You should keep in mind that this value (although an indication of lack of security of altcoins) is not the most accurate. That's because the exchange has to come up with a number that serves multiple purposes:
- provides them with some security
- compete with other exchanges so that their users don't switch to the other place
- doesn't take longer than the trader would normally wait without complaining

I would also like to clarify that for certain altcoins without an immutable blockchain (basically any altcoin that has reversed blocks or can do it easily due to centralization) the minimum number of confirmation is infinity! meaning they are never 100% safe regardless of how many confirmations your tx has.

You should have used a better example because Ethereum is just as bad as any of the other shitprojects if not worse. Lest we forget how they reversed a lot of ethereum blocks so that they could save their own ass when they lost a lot of money in a "bet" on DAO made in their own flawed protocol. They didn't even fix the flaws, they just reversed the blocks to get their money back!

Then what is ForEx used for?
People are already speculating on all fiat currency values. The more volatile they are the more they will be speculated on.

It's about age and maturity. As I said, gold has existed for thousands of years and have been considered valuable for a long time but bitcoin is a toddler in comparison.

"Used to be".

People's belief doesn't come blindly, it is based on the utility that medium of exchange provides them and its supply. If bitcoin, like any other form of money, stopped providing utilities that gives it value then it will lose that value and could even become worthless.

It depends on the size, it could be an extinction level event in which case who cares about price of x and y because humanity will no longer exist

And how did you come upon these addresses? Did you by any chance get them from a scam "brute force" project?

Public keys are never outdated and there hasn't been any updates from the very first day that bitcoin was introduced which would affect the keys. In other words any key generated in 2009 is still valid today and can be used.
In any case you need private key to spend coins not public key.

What do you mean by this? Private keys are 32 bytes but wallets don't show them as bits, they convert them to a human readable format using base58 encoding and call them WIFs.

Keep in mind that security of revealed 24 words out of order is still not as high as security of a private key because you are revealing your entropy and 620,448,401,733,239,439,360,000 is 6e+23 whereas security of a bitcoin private key is 2¹²⁸=3e+38.

Keccak256 digest is 256 bit but the ethereum addresses are truncating it to get a smaller 20-byte hash discarding the remaining 12 bytes.

If by "protocol" you mean the consensus rules, it does not even look at your outputs, they can contain arbitrary script that is not even valid. But if by protocol you mean the standard rule, it is rejected since we don't have the OP not because of the size since we have similar outputs that contain 256-bit data like P2WSH.

It doesn't have to be OP_HASH160 but it has to be an existing OP like OP_HASH256. Since we don't have OP_KECCAK then it is not possible to spend the output that uses a keccak hash of the public key under normal circumstances (ie. no collision!).

Possibly a test using the same hash without having the corresponding pubkey.

I wonder how something like this could work considering the fact that any information provided based on hashes that could reproduce the keys could be duplicated by the other parties that are trying to steal the same coins.

The same as any other output script but instead of using hash of public key you use the same public key. It could be reused or the wallet could produce a new pubkey for every new payment (which was the default).

It is badly merging two different statements.
1. Iran is always fighting illegal miners who are mostly stealing electricity to mine cryptocurrencies (with basically free electricity). The operation against them is always intensified during summer since the electricity consumption naturally grows a lot.
2. Power is supposedly going to be cut for undefined period to legit miners with licence like some other industries to pre-plan for the natural increase in electricity consumption.

That is nonsense. Iran has the biggest gas reserves in the world and is currently extracting the highest amount per day, that is more than we can use and most of it is being exported.

The problem is that manufacturing of new power plants hasn't been as fast as speed of consumption increase. For example the construction of the 2 new nuclear power plants would take another year to finish which is normal but still it can't keep up with the consumption. There are 2 more under construction that would take longer than that.

That is partially nonsense. Energy in Iran has always been cheap because we have the biggest reserves in the world and extraction of it is easy and the quality is high (eg. the oil is light and doesn't need much effort to extract). Also due to exchange rate and the sudden drop of it 4-5 years ago the cost becomes a lot smaller when converted to dollars.

You are focusing on other aspects of bitcoin and you are right but the point was to focus on the "currency" aspect of bitcoin and as a medium of exchange it is the same as any other medium of exchange namely fiat.

You are naive if you think any "asset" exist in the world that has a stable price! For example gold that people think is stable, is not stable at all. It's just that gold that existed for thousands of years is not not as volatile as bitcoin that existed only 13 years. Otherwise gold has gotten dumped hard and pumped hard. They also recently found a massive amount of gold that they are going to extract and enter circulation that could dump gold price in the following years to come!

Again you didn't answer my question, fiat is not backed by anything so why should bitcoin?

It is not bad, it is an opportunity to buy bitcoin at a huge discount.
It is also not the beginning of the revolution, technically that was 2009 when bitcoin was introduced.

This is a clear example of what I warned about years ago. People look at "crypto" aka shitcoins and then judge bitcoin based on those shitcoins.
A large majority of altcoins have been dying longer than the recent dump and a lot of people have been celebrating this purge but only a few like those who you named are associating that with bitcoin to try and discredit bitcoin just because altcoins are shitcoins!

