21  Economy / Trading Discussion / Re: Newbie in crypto trading, whelp! Bot or human? on: April 18, 2018, 11:32:35 AM
If you can't afford the loss of your investment, it's best not to choose between the two. Human and bot are not much different. The bull market will make money, and the bear market will lose money.
When you have limited funds, choose some activities that are more suitable for you. For example, you can participate in some activities of the forum and accumulate more original funds.
22  Bitcoin / Development & Technical Discussion / Re: Dormant Bitcoin Address Mining Homemade Way on: April 18, 2018, 10:05:09 AM
I think the focus of your idea should be how to generate the address you want to scan.
Believe me, it doesn't make much sense to scan a library generating from number or a downloading library, because countless people have already done the same thing.
Again, completely random generation does not make much sense, because the sample library is too large.
You should plan your ideas carefully. If you have a creative idea, it makes sense to practice it.
23  Bitcoin / Development & Technical Discussion / Re: wallet.dat encrypt by multiple users question on: April 18, 2018, 08:41:56 AM
If I give over my wallet.dat file to another guy.

Then he and me can use from same wallet. First users can use balance at that usage time, right?

Then what happen if one user encrypt it?

Other user can't use? First person who do encryption wins? Because he only know password?
Obviously, one person's encryption can't affect the use of another person.
Bitcoin determines ownership through a private key. You give the wallet to another person. The other party already knows your private key and can transfer your funds.
You are now encrypting the private key. When you use it, you still need to decrypt the private key. So your encryption has absolutely no effect on other people who already know your private key.
Remember: Don't give your private key to anyone.
24  Bitcoin / Development & Technical Discussion / Re: How to import account balance to an excel sheet on: April 18, 2018, 08:22:52 AM
If I give only view permissions and enter it to excel only, I don`t think there`ll be a security issue with the url

I just figured out this https://api.binance.com/api/v3/account?key=9Z42ubqjCJbwXAKlncofGp8LHmJThdJrBb34rwefd23 link gives a weird error message. I feel like I`m pretty close to the solution. Do you have any advices?
That one particular endpoint is listed as being a "GET" request, so will work by just creating a basic URL... however "account" is a USER_DATA endpoint, which is a SIGNED endpoint, which:
... require an additional parameter, signature, to be sent in the query string or request body.

So you need to calculate the appropriate HMAC-SHA256 signature for your request, as per:
- Endpoints use HMAC SHA256 signatures. The HMAC SHA256 signature is a keyed HMAC SHA256 operation. Use your secretKey as the key and totalParams as the value for the HMAC operation.
- The signature is not case sensitive.
- totalParams is defined as the query string concatenated with the request body.

And attach that to your GET request...
Code:
https://api.binance.com/api/v3/account?key=9Z42ubqjCJbwXAKlncofGp8LHmJThdJrBb34rwefd23&signature=YOUR_HMAC_SHA256_SIGNATURE_GOES_HERE&timestamp=MILLISECOND_TIMESTAMP_OF_REQUEST

Check the examples: https://github.com/binance-exchange/binance-official-api-docs/blob/master/rest-api.md#example-1-as-a-query-string

I'm not sure you can use "key" in the query string tho... the examples all seem to indicate that it needs to be sent as:
API-keys are passed into the Rest API via the X-MBX-APIKEY header.

I don`t know how to calculate HMAC SHA256 and implement it. Can you teach me that please?
Also if you think you can give a complete example of a URL that I could just replace the keys in, that would be the best

I agree that "key" part doesn`t really work. Because I get the same error when I just write https://api.binance.com/api/v3/account
In java, you can call an external library directly which is
Code:
import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec
My source code like this:
Code:
Mac sha256_HMAC = Mac.getInstance("HmacSHA256");
SecretKeySpec secret_key = new SecretKeySpec(secret_Key.getBytes(), "HmacSHA256");
sha256_HMAC.init(secret_key);
String hash = Hex.encodeHexString(sha256_HMAC.doFinal(message.getBytes())).toUpperCase();
return hash;

