I think that there are two major questions left to answer:
Actually the more important question is not about any of that, it is all about the price of bitcoin. ...

Price only matters as long as there is a subsidy. I assume that when we talk about long-term, we are talking about post-subsidy.
1562  Bitcoin / Development & Technical Discussion / Re: On bitcoin's very long term future without miner rewards on: January 07, 2021, 07:55:22 AM
21 million coins won't be the final limit. Majority will eventually agree to keep btc block rewards at a sustainable level.

What do you mean by "sustainable"? How do you determine what is sustainable, and how do you know that fees won't provide it?

I sincerely believe we can anticipate a chain-split revolving around this issue come early/mid 2030's; One side would stick to the supply cap and the other side would eliminate all remaining halvings

Why would there be a split? I don't think there is enough information to justify either side at this point, and it might become clear which way is better as more information is gained. For now, your prediction is based on nothing.

I think that there are two major questions left to answer:

1. What is the optimal maximum block size?
2. Will fees alone be enough to secure Bitcoin?

I don't think that anyone knows the answers to those questions yet.

Regarding the optimal block size, I think that there needs to be a way to incentivize miners to reach an equilibrium. Technocrats dictating a policy is the absolute worst way to approach it. An unlimited block size might be the answer, but I suspect that it would not as it would turn into tragedy-of-the-commons problem.

Regarding security through fees alone, there is no way to know if fees are enough without knowing what amount of fees are necessary to secure the block chain, how much people will be willing to pay, and how big the blocks will be.
1563  Bitcoin / Bitcoin Discussion / Why did I receive 547 satoshis? on: January 06, 2021, 11:30:54 PM
[snip]

No need for another post. Here are some others to read instead:

You are not the only one here, there many other people receiving a few amount of satoshis into their wallets for no reason. After a quick research, I saw mostly high rank and old forum members are receiving these satoshis. Here is another forum member talking about this case: https://bitcointalk.org/index.php?topic=5275441.0
I would suggest you to read this topic here (https://bitcointalk.org/index.php?topic=5175238.0) by @fillippone, where he explained about dust attack.

Here is a guide showing how to dump the 547 satoshis if you use Electrum: https://gist.github.com/ncstdc/90fe6209a0b3ae815a6eaa2aef53524c

Hi there!
I think my old computer has some BTC in it but it's an REALLY old computer (since 2009 I think),
what's the most useful - risk free way to check if I do have any bitcoins in it?
It wont start, I mean it does but crashes

In summary,
1. Look for the file "wallet.dat". Make a copy and keep it safe and do not share with anyone (in case it is not encrypted).
2. Install bitcoin core on a new computer. Replace the new wallet.dat with the recovered wallet.dat. Let it synch (or re-scan if already synched).
1565  Bitcoin / Bitcoin Technical Support / Re: Tx Id 0/unconfirmed, not in memory pool 2 years ago... on: January 06, 2021, 04:59:34 AM
Help - I am the recipient of a transfer that was never received from 2 years ago. It shows incoming to my Bitcoin Core Wallet but status is 0/unconfirmed and not in memory pool. The tx id does not show up on blockchain and other sites as if it does not exist. But again it shows incoming, is it possible sender sent transaction then double spent or completely low balled fee to void transaction? Wouldn't that still show a record of txid?? I have also been researching CPFP but cant figure out how to execute it in BC. Any ideas or Help would be greatly appreciated!

With a little work, you figure out what happened to the bitcoins that you were supposed to receive.

Look at the inputs of the transaction. There will be addresses and amounts, or (even better) transactions and indexes. Look up those addresses or transactions in a block explorer to see where the bitcoins that were supposed to be sent to you actually went. If the coins were sent somewhere else, then you probably won't be able to find out where, but you can find out when.
1566  Bitcoin / Bitcoin Discussion / Re: Satoshi female or men ? on: January 06, 2021, 04:34:51 AM
Until such time I found the Binance Blog that it is impossible from a characteristic of a woman become a crypto enthusiast.

