Since when does ICE have any jurisdiction over MSBs? This is simply bureaucratic empire building.

Currency exchange on online forums shall also be identified as an illegal unlicensed money transfer service business by our friendly neighborhood tormentors hehehe.

You misinterpreted the quote.

which identifies ... independent cryptocurrency brokers’ use of ... online forums ... to engage in unlicensed money services businesses (MSB) activity.
2062  Economy / Speculation / Re: How will the Halving affect the BTC price? on: February 29, 2020, 10:11:35 PM
Well, basically block halving will affect miners financially.
Unfortunately, miners needs to upgrade their computer hardware such as GPU's for them to be able to solve blocks faster, since every halving, Bitcoin will become harder and harder to mine.
Eventually, some small time miners will shutdown due to the expenses in upgrading, electric consumption, and the continues halving of rewards.
Only those who have big mining farms is capable of sustaining their business.

You can't mine BTC profitably on a GPU or in your browser. The biggest factor in profitability is the cost of electricity. A small miner can make a good profit if they can get their electricity at a low cost.

So it's important to take care of miners profit.

The miners that are not profitable will stop mining, but mining will always be profitable to some miners. There is no danger of no miners being able to make a profit, no matter what the price is.

Well in order to be profitable miners should try mining rigs with low power consumption because it clearly depends on the Power consumption.

A miner's profitability depends on their costs compared to all other miners. That might be related to their power consumption, but not directly.

Could it be because the demands still the same while the supplies gets lesser and lesser?

The halving does not reduce the supply. It reduces the production. The supply does not get lesser and lesser. It continues to grow until it reaches 21 million.

This is what he apparently said, though I'm not positive where it was taken from. It looks like a Slack chat room.
Quote
“The first BTC seizure by courts will occur this year. Not with keys. By miners (nodes) acting to fulfill a court order. Without keys, BTC will be confiscated. Code is law, and courts can mandate patching code. Bitcoin is not encrypted. It is economic.”

Not exactly in line with the whitepaper, is it?

Not at all possible, either. Good luck with some UK court forcing half of the miners in the world to validate an invalid transaction and also getting all the nodes in the world to go along with it.
2064  Other / Beginners & Help / Re: Will the difficulty change and block halving take place on the same block? on: February 29, 2020, 04:58:51 PM
The difficulty changes every 2016 blocks. The halving occurs every 210000 blocks. To find when they coincide, you find the LCM ("least common multiple"). The LCM is 1260000. They will coincide every 1260000 blocks, or about every 24 years.

Will miners come together and roll back the blockchain? Craig Wright seems to think so, or is he spreading fud and lying again like usual?? i doubt that this will occur.

Do you have a source? I would like to see it for myself.
2067  Economy / Speculation / Re: How will the Halving affect the BTC price? on: February 29, 2020, 04:25:09 PM
According to the laws of demand and supply, the scarcity of the Bitcoin supply will lead to an increase in Bitcoin demand, leading to a rise in prices.

Scarcity does not lead to increased demand according to the laws of supply and demand.

There is also a small error in the article: the subsidy drops to 0 after the 33rd halving, not the 64th.

2069  Economy / Economics / Re: 542 ounces paper claims for every ounce of physical gold. on: February 26, 2020, 05:24:52 PM
I did some research and I found that there is some misinterpretation. The gold cover ratio is not a measure of leverage in any way. It is the ratio of the total value of the gold futures contracts on the exchange to the amount of deliverable physical gold held by the exchange. Without knowing how these contracts are settled and hedged it is difficult to gain any information or insight from this number.

Quote
There will almost always be more open interest outstanding contract gold then gold at COMEX warehouses simply because the vast majority of COMEX participants do not ask for delivery of gold and usually settle in cash or roll forward their contracts.

For comparison, consider CME Group's BTC futures. CME Group's Bitcoin futures open interest is 28160 BTC, yet they hold 0 deliverable BTC. The BTC cover ratio is infinity! That is not an issue or even remarkable because the contracts are settled in cash, and there is no need for the actual BTC.

Now, I agree that a ratio of 542:1 is unprecedented, but what it means going forward is not clear to anyone from what I can tell.
2070  Economy / Economics / Re: 542 ounces paper claims for every ounce of physical gold. on: February 26, 2020, 05:44:11 AM

Is the layman terms mean banker are shorting physical gold to the rate of 542x leverage??

Imagine gold market cap is $7 trillions
A simple math would come to the facts that:

542 * $7 trillions = $ 3,794 trillions

In layman term is rounding up to a whopping $4 quadrillions worth of printed dollar goes into shorting gold??
...