That also attracts scammers. Lets use your example about dotcom bubble. The internet (aka the underlying technology that started all of it) wasn't bad or scam. It was an innovation that changed the world and it is widely used today. But a lot of garbage was made using that technology and people were scammed out of their money.

It is the same with bitcoin. Bitcoin itself is the innovation and the technology that started all this but a lot of scams are being created using that technology to rob people. When the scams are pumped and the altcoin market grows to be worth trillions that doesn't mean we are looking at a booming technology market! It means we are looking at a massive scam.

What are those utilities, can you name some of them and have you even used any of these supposedly more utilities yourself ever before?

You see it is not enough to say the shitcoin provides a utility, that utility has to be needed and be used. For example I could create a shittoken and claim that if you buy it, the token would cure cancer. But that doesn't mean it does provide that utility!

Your sources were misleading. In fact bitcoin has the fastest and cheapest transactions in existence even compared to traditional payment systems including your bank.

What you have to first realize is that "confirmation" is a measure of irreversibility of a money transferred not just an arbitrary number. With that clarified you can easily see that bitcoin has the fastest transactions because on average each bitcoin block takes 10 minutes to be found and 1 confirmation is providing a huge amount of security.
Compared with traditional payment systems, they usually become irreversible after months! That is already millions of times slower than bitcoin.
Compared with altcoins since they don't have nearly the same security as bitcoin, specially shitcoins that have mutable blockchains like ETH and BCH, they are never secure and best case scenario is to have thousands of confirmation that would take days and you may still not be nearly as safe as having 1 confirmation on your bitcoin transaction.

Those are terrible definitions if you ask me.
Basically digital currency is any currency that doesn't have a physical form, so it includes your online banking system, your debit/credit card, your PayPal, bitcoin, shitcoins and even tokens.
But a cryptocurrency is supposed to be a currency that relies mainly on cryptography and blockchain technology although some altcoins don't follow this definition exactly. Meaning a lot of them are not currencies or some of them don't even use a blockchain.

Another factor that would affect the decision whether to lock the coins or not would be the total amount that would be affected by the vulnerability. It is not just P2PK outputs, it is all the reused addresses that have revealed their public key and still have a balance and all the new outputs that start using public keys again like P2TR outputs or any other output type that contains public key like P2MS. For example if it affects a quarter of bitcoin total supply (5-6 million BTC) then it is a serious issue to let them be "stolen".

It is far more complicated than that.
It starts from the fact that US has been on a downward spiral and has been getting weaker every year. Even the colonies are recognizing this so they are increasing the pressure on US to get more benefit from being a colony. For example US hasn't sold any medium+ range weapons to any of them so they filled the gap with China, that angered US but they couldn't do anything about it!

I strongly disagree. It is just that US weapons have been grossly useless and it has been proven many times. For example when Yemenese attacked these Arabs none of the defenses that US had sold them worked. You are saying that the Arabs don't know how to use them but what about when the same people attacked US bases in Saudi Arabia and the same weapons operated by US military personnel protecting US military personnel also didn't work at all?

It is the Persian Gulf and the name should tell you who rules it. The 19 Greek ships that are not allowed to leave it because they seized only one of our tankers should also tell you who has the last say and what US can do which is nothing.
Those teeny tiny countries you are talking about such as UAE, Bahrain, Qatar and Kuwait are fake "countries" that were created to be Western puppets. Some of them don't even have as much population as one of our small cities nor have enough history has some of the trees that have existed for centuries in Iran! Nobody cares about them.
Only Saudi Arabia is a big player but we also saw what happened to their oil production when the poorest country in ME attacked them and cause their oil production to be cut by half!

Keep in mind that you can't really compare 1973 with today since that is before Iran's revolution which means it was before Iran stopped being a US colony.

P.S. one more thing I should add is that even these colonies don't listen to US anymore. Recently they rejected their boss's demand to sanction Russia and they openly said they are going to continue their good relations with Russia and they are also getting close to China which is against another demand of their boss

This was actually started by Iran years before Russia even thought of it. Right now we are discussing usage of a new currency among the Eastern block that could be something similar to euro.

Beware that you have to find a good balance between selling, buying, buying back and HODLing. After all using exchanges is always risky, trading is an extra risk on top of it. I personally dedicate a small portion of my bitcoins to trading which is why when Bittrex scammed me and stole my coins I wasn't devastated, that was simply because I was trading with a small amount that I could afford to lose.

If you get over that, trading could give you some good profit. For example I sold a small amount above $30k and bought back above $20k and I'm happy with the profit I earned regardless of what the price currently is.

Money does not need to be "backed up" by something. In fact no money in the world is backed up by anything. Take US dollar for example, it is not backed up by anything except a stupid faith 70 years ago. So the real question you need to be answering first is why should bitcoin be different from other currencies?

One funny thing about big bitcoin price movements (not just drops but also rises) is that we hear new names that we never heard before in bitcoin circles. Idiots who start predicting the next price and their opinions are spread on the internet as if it matters!

The real question is why does bullshit of a local TV personality even worth repeating in a speculation board?!!

A lot of weak hand newbies were purged from the market when the big crash occurred but the problem with irrational market behaviors is that they are going to continue being unpredictable so my vote is the last option.

I think everyone would love that but the problem is that as soon as bitcoin starts rising back up again, the shitprojects would also start being created or existing ones be pumped and dumped again.
