2881  Bitcoin / Press / Re: [2018-08-13]Study Finds Google Search can Forecast Bitcoin Price Rises on: August 15, 2018, 06:44:47 AM
I didn't read the report, but I'm skeptical.

Quote
It discovered that a standard deviation soar in searches for various keywords like "Bitcoin" predicted a small rise in the price of the token in the following weeks.

Averagely, according to the report, a single standard deviation shoot up in the keyword search result to a 2.75% price increment.

A 2.75% change is nothing. It can change by that amount every day.

When the price of a commodity drop with no reason, you should know that it is being manipulated.
It must be manipulation simply because you don't know why the price is dropping? That's ridiculous.  
Ok, markets normally react when something bad happens or if something bad is announced in the media.

The truth is that in a thinly-traded market, the price mostly goes up and down with no good explanation -- just random timing of trades.

You have been fooled by the mainstream financial press. Typically, the price changes and then the media has to say something. They come up with some seemingly plausible reason for the move and report it as fact.

The truth is that the news media's primary goal is to confirm your biases so that you continue to read their articles and generate ad revenue for them.

2883  Economy / Economics / Re: Bitcoin Manipulation Cartel — Price Suppression is their Goal on: August 14, 2018, 07:59:06 PM
They consist of CERTAIN Traders, Agencies, Big Financial institutions & Media (I can list many more but let’s keep it limited). They all work in a perfect synchronization to pull coordinated attacks to attain the goal of price-suppression.

Don't be stupid and expect everyone to just accept what you write.

If there is a cartel that consists of "CERTAIN" people, please list those "CERTAIN" people and provide the evidence that you have that shows that those "CERTAIN" people are working "in a perfect synchronization to pull coordinated attacks to attain the goal of price-suppression".

Otherwise, your are just spouting nonsense and there is no reason to believe anything that you say.

2886  Other / Beginners & Help / Re: my miner s9 found blocks did I get full reward on: August 09, 2018, 12:13:10 AM
Thank you very much for the explanation.
other question:
btw what the impact if the miner who found the block quiting mining for the pool before reach 100 plus blocks confirmation, is the block would staled / invalid?

The block reward is paid by a transaction in the block that is found (called the "coinbase" transaction), so it is immediate and permanent (unless the block is orphaned). The payment is made to an address supplied by the pool. Quitting mining after the block is published has no effect on anything.

Don't you think Bitcoin is a bit globalist? It is a one-world supra-national money system after all
Bitcoin is global, but not globalist. It doesn't demand the destruction of national sovereignty, and all of the other things that the globalists are creating.

Decentralization will destroy much of national sovereignty, and Bitcoin subverts a primary factor of control by a government over its people.

Most people need leaders, and personalities that can become rallying points. Donald Trump is a rallying point. Clinton, Obama, Blair Cameron and the like were not rallying points, they were strippers of national assets, and the promoters of global eugenics.

Becoming a rally point is one thing, but populism becomes dangerous when its power is then delegated to the rallying point.
2888  Other / Serious discussion / Re: Where does the "will" come? on: August 06, 2018, 04:40:04 AM
Schopenhauer referred to asceticism as the denial of the will to live.

The will to power ... is a prominent concept in the philosophy of Friedrich Nietzsche. The will to power describes what Nietzsche may have believed to be the main driving force in humans – achievement, ambition, and the striving to reach the highest possible position in life.

This should explain everything: What is margin trading?


The most important point is this: a newbie should avoid margin trading. It is very risky, and you are likely to lose everything.

It is easy to explain how hash rate is affected by price, but not so easy to explain how hash rate might affect price.
2891  Bitcoin / Development & Technical Discussion / Re: Explain SHA 256 Algorithm on: August 03, 2018, 10:09:43 PM
Hi all,

Can someone explain me SHA 256 step by step mathematical operation taking an example,i want to know each step from conversion of word to ASCII code and binary code ,later right shift and all those stuffs till i get a hash.

And i have another question why bitcoin uses double SHA256,and how does double SHA 256 compared to normal SHA256 exactly work?

I want to be a blockchain developer so i need to learn all these from scratch.

Thank you

I think this is what you are looking for: Mining Bitcoin with Pencil and Paper

This video is fun to watch too: https://www.youtube.com/watch?v=y3dqhixzGVo

The double hash is simply a hash of a hash of the data. It provides extra security in certain cases.

You don't need to know the details of the SHA-256 algorithm in order to use it. In fact, it is probably better that you not know it because if you know it, you might be tempted to implement it and make a mistake.
2892  Economy / Economics / Re: Why do older people like investing in Gold/Silver? on: August 03, 2018, 09:51:09 PM
One of the reasons why people like to invest in gold in my opinion:
because gold is free of tax and administration
Property, Vehicles, Bonds, Shares, Artworks, Bank Interests and others are subject to various taxes and routine administrative costs. The more assets you have, the higher your taxes and your costs. Not to mention the cost of care, depreciation of property values and unexpected costs. But not with Gold.
gold is free of those costs.

