believe it or not, things in the real world are not like "either this or that" aka black and white. there is a whole lot of possibilities that can happen. not just either replace fiat or be dead situation!
bitcoin is a currency and will grow as such. it will be used more as a decentralized money by many, it has already started slowly and got fast when Japan adopted it as a legal way of payment and removed the taxes on bitcoin payments. however the Japanese JPY didn't die or be replaced by bitcoin just because people are now using bitcoin as payment! they are working separately. and both are beings used.

i know what happened, he was too busy making useless youtube videos and then spam advertising them all over the internet so that he can gain some views and make some money, and he forgot to learn the first basic thing about security regarding his bitcoin wallet.

it is called cold storage https://en.bitcoin.it/wiki/Cold_storage
there are lots of useful things to learn on proper websites like the wiki and some others. stop wasting your time with those youtubers.

obviously the decentralized exchanges!

of course it depend on how the decentralized one is designed and how you use it but when we talk about decentralized exchanges it means you are going to be in control of your cryptocurrencies and remain like that during your trade. this means there is no account to block, there is no one to run away with your money and no way to get scammed.

but in centralized exchanges, you give up control over your money and the service owners become the owner and controlled of your money. they can block your account, rob you, run away and there would be nothing you can do about it.

what fall?
normal fluctuations are not called fall. they just look big to you because you are looking at the numbers alone not the size of the change. what you are calling "fall" was about a 3% change and nobody bothers to make profit from 3% in bitcoin that can have >10-20% changes in a couple of days or while altcoins are around that can change 200-500% in a day.
also this is more like a double top. price tested the resistance twice now and now the support is being tested. soon we will see price break out of this channel and go above the line ($8000+)

because of the full mempool and your low fee, some nodes were probably rejecting your transaction which is why it took a little longer for it to propagate.
as @HCP pointed out the transaction size is huge and this size is due to so many transactions that you are spending.
in any case i have accelerated your transaction for you, it should be confirmed soon enough.

bitcoin confirmations are always at the same speed! they are as fast as the time that it takes to find a block which is 10 minutes on average.

what is changing is the fees and because of that the priority that individual transactions get.
the fees change based on how many transactions are being made and how many of them are being confirmed. recently because of a temporary big drop in bitcoin hashrate, fewer blocks were found and as a result less transactions were mined. additionally due to price dropping many bitcoin transactions were made all of which caused the mempool (number of unconfirmed transactions) to grow.

this means a competition to get higher priority by paying higher fees.
and none of this has anything to do with "confirmation speed"

now this is different from your initial mistake for missing the () in front of the functions.
this new error you received and posted here is a known issue with this particular version (Electrum 2.9.0), when you use console in this version it looks for password by mistake, that is why you are getting this not-user-friendly error message.
it should be fixed in 2.9.3 https://github.com/spesmilo/electrum/issues/2684

always try to use the latest versions. ie V 3.0.2

technically speaking if electron cash had no bugs or malicious intents, there shouldn't be any problem when using it. because you will be connecting to bitcoin cash nodes an also your wallet will create a transaction that is only going to be valid on bitcoin cash network due to replay protection.
i have not yet used Electron-Cash to give you any feedback though.

as for transferring bitcoin, you can still send with a transaction 10 satoshi/byte and use ViaBTC accelerator to get it confirmed. you may need to try every hour on the hour to be able to get in though. or wait for the mempool to be empty again and send with much lower fee.

the bitcoin price was not exactly rising fast, it was coming back to where it was supposed to be and that come back was fast. the issue is that they keep repeating "bitcoin is a bubble" that you start to believe it, but when you check the reality you can see there has never been such a thing as a bubble in bitcoin.

that means the drop was an artificial lower price and against the demand, and when you go against the market you can not keep it that way. it will "jump" back up fast.

apparently when you use 2FA in electrum (your sending address = 3GmVu....) with TrustedCoin, you are charged a small fee for using their services. it works just like this transaction, there is always an additional output added to your transaction which is paying for their services. and the amount of it is usually 0.005BTC.

read the second paragraph when you start a 2FA wallet:




also for more detail you can read the "How much does it cost?" section on their website: https://api.trustedcoin.com/#/electrum-help

that is why we always say "don't keep coins on exchanges, and don't invest what you can not afford to lose". all these centralized exchanges are untrustworthy. it has happened multiple times, they scam their users and get away with a lot of money. one of the reasons why i don't care much about my similar issue with bittrex is that i wasn't holding much there.

