1321  Bitcoin / Bitcoin Discussion / Re: Why blockchain taking days for BTC confirmation? on: May 15, 2017, 06:20:53 AM
it depend on fee and i doubt it take "days" to confirm because after 3 days in the mempool it would return to your wallet if not confirmed

if you pay zero fee it will probably be rejected, and for sending $1500, it depend on the size not on the amount, check the size of your transaction if it say 226 bytes just set the fee to 50k satoshi it will be confirmed fast
1322  Economy / Speculation / Re: will bitcoin reach the $4000 mark this year ? on: May 15, 2017, 05:54:57 AM
considering all the traction bitcoin is gettign and all the recent regulation and adoption, i'm confident that another pump will happen, and above $2k is more than possible, but $4k at thi s slow rate would require too many months for this years

i can't see this happen unless a huge spike will occur, which is not good and would mean a dump and return to the previous value in a short time
1323  Economy / Economics / Re: Moment for buying or selling? on: May 15, 2017, 05:50:40 AM
i find that the best moment for you to sell is when there is a consolidation, you can tell that by looking at the resistance and the value at which the majority are buying

when you see that they are buying always at the same price point and the value look solid, that is probably the bootm, and from there there are high chance that will increase, you cna buy safely

correct tiem for selling is more complicated, there is no way to know the top, you can try to predict it via mental barrier, like for now $2k or before was $1500 and so on
1324  Bitcoin / Mining speculation / Re: 400 watts of free electricity. What miner to use ? on: May 15, 2017, 05:46:51 AM
Thanks for all your replies.

I already had a spare computer, so I ended up buying a Radeon RX480 to mine altcoins and exchange them in Bitcoins.

A RX480 (~200€) with the rest of the computer consumes 240 watts and can "mine" 0.008 to 0.009 BTC per day.
If I went for an Antminer S7 (~350€) and underclocked it, I could of mined 0.00072117 BTC per day (1.6Th/s @ 400 watts).

I ended up spending less, using less power and getting more BTC per day.

i single readon can't mine 0.009 per day, that is insane i think you confused the amount, the return is 0.0015 per day

this is always better than 0.006 from an antminer that consume 1400watt, that is 4x one antminer s9 while consuming almost 1/10

i think it's better to wait for bitmain to release the new antminer s10 or s11 with better efficiency, i hope they make more model for lower consumption too
1325  Bitcoin / Bitcoin Discussion / Re: Bitcoin is useless or is it? on: May 15, 2017, 05:41:03 AM
If bitcoin is useless, then explain why literally billions of dollars are flowing into it.  The market determines the value. The market has spoken. You are wrong.

because the market don't care about the fee, the value you are seeing on the market is based on trading on exchange, which don't need to move any bitcoin, they are always there on the exchange and changed for fiat or changed back to bitcoin all the time

therefore it doesn't matter what fee there is they don't need to move their bitcoin too much, the fee will onyl prevent the so called average joe to use bitcoin, in the future if nop fix will be reached
1326  Bitcoin / Bitcoin Discussion / Re: WannaCry Ransomware Extorts 39 Payments Worth 6.49 BTC – TODAY on: May 15, 2017, 05:37:37 AM
Got that trash on my PC yesterday. I just laughed, did a full format and a quick reinstall of Windows. I strive to keep my PC as empty and free of important stuff as possible, and this finally paid off! I gotta say I'm kinda proud. Shame about my collection of porn though Sad

how did you get it? what you installed recently? so we can watch out better against this shit

In my country, two big hospitals have this virus, it's very disturbing. There is a suggestion that tomorrow does not directly turn on the PC, this is a recommendation from the government. The positive impact is that some people are curious about the BTC, but the negative impact of BTC impresses the currency used for crime. Hopefully, does not endanger the current BTC price.

This virus focuses on the server because most are still using windows 8 and below version, ordinary workers are accustomed to receive email every day so do not accidentally get this virus. It's disastrous and hard to decrypt manually if it's already infected. Hopefully the antivirus do their best in the next few days.

still not an excuse for those windows 8 user to not have a backup for sensible data like they have at their job, the first to do when you have something important is always a backup
1327  Bitcoin / Bitcoin Discussion / Re: Major burglary on: May 15, 2017, 05:32:06 AM


I wonder how many of the people who have had coins stolen from them are using Windows Operating System based computers?

