Vitalik has never had any faith in any cryptocurrency, specially not in his own project because more than anyone else he knows all the things that are wrong with it and how the future looks bad for his project and the price of it.
and i don't know if it is stupidity, or what but he has been admitting the grim future publicly! the first pump he dumped a couple of million dollars right be fore the crash and the second pump (the recent one) he dumped even more.

things have changed a bit, the transactions won't get "canceled" that easily anymore because nodes have increased their "forgetting" time to 1 week IIRC from 72 hours. and even if that wasn't the case "being cancelled" or more correctly dropping out of the mempool was not an easy thing you could count on. a node can simply relay your transaction forever until it confirms.

in case you decided to send with lower fee make sure to mark it as an RBF transaction (use clients that let you do that) so that you have an easier time bumping the fees in case you wanted the transaction to be confirmed faster.

well the pumping season ended!
the season is always good and fruitful for many people but it never lasts forever, there is an end for everything. now there is only drops and dead cat bounces. there is nothing happening in your back, this is the natural order of things. it just seems strange when you see it in action for the first time but after a couple of "pumping seasons" you'll get used to it.

the best way to buy them is not to buy them right now because they are all in bubbles, but it is your decision and i keep seeing you make these topics for a couple of weeks now where you repeat over and over that you are planning to buy ETH, if you want to buy and think it is a good idea then just do it already

for buying these coins the best way is through exchanges such as poloniex and bittrex or any other that you feel more comfortable with their rules and services they offer. and for that you need bitcoin! specially since many of these coins such as Waves does not have any USD markets.

also shapeshift is a good place but the final total fees will be higher and you won't get the benefit of using a trading platform. for the fee details just read the website's FAQ, all of them have all the information you need.

bitcoin is good for any kind of investment both the short term and long term it has enough liquidity and volatility for the short term traders to make enough money from taking advantage of these changes and for the others who don't like day trading they can invest and go for the long term investment instead. price has always gone up in the long term because of what bitcoin offers as a secure decentralized crtyptocurrency that no one controls and has no borders!
this is why many buy and forget for years and become rich easily.

it depends on how much lower and how full the mempool is going to be.
if you pay a little lower fee than what you should, (for example lets say you should have paid 330 satoshi/byte but you paid 270 s/b) it will take a longer time. it can be less than a day in most cases.
but if you pay a lot less than you should have paid (for example paying 50 s/b) then it may take weeks or never.

and the mempool is the memory pool or in other words how many other transactions are waiting to be confirmed and how much fee they are paying. if it is a small number (eg 5K) then you have a higher chance and if it is a bigger number (eg 100K) you have a much lower chance.

yes it was true.

i have not checked all the exchanges to see if it happened on all of them but i know that it happened at least on one exchange. GDAX (you may know it as coinbase). and it was because of the problems that ethereum blockchain had and the fact that all exchanges disabled deposits and withdrawals of ethereum and people started to panic and dump everything they had so price crashed hard.

you can check the charts on GDAX to see this crash.

what i explained above (the additional layer of SSH) is un-blockable. and the only way of blocking it is to block all encrypted connections and that includes https connections meaning all the websites using it (such as banks, ...) will be blocked.
there are additional ways to add that extra layer but i have found that SSH is the best method.

he is not wrong, it is a good idea to diversify and we are all doing it.
but as the head developer of a supposedly big project which you claim to be revolutionary and want to convince people it is good, you should be careful about what comes out of your mouth. for example in this case he is clearly saying i don't even have faith in my own creation.

if you take a closer look at the altcoins you mentioned here as your previous investments you can clearly see that none of them gave that profit to you in long term (1+ year!). in fact all of them have been falling in the long term and causing you to lose money.

then over the period of ~1 month they started rising and gave those profits. so ask yourself this question: why would you risk holding an altcoin for a long term and lose money with the chance of it rising over 1 month and go back down again for another year.

i am not in China but VPN is also blocked in my country.
there are two kinds of blocking so you need to first figure out which one they are using before attempting to get a VPN.
the normal way is to block the websites selling or block ports that VPNs use. in which case using a different port like the ssl (IIRC 443) will solve it easily. usually schools, ... use this on their internal network to prevent students or employees, ... use VPN.