You don't need to learn how to calculate HMAC SHA256, which is repeated inventing the wheel.
You need to find source code for calculations based on your programming language, such as python or java, and use them directly.
According to my own experience, I am a java programmer. After I found the code of HMAC SHA256, I saved it as a static class and then call it every time.
26  Economy / Economics / Re: 99% of the people still think that fiat money are better than crypto on: April 18, 2018, 07:41:48 AM
That's great. Let's do an arithmetic problem.
There are 150-250 types of currencies in the world. Let's take 200.
On average, the average supporter for each currency is about 0.5%.
According to what you describe, 99% people think fiat money are better than bitcoin, then 1% think bitcoin is better than fiat currency. I think this is really great news for bitcoin.
27  Economy / Marketplace / Re: Do you have an idea to invest your bitcoin in offline business? on: April 18, 2018, 07:27:42 AM
Used in offline business, why must we use bitcoin investment? Isn't it easier to change bitcoin to fiat currency in the market? Or do you use bitcoin to pay your employees?
I believe that 99% of employers will not choose to do this because you have to teach your staff to use bitcoin wallets, which will increase the difficulty of tax filing. Bitcoin was born for online business, and it doesn't have to be fantasy that it fits into any scene.
28  Economy / Speculation / Re: The future price of bitcoin? on: April 18, 2018, 07:21:42 AM
As for the future price of Bitcoin, I can't give you a specific price, but I think a more reliable way is to calculate inflation in the world. Based on this value, it would be more appropriate to estimate Bitcoin's price.
For now, I personally think that Bitcoin's price base is 10,000 USD. Below this price, I think bitcoin is underestimated. Above this price, you can sell it temporarily.
29  Economy / Economics / Re: Crypto is more like “a psychological experiment than a serious investment" on: April 18, 2018, 07:15:33 AM
Those who said these things certainly did not invest in Bitcoin. Lol
As for Bitcoin's bubble, then take the example of a tulip. Anyway, I haven't seen the tulip bubble. I have only seen fiat currency bubble for decades.
As for economics, I believe that Bitcoin is very much in line with F A Hayek's ideal currency. Although Robert Shiller is also a well-known economist, Bitcoin is not merely an economic issue. It also involves politics. I think that considering it only from the perspective of economics is relatively narrow.
30  Bitcoin / Bitcoin Discussion / Re: Why people attract for the BitCoin than other crypto currency? on: April 18, 2018, 06:30:32 AM
Because Bitcoin is the first one. This is the so-called first-mover advantage.
Perhaps other currencies have one or the other advantages, but Bitcoin is the first known virtual currency. Countless legends take place in the history of Bitcoin.
Most of the public do not understand technology, but they are not stupid. The value of money does not come from technology, but comes from consensus.
31  Bitcoin / Bitcoin Discussion / Re: Serious accusation on Roger Ver about co-opting a blockchain event in Tokyo on: April 18, 2018, 06:18:49 AM
it does not matter. In the history of Bitcoin, Roger Ver is only a minor person. To a certain extent, Satoshi Nakamoto is also the same. Decentralization is the consensus foundation of virtual currency. Why do you care about the whereabouts of one or two so-called celebrities?
As for Bcash, as a Chinese, I know the Chinese best. I currently own Bitcoin, I will always have Bitcoin, but I will not hold any Bcash.
32  Bitcoin / Bitcoin Discussion / Re: Is there any way for Bitcoin users to be protected by governments? on: April 17, 2018, 06:44:59 AM
The simpler method is to sell Bitcoin in the market, and then take your money to buy a house. Is fiat currency not equivalent to an intermediary here? You use Bitcoin to buy a house. If there is a dispute, you have to prove that you paid for Bitcoin and the value of Bitcoin paid is measurable. This is actually a very troublesome thing. So there is no need to think that Bitcoin can be used on any occasion.
33  Economy / Speculation / Re: Another reason for Bitcoin price high on: April 17, 2018, 06:36:56 AM
I always thought this was April Fool's Day news. But Bitcoin fell from 19,000 to 6,000, and now it has risen to 8,000. Overall, I think it is in a relatively low position. However, if you are a Bitcoin supporter, you don't have to be too serious about the news. Bitcoin's value comes from consensus, not from a specific group of people.
34  Bitcoin / Bitcoin Discussion / Re: Ponzi / Pyramid Scheme / Bubble on: April 17, 2018, 06:21:07 AM
When it comes to bubbles, the biggest bubble should be fiat currency. The issuance of currencies such as the United States dollar and the euro is more restrained and still better. If you can find China's M2 data, it will definitely surprise you. To some extent, this is why Bitcoin is popular in China and explains why the Chinese government closed the Bitcoin exchanges.
35  Bitcoin / Bitcoin Discussion / Re: Bitcoin as money on: April 17, 2018, 05:50:40 AM
There is no doubt that Bitcoin is the money of the future. But money has a lot of features, not just for shopping. For example, if a Chinese holds US dollar cash, he cannot use US dollar cash to purchase goods directly in China, but instead uses the dollar's hedging function. Many people are concerned about whether Bitcoin can achieve the function of buying coffee on the street. I think this is the most insignificant way to use it. It's like using a supercomputer to calculate high school mathematics.
36  Bitcoin / Bitcoin Technical Support / Re: Assistance Sought on: April 16, 2018, 10:13:47 AM
I am from India & have approximately 3 bitcoins. These coins are stored in my hard drive & I do not know as to how to encash the same. These coins were given to me in lieu of consultancy I had rendered to a client. He has I need to decrypt the same & I have no clue as to how to go about it ? Can anyone pl help ? Tx n with best rgds
what kind of consultancy?
if it was about bitcoin and/or cryptocurrency, wouldn't it be ironic you are asking this?
or your payment would be part of whatever inside that thing you need  to decrypt?