In the U.S., gains from selling gold are taxed at a higher rate than gains on other kinds of assets.
2893  Economy / Economics / Re: What happens if bitcoin price falls below the cost of mining it? on: August 03, 2018, 09:46:40 PM
"If Bitcoin prices drop below the cost of mining" miners just stop their operation and use the money they use for electricity to buy Bitcoin. Free market will be adjust according to the supply and demend. Nothing to be worry about to much.
That will be a huge mistake, I have seen people say that the bitcoin they mined back in the day when it was not profitable to do so was in fact the most profitable of all, the miners have a lot of money they are not going to suspend their operations just because it is not profitable at this time, since they know the price of bitcoin will recover and the bitcoin they get can be sold for a profit in the future.

Suppose your cost of mining is $6000 per bitcoin and the price of a bitcoins drops to $5000. Are you going to mine 1 BTC for $6000 or are you going to buy 1.2 BTC for $6000? A smart person would stop mining and buy the 1.2 BTC.
2894  Economy / Economics / Re: What happens if bitcoin price falls below the cost of mining it? on: August 02, 2018, 12:51:11 AM
I don't think it would really go lower than the price of mining, because the miners are going to be less likely to sell at a lost. It wouldn't make much sense to them. Mining factors into the whole supply and demand of crypto. Less miners willing to sell at a loss, then less Bitcoins available for sell, thus higher price.

That is a commonly stated misconception.

First, miners must sell most of their bitcoins, even at a loss, to pay for their operational costs: power, cooling, rent, labor, etc.

Second, when it comes to holding bitcoins, miners are no different than anyone else. They may or may not sell the bitcoins they hold at a loss.

Finally, miners are only a tiny part of the market. Miners sell only 1800 BTC of the 600,000 BTC traded every day. Their behavior has almost no effect on the price.

The reality is that if it costs a miner more to mine the bitcoins than to buy them, a rational miner will simply stop mining.
2895  Bitcoin / Development & Technical Discussion / Re: "Why blockchain needs cryptocurrency?" on: July 31, 2018, 09:12:17 PM
A generic block chain doesn't need to use a cryptocurrency because it is just a distributed database. Also, a cryptocurrency such as Bitcoin is implemented using a block chain, so the question kind of doesn't make sense.

Regardless, I think this is the answer you are looking for: A decentralized database that records exchanges of value, such as a public cryptocurrency block chain, requires the representation of the value to exist entirely in the block chain in order to ensure its integrity. If the representation were to exist outside of the block chain, then it would not be possible to guarantee that the block chain matches reality.
2896  Bitcoin / Press / Re: [2018-07-30] Romania Targets Cryptos With New Electronic Money Law, A Draft Bill on: July 31, 2018, 08:55:02 PM
Because of the decentralized nature of most cryptocurrencies, I don't see how a cryptocurrency-related firm could be considered to be an "issuer". Maybe it is an inaccuracy of the translation or an additional law-specific meaning of the word (similar to how a bitcoin trader is considered to be a money "transmitter" in the U.S.).
2897  Bitcoin / Press / Re: [2018-07-28] Giant Bitcoin Merchant Bank Posts Losses Over $130 Million on: July 31, 2018, 08:33:08 PM
They lost over $100 million trading? Why didn't they simply quit trading and wait for things to look up again? Blimey. I'd rather be paying my staff to play video games for a year or two rather than chase those losses until there's nothing left.

The article said there were $103 million in "trading" losses, but that $85 million of that were unrealized, which means only $18 million were actually due to trading, and $85 million were due to losses in the value of the bitcoins they hold. Those unrealized losses are real -- they directly affect the value of the company, but they are not a surprise and not necessarily an indication of poor management. Anyone who has held bitcoins since the beginning of the year has had similar results.
2898  Bitcoin / Bitcoin Discussion / Re: Diversification in cryptocurrency is a bad idea on: July 31, 2018, 08:04:53 PM
You showed the difficulties in diversifying between different coins, but you didn't explain why it is "bad". Done correctly, diversification is never bad.

If you want to diversify, you must choose non-correlated assets. Non-correlated coins do exist. Just look at the article's 2017 chart. BCH was not correlated with BTC, so diversifying into BCH was a good choice. This year, however, you will need to find other coins.

The article seems to say that you want a negative correlation in your investments. That is wrong. You want a correlation that is close to 0. A negative correlation may reduce risk, but it also reduces return. For example, the correlation between buying and short selling a single asset is -1. If you did both at the same time, your risk would be 0, but then your return would also be 0 (ignoring fees).
2899  Bitcoin / Bitcoin Discussion / Re: Poll reveals that 75% of the US investors believe bitcoin is 'very risky' on: July 31, 2018, 07:46:26 PM
Everyone knows well that bitcoin is a risky investment and there is no need to conduct a survey for knowing this.

Apparently, everyone doesn't know. Only 75% said it was risky.

I feel sorry for the other 25%. Because of their ignorance, they are going to end up with nothing, regardless of what happens to Bitcoin.