the complicated method is blocking any sort of VPN connection by doing some DPA (deep packet analysis) in which case nothing will work, and buying regular VPNs would mean throwing your money away because you can not connect to any of them. solution is using a VPN provider which offers an extra layer of SSH encryption. the only one that i can remember which offers this service and accepts bitcoin is called AirVPN

it was not -10% then +10% or vice versa at all.
and day trading is certainly not safe in a market where price is falling. it is highly risky, riskier than it normally can be.
the only case where it can be a good idea to invest in such a market is if you see a very huge dip and are nearly sure that price will bounce back so you buy in that dip. but also the profit in cases like this are too small to be worth it. meanwhile in other altcoins price are rising with a much smaller risk and a much bigger profit!

so why you would choose a high risk low reward over a low risk high reward is beyond my understanding!

yeah, the flippening is happening. i don't care and i am dumb. i only look at coinmarketcap.com and if some coin is placed under bitcoin and the rank says #2 then it must be a good coin.
i don't care if the blockchain is bloated,
i don't care if it can not handle transactions properly
i don't care if the whole thing is not even reliable that even exchanges suspend everything to "investigate" as they do with shitcoins with broken blockchain.
i don't care if DAO can happen again with any other smart contract and cause another big failuire
i don't care that smart contracts is the breading ground for a lot of scams and majority of ICOs are in fact scams
i don't care if these scam ICOs will cash out and crash the price soon
i don't care if the transaction fees are extremely high
i don't care if ether has a >75% premine of 70+ million coins
i don't care ...

all that i being dump care about is that the market cap is huge so it must be a good coin, doi. also i read on bitcointalk and reddit that some random account was saying ethereum is good, so he must be right.
here is my money and i will hand it to you on my own.

no it is not a glitch if you look at the volume of that time also the trading history. people did sell their ethers by that time. it was because of a mass panic because of the failure of ethereum blockchain. so anybody who had any buy order on GDAX removed it so that made the buy support thin and then came the panic sell, which is practically a huge amount of ETH dumped on the already thin buy orderbook so it crashed the price easily to $13 but since it is a huge drop obviously everyone jumps in and automatic trades kick in also and buy it back up

he has a good point though.
right now LTC price has tested the high price of last months again and whenever price reaches the same high after some time (the cup and handle) many will consider it as their relief to sell their coins which they have bought at the previous high, hence crashing the price. and this will never go down to $25-30 again. the lowest will be what we are seeing now. and there is a good chance that it will change direction very soon probably in 3-4 days up to a week.
so buying the bottoms is a good idea.

it all comes down to demand!
if people are interested in it somebody will modify the "Vanity Address Project for Bitcoin" and fork it for ethereum. but since there has not been anybody interested in such a thing nobody done it either (at least as far as i know, and searching didn't bring up anything either).

also be careful about using some of these websites or even if you found the open source project forked from Bitcoin Vanity address project in the future, because they may be malicious or at the very least have bugs that lead to fund loss.

your post is completely meaningless because you made a bitcoin transaction but you are talking about USD!
if you want your post to have any meaning you should include 2 things and include both of them not just one:
1. amount of fee  2. size if your transaction in bytes (or simply add fee/byte)

right now my assumption is that you made a transaction with a lot of small inputs and the size of your transaction is more than 5000 bytes!


i believe OP sent a transaction FROM blockchain.info TO exodus, which means blockchain.info costed that much fee and they have been suggesting 120 s/b for all transactions so far!!

it means nothing really because this is not a new thing. it happens every year.
each time there is a good altcoin pumping season where all the altcoins get pumped a lot one after another and they give a lot of profit to most old users who know the patterns and those good traders who don't fall for the lies. and the rest who lose money either become experienced and next pumping season they make good profit or they just leave.

and besides this is just the start of the altcoins dump. it will speed up soon and that is when things become catastrophic for them.

what do you mean by OTC? something like peer to peer exchange, off exchanges and selling to people, like what they do on localbitcoins?
if that is true, then i don't think you can call it "arb"itrage trading anymore. it is just buy low and sell high to people who don't want to go to exchanges to buy cheap! it is more like a business, and you have to gain "customers" by building up some reputation.

it is mostly money which is going from altcoin to altcoin. the wise money (or wise investors) invest in an altcoin while it is low priced and then pump it, as it grows others will join and on top the wise money exits the market to go to the next and those who came in late will stick around begging for a way to exit. this process can be fast in shitcoins and it is slow for better altcoins such as litecoin but it happens for all of them.

and for bitcoin i believe there is some glimmer of hope for the August thing since SegWit has gained >75% support which is more than 90% if you add SegWit2x and SegWit signalling.