How Stored :- Not Known
Source of transfer :- IRC
Bitcoin Address :- No
Wallet.dat file :- No
S/w used :- Bitcoin Core

Pl Note :- I was asked to install a software which turned a normal hard drive to a nano ledger s. When I log on to linux (debian) the same reads as ext4. The hard drive works perfect & there are no malwares / virus in the hard drive. Consultancy fees will be transferred on successful completion.
how could you say (know) you have 3 BTC but don't have a bitcoin address as reference?
you mentioned "Bitcoin Core" but then you were asked to do something related to a nano ledger s?
no consistency and none of his info make sense, he should start over telling the story from the beginning with simple words

I have a feeling this is another variation thread of "Please help decrypting my wallet and I will pay handsomely"

Thank all for the help (guidance) . After connecting the raspberry to the HDD I have found the WALLET.dat , it was hidden in the folder
WALLET ID.
Congratulations, you basically got your Bitcoin. However, I suggest that Bitcoin forked a large number of coins last year, such as BCH and BTG. After you get your Bitcoin and sell them, you can use this file to claim many forks. Although they are not big money, they are worth mentioning.
37  Economy / Trading Discussion / Re: Margin : Never try on: April 16, 2018, 09:56:41 AM
I can't agree with you. The margin is very helpful at some point. For the simplest example, in some moments where the market is extremely volatile, you need to trade to make a profit, but often your funds are not in the right place. Using margin at this time allows you to lock in profits, and then you can calmly mobilize funds to fill margin.
Margin is an effective financial tool, and the tool is neutral. You think that margin is not for you and it is dangerous. There is no problem. But if you think that margin is not suitable for everyone. It is wrong.
38  Economy / Trading Discussion / Re: Do you encourage friends and family to invest in crypto? on: April 16, 2018, 09:45:53 AM
no way. Because the reason is very simple, when they make money, they think that they have made the right choice; when they lose money, they will think that it is your fault. Investment is a very private matter, so it's best not to share it with others. Because everyone's personality and patience are different, Bitcoin may not be suitable for everyone.
If you are really confident in your investment, you can use a more conservative approach and let them entrust you with money. You can pay them interest.
39  Economy / Speculation / Re: People panics because the price goes down. on: April 16, 2018, 04:44:42 AM
This is normal. The timing of entering the market is very important,  you enter at the price of 3,000 or 19,000, the difference is great. Unfortunately, most people will choose high points for entering.
40  Bitcoin / Bitcoin Discussion / Re: Should I sell house to buy bitcoin if it drops below $ 5000? on: April 16, 2018, 04:22:12 AM
This sounds crazy. But maybe crazy people can make big money.
I don't know if you're doing it right, but I have a family. I don't have the courage to be all-in.
So,good luck.