Have any chromebook users, mac users, linux users had this issue?
Have any android or iphone users had this issue?


this is a common myth that linux is more secure when in the past there security holes for linux too, windows 7 i not so secure anymore, but windows 10 is a fortress it's very hard to infect if you are not stupid and install malware.exe on your computer

actually win 10 will stop you, recently i was going to run a miner(ccminer compiled by a newbie user) which was supsicious and win 10 stopped it before i can even attempt to do so, and it did not the same with the same malware compiled by a trusted dev

1329  Economy / Economics / Re: African country adopts Bitcoin as primary currency on: May 14, 2017, 07:18:33 AM
Bitcoin adoption by a country is not feasible currently
- The value fluctuates wildly. It is not possible for shopkeepers to update prices on an hourly basis.
- How would the government control money supply and banks?

At best, it can function as an alternate currency along with fiat.

as the OP mentioned they would need to buy huge amount in the first place to adopt bitcoi, this would make the value higher which would bring even more value to bitcoin due to panic buying

if then they were to issue those coins to their people through job, liek they do with fiat, i see no reason to believe that it won't work

the problem is that they first need a correct infrastructure to handle this, and without proper connection and security of their bank i see this an hard thing to do for a contry like that

another problem is that they need the fund at the beginning to buy all these coins to distribute to their citizens, and a poor africa country i doubt can have all these money...
1330  Bitcoin / Mining speculation / Re: Possible Mining Location. Abandoned Smelter! on: May 14, 2017, 07:05:02 AM
i don't think you can take and build your farm there, would be abusive in many country, i don't know how it work there but i suspcet it's the same

you can't make your a building which was abandoned pretty much like those abandoned house, i would check first if it can be used without issue by speaking with your boss

also is the 0.05 rate without tax or everything included? check this also, there may be a surprise there
1331  Bitcoin / Bitcoin Discussion / Re: WARNING:network under Massive spam attack. on: May 14, 2017, 06:57:53 AM
There are two types of spam txs.

The first is a block attack vector designed to bloat the chain with worthless
data. The 1MB Cap prevents that attack type. The fee market is the
mechanism that prevents this while allowing the network to remain
functioning with that 1 MB Cap.

The second is a fee attack vector designed to bloat the mempool and
increase the fee price. These automated scripts are specifically designed
to create different fee levels, in order to increase the priority fee price.
The lower priority txs will either take many hours to days to confirm or
be dropped after "72 hours". The purpose is to cause pressure for altcoins
that allow for new P&D schemes.

These two attack types can and will exist no matter what the Bitcoin
blocksize is, which is what Hydrogen was alluding to.

Only post worth reading in this entire thread.

The economics of the fee attack are obvious.  They do not need to spend that much money in order to get the fees to go up.  If they flood the lower fee levels with transactions they are paying smaller fees if the transactions do go through at all.   Also, due to their own attack their transactions spend a lot of time in the queue just clogging up the queue - less cost for the attacker.  If they are really successful then most of their spam transactions will never get into a block and will eventually get dropped.  The cost to the spammer of the transactions that get dropped is zero.

Just take a look at the chart here:

https://bitcoinfees.21.co/

Clog up the lower transaction levels and everyone who wants to actually do a transaction will have to pay more.

Larger blocks will not solve this, Segwit will not solve this, the actual solution is already in place:  pay a higher fee for your transactions if you want them to go through.



If everyone pays a higher fee then the fees will easily rise tenfold or more from their current level. There is a point where increased fees will only hold bitcoin back. Lightning network has the potential both for near unlimited transactions AND higher fees to miners.

In my opinion this is the best solution currently being offered to scaleability issues. And Segwit or larger blocks would solve this as it would make any spam attacks much more expensive to the attacker since they would need to clog up a larger number of transactions.

as i see it doesn't make sense for an attacker to spam the network with higher fee, which would cost him money just to increase the average fee for allt he other, unless this spammer is a miner of course which i suspect it could be

i also don't think that pying higher fee is a solution, that's the issue here, segwit would solve the second issue but not the first from what i can understand, i'm curious how they are "sending worthless data"

if by that he mean dust TX with no fee, these will simply be rejected
1332  Bitcoin / Bitcoin Discussion / Re: $0.85 transaction fee is absolutely ridiculous! on: May 14, 2017, 06:47:45 AM
If it costs you about $0.60 to send $170,000.00 to someone else, or anyone else, I'd say that's a pretty good deal. The problem is that it could cost you that same $0.60 to send $6 to someone too.

