to mention that in the end the only deciding factor is the demand for bitcoin. it can continue to have the same hashrate and as long as the demand continues rising the price will too. and vice versa, meaning if demand decreased, even if the hashrate remains the same, price will fall.
1817  Economy / Speculation / some people love imagining doomsday when there is any drops! on: October 25, 2019, 05:48:41 PM
over the past 2 days that we saw a small 9% drop i have seen all kinds of so called "speculation" where people are seeing all kinds of doomsday scenarios. in some cases it is wonderful how their imaginations work. from simple whales manipulating to the good old China bans bitcoin has been the heated topics over the past 48 hours!

what happened? price started a tiny rise then the FOMO kicked in pushing the price back up. guess who was FOMOing? Wink
1818  Economy / Speculation / Re: Bitcoin Dump on: October 24, 2019, 04:31:33 PM
Here is the chart of bitcoin. Check yourself. Yesterday it was 8 000 and today around 7500[/b]

a one time 6-7% drop doesn't mean miners are panic selling just because you might have heard some rumor somewhere on the internet!

Now regarding Tether (In your opinion it is a shady altcoin) Dude.. Do you know what is Tether ?  I guess no ! It is a stable token and the price is always equal to 1 USD. A lot of traders are using it for arbitrage trading and for many other reasons. It is ranked #4 on coinmarketcap.

Educate yourself a little bit, before posting something. [/b]
well you can deny it all you want, it is centralized, the company behind it has always made false claims without ever providing any kind of proof that their tokens are backed with real fiat. they have never been properly audited and they are always evasive about it with shady behaviour and they keep printing more of it without control!

are a lot of exchanges using it? yes
are a lot of traders using it? yes
does it have a gigantic volume? yes
has its price always been equal to $1? yes, there were times it has dumped lower.
does any of this reduce from its shadiness or risk? absolutely not.
1819  Economy / Speculation / Re: Bitcoin Dump on: October 24, 2019, 02:34:54 PM
Chinese authorities are planing to launch some more crypto restrictions, that will affect the big Chinese mining farms.
you don't have to worry about a business that has been inside China for many years. they know how to handle their own government and their laws!

Quote
yesterday some very big sell orders appeared on all major exchanges.
in conclusion after 24 hours price hasn't move due to these "big sell orders"!

Quote
and bought some tethers.
you made a huge mistake. if you want to go out, then convert back to real fiat not a centralized shady altcoin!