What is your source? I suspect that there is some misinterpretation going on here. In the last year, the price has risen 25%. If gold is really leveraged at 524x, then I think we would see borrowers going bust left and right. Also, if A loans B a ton of gold, and B loans C a ton of gold, and C loans A a ton of gold, then there is no actual leverage even though paper gold is 3x actual gold.
2071  Bitcoin / Development & Technical Discussion / Re: private key to public key generation bitcoin vb.net gives unknown error on: February 25, 2020, 08:39:11 PM
I'm trying to use secp256k1 eliptic curve to get the public key from private key but it gives me an unknown error error

Quote
Private Sub Button13_Click(sender As Object, e As EventArgs) Handles Button13.Click
    Dim private_key = "68040878110175628235481263019639686"
    'public key should be Nr6MbFUfMovKCX4vd5YpQnRYsN4rq6pNPEEBKmicAEwwuYLpJrt5LsRvfvR2G8pJ5rMchEMWDYJ7rdY GY7PjxHEa
    Dim public_key As String


    Using eliptic As New ECDsaCng()
        eliptic.HashAlgorithm = CngAlgorithm.ECDsaP256

        Dim data() As Byte = Encoding.UTF8.GetBytes(private_key)
        Dim key As Byte() = eliptic.SignData(data)
        public_key = key.ToString
    End Using

    TextBox15.Text = public_key
End Sub

I'm not an expert, but after looking at the docs (https://docs.microsoft.com/en-us/dotnet/api/system.security.cryptography.ecdsacng?view=netframework-4.8), I think I see several problems:

1. New ECDsaCng() initializes an instance with a random key pair.
2. ECDsaCng.SignData() does not return a public key. It signs a message. In this case it is signing the message "68040878110175628235481263019639686" ad returning the signatre.
3. Encoding.UTF8.GetBytes() does not covert a string to a number.
4. Byte.ToString() does not encode data using base-64

To extract the public key from ECDsaCng (once it is initialized correctly), I believe you can use ECDsaCng.Key.Export(). However, I can't figure out how to import the private key in the first place. Perhaps, ECDsaCng is not appropriate for what you are trying to do. Generating the public key is straightforward, but I don't know how to do it in .NET.
2072  Bitcoin / Bitcoin Discussion / Re: Crypto wallet explained simply. on: February 25, 2020, 08:11:49 PM
Some corrections and clarifications ...

The address are called public key like bank account number where you can send cryptocurrencies.
...
Crypto wallet also have private key, just like a password but different from a password because it gives you the full ownership of the wallet. Some wallet do not have this feature.

An "address" is not a "public key". An address is derived from its public key. A public key is derived from its "private key". A private key is generated from the wallet's "seed". A private key is not a password, though there are some similarities. A wallet can hold many addresses.

There are two types of crypto wallet:

1. The online/hot wallet
2. The offline/cold wallet

The online wallets are not safe and more susceptible to cyber attack. There are 3 types.
 

It is more complicated than that. A wallet can be ...
  • hot or cold (connected the internet or not).
  • custodial or non-custodial (not your keys, not your bitcoins).
  • hosted (accessed through a remote server) or local.
  • connected to the Bitcoin network with the ability to create transaction and maintain balances, or not.

Each one of these affect the security, convenience, and functionality of the wallet.

The Ledger Nano X is the one you can also connect with phone or also with laptop
The Ledger Nano S is the most common used

FTFY. Also, I believe that all hardware wallets can be accessed and controlled by compatible wallets on your desktop or mobile. I have several different hardware wallets and they all connect via USB to Mycellium and Electrum.

The aether, in addition to behaving as super-fine gas is under maximum compression and is incompressible thus, has the ridged properties of a liquid crystal.

A gas is compressible by definition. There is no such thing an incompressible gas.

If it is rigid, then it must have a high viscosity. If it has mass, then it must have inertia. If it has a charge, then we should be able to manipulate it. I don't think any of these properties have ever been demonstrated.

I remain unconvinced of the flat earth "buoyancy" theory of gravity because of the inconsistencies and contradictions, and because of the inability of proponents to explain it. I wonder if this one would be more suitable: Le Sage's theory of gravitation

...
The Coulomb force (electromagnetism) ultimately drives any material particles in motion. "Space and time" along with relativistic "gravity" is a concept from Relativity (1905) and was falsified by D&P Sagnac (1939) at the University of Paris. What was proven, is that there is a static aether.

I figured that Le Sage's theory might appeal to you because it describes something that is similar to buoyancy. Note that the theory does not depend on the existence of planets or space or relativity or aether.

My problem with your Coulomb force explanation (as I understand it) is that it requires an aether that has mass and charge. In addition, aether must be extremely rigid in order to transmit electromagnetic waves at high frequencies, but you write that it is a "super-fine gas", which is anything but rigid.

2077  Bitcoin / Bitcoin Discussion / Re: Bitcoin Halving: What is it? on: February 21, 2020, 04:19:16 PM
This basically means that the reward the miners will be reduced to 50% of what it used to be. So if today each miner receives 25 Bitcoins for solving a block, after the halving event he will receive only 12.5BTC. Following this math, the final number of Bitcoins will be roughly 21 million(20999999.9769 to be exact) in the  year 2140.For this statement i don’t understand, as halving should occurs unstoppable because numbers have ‘exponential function’ that means it infinite.. Not end in year 2140.

The smallest unit of bitcoins is a "satoshi", and there are 100000000 satoshis in a bitcoin. The protocol does not support fractions of a satoshi, so at a halving in the future, the subsidy go from 1 satoshi to 0 satoshis.

Some issues to consider:

1. How would the funds be administered? Who would decide how they are spent?
2. You are essentially proposing a 2% tax on everyone that uses the currency. Wouldn't people choose a different currency to avoid the tax?
