i believe it will be implemented only if it can gain enough support.

the effects of implementing SegWit on bitcoin is pretty clear. there will be a rise.
the effects of how to implement it is unclear. it can be a smooth transition with majority support or it can be a hostile change with low support and a risk of chain split.

no it is not.
the fluctuations are normal and they happen every time after there is a rise. price becomes stable between two high and low prices where people who don't know what is happening are becoming confused why bitcoin is not rising 24/7/365!

do you have a lisp?

fork does NOT mean automatically we get two coins!
there is a small chance a split happens from any kind of fork and if that happens because of how big bitcoin is i expect one of the chains to die soon and we will be left with only one chain.

there are many topics on this. please use the search function!

you have to ask Coinbase.

i explained this already.
it depends on how the fork is going to happen.

No, no well known, or little known or even unknown company accepts altcoins. there are some small businesses online that are accepting old good altcoins such as Litecoin and dogecoin but nothing else.
however you will find a lot of falsified news saying some big company like Microsoft for example is accepting a shitcoin. for example all the lies about Microsoft accepting ether on the news sites. but you always need to check their official website like Microsoft.com and see for yourself. the only cryptocurrency that Microsoft accepts is bitcoin.

you can see it here: https://support.microsoft.com/en-us/help/13942/microsoft-account-add-money-with-bitcoin

there are no hidden addresses in bitcoin as far as i know. he may be confusing the red text on blockchain.info which says "unable to decode" in the address field with a real address.
but that is not a bitcoin address, it is an output, a special form of output that blockchain.info (or possibly other block explorers) haven't coded in their system yet to be recognized.

the only type that i know of is the OP_Return which is used to embed arbitrary data on the blockchain. they will look like this one:
https://blockchain.info/tx/c83c11c849e7a9d317eec44a07b6aa7dd4328508f3d6117ac6a29c256453196b
which has a url in it (http://www.usnetads.com/view/item-129488291-Wedding-in-time.html )

no we don't know that with certainty.

who said BTC is going to split and who said it is going to split into BTU?!!

seems to me like you are certain about things that everybody doubts about (things like fork and split, and investing in pump and dump altcoins, ...) but you are doubt things that others are more certain about (things like buying bitcoin or not)!

whenever price of bitcoin goes up everyone starts to bring out their big guns of speculation and call a different high number. some of them have some good points and some are just throwing numbers. haven't decided which one this is.
but it is not a big thing really to doubt. bitcoin does have the potential of going that high. there is still the same limited number of coins available and the max amount has not changed
and demand is still rising for this limited supply.

Thanks for the payment

the fact that price of something is still over something doesn't mean it will rise. it may rise is different though. with the things that are going on with ethereum the chances of that "may" are very small.
and with all these ICO funds that are ridiculously big numbers and when they start liquidating these funds the chances of a crash become even bigger.

and since this is all speculation, you are working with this chances, and chances of a big crash is higher than chances of any kind of big rise.

and here is your "no sign of increase"

here is another picture then, just to make you more "interesting"

this is the Electronics Retailer called Bic that is accepting bitcoin with the banner saying tax free corner!

the only reason i can think of, specially when i see someone who doesn't even know how to fork a github repository is to gain some "free money from the gullible masses". there really isn't any other reason for newbies with no knowledge about anything whose whole experience is a random article their read online on "how to create your own altcoin" to make one.

although to be fair there are a couple of good projects out there that were created by people who wanted to "innovate" and they were also successful to some extent but mostly lack the power to advertise their project.

yeah, i have tried it a while ago to find some kind of list but i think nobody wants to do it because it is scary. i don't know the source of ~$1 billion dollar that adaseb said in second comment is and how close to reality it is but that money is certainly going to get out of "being locked" soon and hit the exchanges and crash the price. so maybe this is why everyone is keeping it under the radar for now.

i didn't say i "predicted it" i said i was nearly certain.
i always say it is about chances in trading. when price was testing the $3000 resistance i decided the chances of a drop in case of failure to break it is higher. so i sold an affordable amount there to make some profit.

could i have been wrong? absolutely yes.
i was thinking the same around $2000 too but the resistance was broken easier and i help off. i was thinking the same all along and i missed the selling on a lot of occasions.

