why call it pump, and why expect a big sink! i don't get it. the biggest FUD of this year was the BU split FUD that could only cause a dip down to $9XX range and momentarily testing the $8XX range. and that didn't even last long! and that was the biggest FUD, what else do you think can be that big to cause such a dip, specially if price goes higher.

click on the link that i gave here, then scroll down a bit, under the chart there is a link on the right side saying export, that gives you the raw data in CSV or XLSX format and inside that there are two columns called Time and USD. that is why my total number which was calculated with that data is in USD.

i think you misunderstood me a bit. if it was hackable this way first ones to be hacked would have been the big exchanges hot wallets and then services which contain 100s+ bitcoins

one additional thing about address reuse you need to know is that you are also putting your public key out there.
here is the pubKey belonging to the address you put in your profile:
and this is directly derived from your private key after usage of ECDSA. there is no SHA256, HASH160 performed on it like your bitcoin address starting with 1.
while this is still perfectly safe and there is nothing to worry about, but in the future there may be some weakness found in ECDSA and used to find private key from that pubKey you already revealed by spending bitcoin from that key. this is a small chance but still something to consider

to my knowledge no, and it is highly unlikely because as i said these are rare cases.

Things are still perfectly fine. there is always a chance of unknown bugs being found but the chances are small. and the chances of those bugs being serious are much smaller. and Electrum has been being using for many years by many users. and most of these bugs show themselves through usage.

0.) Spammers stop spamming the network with spam transactions, or they run out of money. also miners stop putting their own transactions in the blocks they mine to waste space which would otherwise be free.

i have no idea what coin.bn is! are you by any chance talking about this: https://coinb.in/#newTransaction

in any case, CPFP is Child Pays for Parent and it means a receiver pays the fee of what he received, to put simply.

as a sender it is best if you pay higher fees in the start, and also use opt_in RBF so that you can increase the fee. you can use Electrum for this easily.

but to use CPFP as a sender you can do this:
if your transaction is creating two new outputs (meaning you have a change address that are receiving the remainder of bitcoin in it) you can use CPFP on that.

i am not sure which wallet lets you do that, i have never had to look it up!
but technically you spend that transaction and pay higher fees, this fee needs to cover the fees for the previous transaction and the new one. for example if the previous tx needed 0.0006BTC fee and the new one needs 0.0004BTC, in your new tx (the CPFP tx) you pay 0.001BTC.

it is funny because i remember people saying the same thing last year. they said "i will sell my bitcoins at $1000 because that is a huge profit and price can not last there, it will fall, blah blah." now we have the same situation, price has been staying above $1100 for the best part of last couple of months and that last year's $1000 target for people has also moved up! and it will move up when we reach $1500 and then $2000 and so on!

as long as you don't have some crazy number of TX_In and TX_Out (something like 300) the fixed amount of bytes you add is 10 (4 version + 1 TxIn count + 1 TxOut count + 4 LockTime).

also as long as you are using a Pay To PubKey Hash and also use Compressed private keys (like the address you have in your profile which has a compressed private key) your formula is correct.

"some weakness in implementations of the Elliptic Curve Digital Signature Algorithm (ECDSA)"
in other words: "poorly written code"

a somewhar similar incident was blockchain.info and their Android wallets. they used random.org to generate their random number (i think it was the k value but i am no expert and have terrible memory!) and random.org changed some stuff about their url so the page gave an error page, so all the wallets created at that particular time hit a brick wall and generated the same private keys and people lost a lot of money!

very interesting. i checked via https://data.bitcoinity.org/markets/volume/6m?c=c&exchange=bitfinex&t=b
and their total volume was $3,179,103.85 in the past 6 months and with 0.2% trading fee they can make $12,716.41 (an exchange take fee twice from the one making the order and the one filling it although fees may be different).

to make millions they had to have other ways of making money! margin trading fees, if that is a thing (i have never looked at it!), lending (if they have it), trading themselves on their own platform or other places, also they have altcoins too so we should consider those volumes too.

but it wasn't a FOMO rush buy, or am i missing something! the chart was crazy, it was up and down it didn't just go up merrily to $1350 and drop back to where it started. it was a short term (in matter of minutes) shoot up then dump to even lower prices than start and then back to kind of normal.

edit: i knew there was a picture somewhere. this speaks for itself:

it is both,
it has always been both,
it will always remain both or it would no longer be bitcoin.

and that is the beauty of it. you can use it as a currency as it was supposed to from the day it was created, but since it is unique and it is secure and also there is a very limited supply it becomes a good investment too, as gold if you like to call it.

Memory pool is empty, yaaay.
but is it really?

let's take a look. https://blockchain.info/unconfirmed-transactions shows 3540 transactions in memory pool.
now let's take a closer look.


That is 18 Megabytes of transaction!

now let's look some more:
https://blockchain.info/tx/88c032357d6b0567756cc74515175e83f930a1b5e2d821ba69b1d11c4032ef91
hmm! 59145 (bytes) with 10 sat/B fee.
is there more?
sure there is, AntPool just mined a whole lot of these https://blockchain.info/block-index/1483607
Number Of Transactions in this block = 102

the worst part is, this is not the first time and won't be the last and that is only one block mined by one mining pool, there are more being mined by others.

(i am not an expert and i would love to hear more about this from others but here is my information)

it is all about the signature and how it was created. if there is some weakness in implementations of the Elliptic Curve Digital Signature Algorithm (ECDSA) then there will be a possible way of finding the private key from the signature in the transaction. e.g. using a not-random k value.
this doesn't actually need address reuse. one signature is enough, although i believe reuse makes it easier.

for something sensitive like your cold storage wallet, it is best to use the most popular code. and it is not just because of trust but also because the more popular some code is, the more it is reviewed and as a result it will have far less possible bugs.
i suggest using: https://www.bitaddress.org/ instead. it is more popular and more tested.

lets say the buy orderbook looks like this:

Buy orders (bids)
price....volume
100......2000
90........3000
80.........100
70........6000

if you have 10,000 coins to sell you either have to place an order at price=100 and volume=10,000 or you have to sell it to these open orders meaning
sell vol=2000 @price=100 (8000 coins left)
sell vol=3000 @price=90 (5000 coins left)
sell vol=100 @price=80 (4900 coins left)
sell vol=4900 @price=70 (0 coins left)
and make (2000*100 + 3000*90 + 100*80 + 4900*70) satoshi for example.

in the platform or even through API you don't need to make each single order, just sell 10000 @70 and it automatically fills these 4 orders.

it depends on where in Asia. it is a big place with lots of countries!
here you can see a list of the exchanges out there, try and find your currency: https://coinmarketcap.com/currencies/bitcoin/#markets

also localbitcoins that was suggested is not a place to trade bitcoin as a day-trading kind of deal. it is mostly to do p2p trading as an alternative method and it is riskier and also more expensive.

if true, then you were banned because of constant spamming all over the forum. there is no other reason. and when you quote your old posts try quoting all of them not only the part that came true. specially the mood swings you had on April 12th about switching your statements from BTC to ETH to LTC then again to ETH back to LTC each time calling the one you dumped under-priced as dead.

it is not "exaggerated data"! it is very real and it is happening. and what preev reports is just an API call to these exchanges and it reports what they report, and at this time Bitfinex is reporting  a high price because of obvious reasons that are already stated.