my guess is that they had some money troubles and saw the opportunity to seize a large number of accounts and their money. probably invested in something that tanked hard and they lost a lot of money.

things never go as people wish, but they always go as they are planned.
the FUD about some shitcoin replacing bitcoin has always been around and it has been used a lot. the word "flippening" however was used by the ethereum advertisement team. and each time this method is used, the said shitcoin is pumped a lot. in case of ethereum they pumped it to 0.14BTC, in case of bitcoin cash they pumped it to 0.34BTC and surely enough, each time it only lasts a short time before the dumping begins. that is inevitable.

it is all good though! it helps us, the early adopters to earn more bitcoin as long as bitcoin is cheap. to have a bigger stake in this scarce currency when the mass adoption is achieved.

whenever a country talks about getting their own cryptocurrency, it is exactly the same as them printing more money (physical cash). it is a centralized and fully controlled and limited to one country currency.'
now you are comparing this to bitcoin which is a decentralized and global an not controlled currency with a limited supply. i am sure a country-coin will be limitless like their fiat and they will be issuing new tokens whenever they want just like how they print money whenever they want.

if they try to fork bitcoin now with
- no replay protection and
- no miner support and (it currently has 5.6% hashrate signalling which is the leftover who has not yet upgraded their servers it has nothing to do with support)
- not community support and
- no businesses support

they will be embracing themselves. who is the hashrate anyways? checking the stats, there are no miners left who are signalling for SegWit2x anymore!

did you read the topic carefully? https://bitcointalk.org/index.php?topic=2059091.msg20545296#msg20545296

besides, you just have to create a new wallet in your bitcoin wallet with a new seed and transfer all the funds to the new wallet and then import your old seed which is not empty of bitcoin in the electron cash wallet.

if you are too paranoid (like me) and want to make it 100% safe then use it offline.
this means you import your addresses (not private keys) in an Electron-cash wallet, make the raw transaction, then transfer it to an offline system where you have installed another Electron-cash wallet with your private keys imported there, then sign that transaction to transfer back and broadcast.

your issue is not because you traded shitcoins but it is because of your bad timing.
the shitcoins also get pumped and dumped, you just have to find when and enter as fast as possible and hen exit just as fast.

for example there was this shitcoin called MoonCoin or Moon for short. it was worth less than 1 Satoshi (about 0.1-0.08 satoshi if i am not mistaken) and earlier this year it was pumped hard up to 5 satoshis and that is nearly 5000% profit with a large enough volume to make a lot of profit out of it.
i caught it mid way up and made some small profit from it because i didn't have much on the exchanges which listed it.

the console is answering you itself. if read the last line it is saying you must use help() instead (in other words use parenthesis in front of your functions)

if we made a new vanity address called 1BBLChart..... and each of you who post this "bubble stages chart" send 100 satoshi to that address (assuming 100 satoshi transactions would be possible) then that address could have had 10BTC in it.

what none of you realize is that we are not even in the second phase yet. you think the "media attention" has happened already? not at all! they are still laughing at bitcoin on the media most of the times and call bitcoin "Fraud" and things like that. this attention has grows a lot but it is not even near what that chart is saying.

i disagree
these aren't really "game changing"! for example the premined BTG is not even worth considering. the useless bitcoin cash which only gets pumped and dumped is also the same. and the S2X fork was expected to be something like this.

in other words pump and dumps started for the millionth time because they found an excuse to pump a couple of altcoins including BCH.

it wasn't money migration, people never sell bitcoin then use the fiat to buy bitcoin cash. instead they sell bitcoin and buy bitcoin cash directly in the BTC/BCH market.
and the reason for bitcoin drop to $5555.5! was manipulation and FUD and the panic that followed. the price dropped about 30% like all the previous drops under same circumstances...

it has nothing to do with "gold" but the name.
and lots of different exchanges have already announced their support for trading BTG a long time ago and people have claimed, dumped, and traded their bitcoin gold already!

bitcoin cash had a lower difficulty which meant it was easier to mine it but because of the lower price nobody did. but they started pumping bitcoin cash that meant it became more and more profitable to mine it at a lower difficulty and since bitcoin and bitcoin cash are alike in mining, miners switched to temporarily miner BCH and make the big profit.

when hashrate leaves like this, blocks are being found with a delay. less blocks, less transactions being mined in total every day, more transactions in the mempool and finally higher (increasing) fees.

but ever since the pump of BCH ended and price of it  started falling the hashrate also came back and now things are going back to normal. but it takes time for the negative effects to fade away completely.
