it probably means that you have already made one transaction previously that is not yet confirmed (in other words it is currently in the mempool). and in your new transaction you are trying to spend the same funds again (same transaction output) or in other words you are attempting to do a double spend.

i just saw the Yobit email to me reminding me about their investbox and the new (stupid) rules of it.
apparently now you have to roll the dice on the coin you invest, 5 times each day in order to get the profit of that day. as if things weren't desperate and shady already.

and we all know that their dice game is not provably fair at all so you might as well give them your money!

are you planning on adding bitcoin cash to your exchange?
it is already listed on most exchanges and has a decent trading volume so far, i'd like to start selling and then trading it on c-cex if possible.

you shouldn't really be asking others to tell you whether to sell or not.

as a trader, you should look at the market and see its movement and which way it is moving, then make a decision based on that and also based on the price you have bought your coins (your entry).
if you are nearing the loss then you should already have a stop loss and should have already sold them.

and in case of altcoins you will be losing precious time by asking around!

this is actually getting pretty interesting!
the blocks on bitcoin cash are being found ridiculously fast. and that shows it is more like a surge of miners who waited this long until the hashrate drops first then start mining it so that they can mine at a lower hashrate and find more blocks.

you know what this means, they are only looking for that 12.5+fee reward to dump.

the more interesting this is to see what will they do after the difficulty went back up again and it stopped being profitable at $500 to mine bitcoin cash.!!

surprisingly well actually!
i have been seeing a lot of localbitcoins activity, and also i keep seeing a lot of websites being created to act as exchanges for local currency where people can register and buy and sell their bitcoin. but the prices are not good yet, there isn't enough competition yet.
in any case the adoption is widespread.

it is not exactly "supported by the USD" that is a common misunderstanding just because the price is always 1 USD. well to be exact it is not even always 1 USD, it is known to drop. and the worst part is they don't even promise the price to be 1 USD!!

as someone said it is more like IOUs.

i personally don't trust it at all, although it is useful from time to time. so i won't just dismiss it completely.

mostly charts because that is all i have ever needed and they give you more information that anything else can.
and then there is news and hype that is in the community. for most altcoins that is almost key in their pump.

it is a terrible idea. they are never good, they just will fool you into buying something that they have already over bought so that they can dump on you and get rid of their bags.

you have only ONE bitcoin and will always have ONE bitcoin no matter what is going on in the world of cryptocurrencies.

what you additionally have is an airdrop. there are actually a lot of them. at least 8 of them are currently running and you can claim them as long as you (1) hold your private keys (2) had any balance in those addresses prior to certain block heights.

the active airdrops that i can remember are as follows:
BitCore
Byteball
Bitcoin Cash
Stellar

it has nothing to do with what miners do. they do what they do for the profit they can earn. and they choose the most profitable coin to mine, it can be bitcoin cash temporarily too.
bitcoin cash will never succeed because it is not solving anything! the block size increase they did is like a useless band aid they put on 1 MB block to temporarily take over the public opinion.

if articles were true bitcoin price would have been $10,000 back in 2014 because they were saying it will get there then.

and the only thing i have to say to this is that i am sad because i never placed any buy orders at those prices and now i have missed the chance to buy cheap bitcoin from newbie panic sellers as price is currently above $4000 once more

that is only because of the recent pump that whales did in the past 30 hours (about 82% pumped) combined with the fact that they manually changed the difficulty and reduced it a lot.

but you still need a large investment in ASICs for mining, a cheap electricity, a place to run a mining farm or at least a couple of these to produce enough hashrate and the willingness to take the risk of doing it because you can not spend a coinbase transaction (the mining reward) right away. it needs to mature and price of BCC is very unstable.

if by fall you mean a correction then it happens 3 days ago. there was a 13.6% correction when you were still in your reverie thinking when will it fall.

if by fall you mean drop hard down to some low price like $1000, or something then it won't happen, don't hold your breath

not necessarily.
as i said a correction happens all the time, it is not called "coming down". it is simply a correction as the name suggests.
what you have in mind is probably a comparison between bitcoin and pumped up altcoins which die after the pump. they are very different. don't be confused.

it really depends on what you think of bitcoin. it can be many things at the same time.

for some it is just something they trade. they buy it on each dip and sell on top and make a living out of this. it doesn't matter if price is $4 or $4000 they will make that fiat profit and get out.

for some it is the currency that is decentralized and gives them that financial freedom they want. the fact that nobody can tell you how to spend your money is awesome
these don't care about price. it is the utility that is important.

i don't think that everyone who is talking against bitcoin, specially a journalist, is trying to buy bitcoin at lower prices.

this is just a "hot story" for the journalist, nothing more. it brings them more publicity and as they call it a "click bait". right now the price is very high and the chances of a correction is high enough. writing such articles is good timing since people are also looking for such things no matter how right or wrong it is.

i say they shouldn't.
we really don't want more speculators who are only interested in fiat and how much more of it they can gain through bitcoin. and most of them want this to happen overnight!

think about it, what do we really want?
more investors who will dump bitcoin on every turn and short it to make the most or regular users who contribute to the economy by understanding bitcoin as a currency and use it as such or hope to use it because of what it offers while gaining the profit just because they are early adopters.

for short term the risks are currently higher since bitcoin price has been rising with little stop so far it may need a longer correction than what we just saw in previous days.

but for long term investment, there is so little to worry about as bitcoin price will rise in long term for sure.

hmm, this is very strange! i thought they have already been accepting bitcoin payments! i guess i have always seed their donation address here: https://protonmail.com/donate and made the bitcoin donation once so i automatically though they do accept bitcoin payments too!


the donation address already has received 175BTC

thanks for sharing this man. this is something that needs to be mentioned that this type of rising and seeing such high prices are not out of ordinary.

and i would like to add 2 things here:
1. this share has gone up $73,800 in its first 8 years
2. today the price went up $1205.00

your question is wrong.
you should be asking "when" will bitcoin go past $5000 not "will it". it is obvious that some day the price will get there as it was obvious it will get to $1000, then $2000 and so on.
it is the growing adoption that leads to this constant price rise. but since it is a time consuming process, it can take a while before we get there.

good news is $5000 is not that far. and we are on the way up right now.