That's both the strength and weakness of bitcoin.

there should be a easily way to fix that, if perhpas they can add side priority to less valuable transaction, this would work not only based on size but ont he value that the transaction carry

the problem is that the fee right now is a fixed amount, this is where everything is wrong, should be done in a way that the fee is based on % of what you are sending and again not only on the size
1333  Bitcoin / Bitcoin Discussion / Re: RANSOMWARE impact on: May 14, 2017, 06:42:29 AM
I think the bitcoin will fall because of RANSOMWARE,it is impossible/Difficult to track who did this and in futur Bitcoins will be considered as a motivation mean for such act
It is not that difficult to track bitcoin transactions as you could see everything in the block chain and if the hackers try to send those coins then i am sure the authorities will be monitoring every move and they can easily track them if they plan on sending those coins to any exchanges and the coins will be blocked.

a somehow wise hacker would not send anything to an exchange, unless he can manage to mix the coins stolen properly, otherwise he would sell privately in real life, and would be impossible for anyone to track him

besides there is no connection between the address he used and his real identity, so the tracking would be pointless
1334  Bitcoin / Bitcoin Discussion / Re: Returning to bitcoin after 2 years! shocked at confirmation time! on: May 14, 2017, 06:05:26 AM
pay the correct fee, next time, i see that now if you pay half of the fee you can still have it confirmed in a good amount of time

... a spam of transactions at the moment.

What is a spam transaction?

anything that aim to increase the amount of transaction to a very high value in a short time frame, but really it subjective, there is now ay tot ell if soeone is spammign a tx or not, if he don't pay the fee it will be simply rejected

otherwise it will be accepted like many other transaction, int he end every transaction can be called a spam or not
1335  Bitcoin / Bitcoin Discussion / Re: RANSOMWARE impact on: May 14, 2017, 05:58:36 AM
the problem should not be tracking it, the problem is whoever is the moron that allow his/her computer to be infected

the security issue here have nothing to do with bitcoin but with the user, the last version of this malware is spreading through a security hole of windows, which was already patched by microsoft

many opf these infected people are still running old xp or win 7, which are more vulnerable, so again has nothing to do with bitcoin

1337  Economy / Speculation / Re: A price correction is happening now on: May 13, 2017, 06:32:47 AM
< $1000?

very unlikely, the price reocovered tot he previous high , which was around $1300, then from that we made a new high which is $1900 or something, i didn't check precisely

from this i can deduct, that the bottom will be the previous high, and will hardly fall under $1300, but i would also bet that below $1500 is a tough call, i would play the $1500-1900 range
1338  Economy / Economics / Re: What percentage of global population are using or have at least 1 satoshi? on: May 13, 2017, 06:27:26 AM
It's probably around %0.1 of the total population, I guess.

which make more sense now with this price grow and after all the japanese that are using it extensively, the rpeviously estimate was considered at least to be around 1M users and up to 3M

therefore having now 7M would be about right, surely this should match the price increase, if another spike will occur you know there are more new people buying
1339  Bitcoin / Bitcoin Discussion / Re: Losing Faith in Bitcoin? on: May 13, 2017, 05:55:33 AM
it's funny every time that bitcoin have a price correction, poeple suddenly think about a big crash and that bitcoin is died or other shit like that

i guess the more the value will big higher the more the fear will be to think bitcoin can go to zero and make you lose all your investment

this is the reason that makse them fear every minimal swings in the market, besides this i don't think the number of transactions being stuck have nothing to do with the value or we would sit below $1000 forever
1340  Bitcoin / Bitcoin Discussion / Re: What was the value of 1 Bitcoin when you first mined/purchased? on: May 13, 2017, 05:50:23 AM
i remeber was between $60 and $70, in may 2013 or april either one of these month, i mined 1 whole bitcoin with a single 7950, in one month

then i quickly sold it for $60 like a stupid, at that time i was very surprised that it was possible to generate money a gpu, one of my dream come true and because of that excitement i sold it immediately
