not always true. most of the times when bitcoin rises the altcoins go down because people pull their money out of the altcoin market to invest in bitcoin and that pulling out can create a big panic among the altcoin bag holders who will then sell and crash the prices.

what i think is that for the past couple of years we have had multiple cases of economical crisis in different countries, small and medium size countries. and each time i have heard at least a couple speculations like this saying it will lead to a bull run because people are going to buy bitcoin!
well to those people i have to say you have never experienced an economical crisis like that! during times like that people aren't looking for a high risk, high volatility asset. they look for a lower risk and lower volatility like gold. not to mention most of them don't even know bitcoin.

however these cases always leads people towards bitcoin as they see the performance and security of it as a currency and store of value. but it is not enough to create a bull run.
also it is worth mentioning that speculation is a different beast! for instance i believe it was Cyprus that had some problems and enough people believed it will lead to a bitcoin rise that they started buying themselves and made the price go up. it wasn't a big deal but it was something.

most of the bitcoin price predictions that i have seen are like a reverse engineering thing. in other words they  first come up with a number (it can be higher for a moon rise or a lower for a drop to oblivion) and then they start coming up with reasons to explain why that is.
in case of electricity usage there is no way humanly possibly to measure it because of the wide range of electricity cost all around the world from less than 1 cent up to 20 cents per kWh and possibly more.

i also disagree with the last part. bitcoin is not yet at its mass adoption stage so it is reasonable assumption that this price is way below the final price that it can have. $10k will look like what $100 looks like to us now. and it is not fantasy!

John McAfee is full of shit, and whatever he says should be taken with a grain of salt. that is how the community should always treat someone who advertises ICO scams to earn money on his twitter ($100k per tweet?)!!!

as for the smaller units i believe majority of people do understand that but some love to pretend they are dumb

you can make a new coin that has 1 mili second blocks and has no fees then say your coin is better than bitcoin but it won't make it so! it will still be a shitcoin that nobody uses so you can make any claim you want

as for centralized coins like XRP you should compare them with their counterparts such as PayPal, in comparison XRP is extremely risky, very slow and has huge fees.

as long as this mentality of yours doesn't lead to becoming a bag holder, you are good to go. but if you start thinking about every other shitcoin the same way and think that you have 1 coin and that 1 coin will always be 1 coin then you are in a lot of trouble. like the trolls of Dogecoin saying 1 Doge = 1 Doge and meanwhile Dogecoin continues losing value and dying.

there is absolutely no pressure on SEC to approve bitcoin ETF! they will reject it if they want to and there is nothing anybody can do about it. i mean they can run social media drama all they want and fill the internet like they always do but it won't change a thing

based on what i have seen those who talk about such ridiculously big drops are either newbies who have missed out on buying buying bitcoin prior to the rise and are not wishing for the good days to come back, and they won't stop at $5k they will want lower, they will go as low as $100 and still wouldn't buy.
or they are just FUDsters trying to fill their shorts and make a tiny amount of profit from a small price drop.

it is "value" not "volume"!

in my opinion although things such as both value and volume as in how much money was transferred through bitcoin and how many transactions per second it processes are great things to achieve, there is another important matter that we should not forget...
bitcoin is the only decentralized currency that has been created. when comparing it with PayPal and Visa you are comparing apples and oranges. decentralized currency with a distributed ledger versus centralized payment processors with a database. they are not even comparable.

the sad part is that people already agree more or less that ETF has nothing to do with bitcoin and are starting to pull their heads out of the sand but still they are blinded by it. this recent rejection was only a part of it, we still have more ETF drama to look forward to which may be the reason for lack of a bull run indicator in the market. people are still partly afraid of what might happen...

because gambling, alcohol, tobacco and other abusive substances are destroying people that become addicted to them but bitcoin is something that can destroy the corruption that can be found in some of the governments and their banking system so as a result they allow the first group and don't have much of a problem with it but they have a hard time seeing themselves lose control because of bitcoin.

it is what everyone wants because it is not about people losing hope it is about weak hands losing hope and exiting the market. and the result is that when the market is empty of panic sellers there is no more manipulation opportunity left in the market so there is no way to go but up.

when the "layman" uses credit cards, Paypal, Visa, .... do they need to come up with things such as "does Paypal dollars have serial number" to understand it?
NO. they use it as an end user.

so stop making things complicated with weird explanations and usage of misleading statements such as "wallet numbers"!

it seems like a bad fee model in my opinion. fee should be set based on  the transactions waiting to be confirmed (meaing transactions in the mempool) not transactions that are already confirmed (the previous block).

this can make the fees shoot up without having any cost for the miners. imagine you are a miner, you easily fill the blocks with your own transactions and pay high fees on them. you'll spend nothing because you get the fees from transactions that never entered the mempool then next block increases the fee by 10%. find a couple of blocks and fill them like this and you'll get yourself a very high resulting fee. and a huge profit because you are earning a lot more now.

blockchain technology is a great technology with a lot of benefits but i think the use cases are limited, if we start forcing it into different sectors and try to adapt them with the technology then we may not get the desired result and we may even end up reducing the efficiency that we already have.

that is not "signal" it is just showing price difference and there is no reason for it to be working. websites like this are completely useless because you won't be able to make anything using them. first there is a delay in the site for showing you the results then there will be a delay for you to act on it and by the time you make a move a bot has already done it 20 minutes go and the "window" would be close.

in case of WEX, there is some issues with their platform and you may not even be able to withdraw or deposit. which is why the difference in price occurs.

halving soooo down the lone. we have a lot of other things to look forward to before halving. for starters we have ETF to look forward to, not its approval but just its drama being over whether it is accepted or not so that we can start the rise.
we have Lightning Network's adoption by exchanges to look forward to. it has been adopted by some merchants and the number is growing but nothing major. also if some of these gambling sites start using it, that would still be great.
the we have other additions to bitcoin such as Schnorr, Mimblewimble,... to look forward to.
on speculation front we have Bakkt, regulations to look forward to and see how they can expand or limit the adoption of bitcoin.

and these are all 2018-2019 events

bitaddress.org is a website and can be hacked. an attacker can technically take control of the domain and put his own link at the bottom of the page though different methods.

the link is this: https://github.com/pointbiz/bitaddress.org/archive/master.zip which is the clone of the official github repository of this project at https://github.com/pointbiz/bitaddress.org
as long as you go there, there shouldn't be a problem. because you are downloading the source code that you are seeing.
in fact you can also check to see what the latest change was and when it occurred:
https://github.com/pointbiz/bitaddress.org/commits/master
as you can see the latest commit was from 2016 which means the source code is not changed ever since and has been used without any issues for more than 2 years.

unfortunately the altcoin market has left a bad expectation among people specifically the newcomers. they look over there and see the pump and dumps and they think to themselves that bitcoin should be the same.
but then they come over here and see things are very different. but until then they will make silly claims like this.

"document" is a wrong analogy for blockchain. it is more like an actual "chain" because everything is connected to each other, every single byte of the whole thing is connected and if you change even 1 byte of it, the whole thing will become invalid and will be rejected by the rest of the network.

the blockchain is the chain of blocks, each block references the previous block and changing the previous one will make a new next block hash. each block itself consists of transactions which are again hashed and put in the block header and changing any transaction will make the whole block invalid. and each transaction itself consists of reference to a previous transaction (with the exception of coinbase tx) and signature + public key of that has signed the whole thing and changing the signature or changing the transaction will again make it invalid.

so you see it is not really possible to "input an error in the blockchain"!