and even if was wrong and price went above $3000 i wouldn't have minded. i was still selling at a big profit and would have bought back what i sold at higher price to enjoy the rise. and as i said it is a "small portion of my stash" so even if i don't buy it back i still have more

a couple of exchanges adding a new altcoin to their platform in order to be traded and make more money from it doesn't mean China is legalizing ethereum.
and on top of that when the news is coming from a known shitnews website called cryptocoinsnews that means it is total bull crap

to be honest of cryptocoinsnews published "sky is blue" i wouldn't have believed them!

the biggest challenge which i think most people would agree about is reliability of that platform which you are using to trade.

we all know the hacks and the risks of one of these exchanges either get hacked or scam and say they were hacked. and that is why it will always be a huge risk and a headache to keep coins on exchanges for simple trading.

the other problem about not being reliable is the fact that these exchanges go down, slow down, ... during high traffic. we have already seen this one too. many times. you want to sell when you notice a dump but the exchange becomes non-responsive and you lose money because of it! and this happens to big exchanges like poloniex, coinbase, ...

all these things hard bitcoin but the are not the reason for not being at $10K yet, they just slowed down the rise to that price, they never prevented it.
$10K price still needs a lot of adoption a mass adoption actually and that won't happen over night or in half a year. Japan started adopting bitcoin like this only this year, it needs time to build up towards that $10K.

i say even if all the debates and bullshit didn't happen, we would have been at $3500 tops and nowhere near $10K yet. because you can't really expect a 900% rise in one year for bitcoin any more.

most of what you see are pools not mining farms. and these are different. a mining farm is the one owning the hash rate and the pool is just a server or a bunch of them where these hash powers are connecting to each other to "pool the work".
and mining is not as centralized as you may think. if you do some search (which is a bit hard because information is scattered) these miners and even pools come from all over the world. they aren't really ALL in a single country.

and as for risks like a veto that you mentioned, they can do that but you need to understand that miners are just employees not the network. they matter so little. the real important part of the network or the back bone is the nodes. they decide what to veto not the miners.

for example you can check BIP148 and 149 aka UASF or the proposal to change PoW for more information to find out why miners don't really matter. (although these proposals aren't great and i don't like them but these are solutions that can be used against any possible miners turning to the dark side )

it has nothing to do with etherum, because even before ether there has been ICOs and also there are many other platforms to make smart contracts and start an ICO on. and it will eventually die because it is a shady way of making money which attracted a lot of scammers and it will eventually end badly and when people started losing big amounts of money because of getting dumped on they will stop trusting these scams like they stopped trusting premined coins scams.

and i seriously doubt any legit company would ever go near ICO or making anything of their own. it is not exactly a legal and regulated way of doing business you know.

back to where it really belongs meaning below 1000 satoshi. it is a very simple relationship between supply and demand. and Ripple while having almost no demand but it has a very large supply which is the doom of it.

no. because of what i said above.
and also because i never hold any altcoin. i see no reason for it. they never rise in long term. all the rises majority of altcoins ever had in the history has been a short term rise. and i can easily join in that and always keep the profit in bitcoin that i trust.

sorry to disappoint you but there has not been any dips or a bubble ever since price was at $2900+ and that was a mini bubble and the correction dip already happened.
what you see how is just fluctuations when price moves between two channels and weak hands are shaken out.

i also believe that SegWit2x changed all the market behavior from being completely uncertain and moving towards a bear market to being nearly certain and starting to accumulate instead for the bull market.

there is not should and absolutely no guarantee. waiting around can mean missing out on the rise and buying can mean missing out on the possible dip. you should do something in the middle.
no amount of analysis can predict any future price and when it comes to bitcoin they are even more useless.
it is good that you are using it but you should never rely on them. also i believe your RSI may be a bit low by a couple of $100

if you are lazy and want a good and fast way of doing things then buy a hardware wallet. and since you are planning to invest a large amount of money then i guess you wouldn't mind paying the price for a hardware wallet.
they are safe and makes things easier for you.

but if you don't want to spend anything then you can always go to bitaddress.org and make a paper wallet or you can go to electrum.org and download electrum wallet and install that as your desktop or offline storage.

being slow to answer is bad but i wouldn't call it "worse support" because at least they answer you at some point and your problem will be fixed eventually.

a worst support in my opinion is when they not only never answer you but also they don't care and they don't fix the problems. and with that definition you have Yobit as your only candidate. 90% of their wallets are dead and they have countless wallets listed. the remaining 10% wallets only have funds in a handful of them such as bitcoin, litecoin, dogecoin and the rest are either empty or fake. good luck getting an answer apart from "it will be fixed soon" out of them