Let me elaborate you on what content in the article in some important points and reason why women aren't in crypto and Satoshi isn't a female in gender.
  • Women are not interested in blockchain and cryptocurrency
  • Women are not skilled in investing in crypto
  • Blockchain companies are not women-friendly
  • Women don't occupy top positions in blockchain
  • Women cannot contribute to blockchain development

Not only are none of those true, but the article you links says they are not true.

You are not an idiot because you misread the article (maybe your English skills aren't very good), but you are an idiot because you believe that those statements are true.
1567  Other / Serious discussion / Re: California Court of Appeal / Coinbase: not your keys, not your (forked) coins? on: January 06, 2021, 04:22:06 AM
Forked coins are "third-party" coins even if they're forked from supported coins, and the exchange has no obligation to install its software or to provide services related to these third-party coins, if this is not marked in the User Agreement. The exchange has therefore no obligation to make forked coins available to its users.
Honestly, as much as I hate Coinbase, this makes sense. There are a sh*tton of forks (I believe the website isn't even up to date) and if I owned Coinbase, I'd do either the same or allow the customer to take the forks with a little premium for my company's efforts of retrieving them (unless I directly gave the customer their privkeys).


I don't like this slippery slope argument. Sure, there are a lot of forked coins, but we can be reasonable here. Some exchanges refused to credit their users with BSV. BSV is #14 in market cap. This is significant. Just because you allow a user to use their #14 ranked coin does not mean you need to give them access to #1,400. I am not opposed to a reasonable handling fee by the exchange that covers the costs associated with crediting their users the coins from the split.

I think the exchange is being reasonable. They don't write that they are not going to support any forked coins, only that they are under no obligation. What would you rather they do? They can't make a list of future forks. They can't support all forks. So, the reasonable action is to decide on a case-by-case basis, which is exactly what they do.

If a customer wants forked coins or air-drops that the exchange won't support, then it is easy enough to withdraw the bitcoins to a wallet, receive the forked or air-dropped coins, and then put the bitcoins back.

Usa will find new dollar backer
If not whole usa dollar will crash down but bidden will do it
Good backer better then gold or oil
With this new backer usa dollar will go strong

The dollar will never be backed by anything ever again. You can't put the djinn back in its bottle. The junkies need their fix.

The dollar is backed by the full faith and credit of the US government. It's always worked because the US has never defaulted on its debt. It'll work until the US defaults on its debt or until people believe that the US can not service the debt. At the rate that it's growing the debt, that may be sooner than later.

A lot of people say that, but it is nonsense. The U.S. will always be able to pay its debt and it will never default because it can print as many dollars as it needs, but at some point those dollars will be nearly worthless.
1570  Bitcoin / Legal / Re: BTC taxes - Unknown cost basis on: January 03, 2021, 06:59:03 AM
Thanks all for the answers!

It is definitely a significant amount of money, so I am really concerned about doing things right from the beginning! I don't think I want to declare it as "other income", not to run into the risk of raising suspects about it being dirty money (this is also true when moving a large sum from an exchange to my local bank account I guess). And I am totally OK with paying taxes on the whole sum ($0 cost basis), as it won't significantly affect taxes in my case.

I would assume that not all tax advisors are equally qualified on this specific topic: are there any sufficiently experienced that somebody can suggest?

It is long-term capital gains. It's not complicated, even if you don't have any documentation for when you acquired them. Any CPA should be able to deal with it.
1571  Bitcoin / Development & Technical Discussion / Re: What is technical c++ term for {0} in this: int nHeight{0}; ? on: January 02, 2021, 01:44:46 AM
Old code:  Array { 1,2,3,4,5 }
New code: Array { { 1,2,3,4,5 } }

Every C/C++ compiler before 2011:
Code: Array = { 1, 2, 3, 4, 5 }

After 2011:
Old code:  Array = { 1,2,3,4,5 } // this still works
and
Array{ {1, 2, 3, 4, 5} }

None of those are examples of actual code, so it is impossible to comment on what is syntactically correct and what isn't.

You are out of luck. Finding the passphrase won't help if you don't have the wallet data or a backup, and an address will not help at all.
1573  Bitcoin / Bitcoin Discussion / Re: Bitcoin Electricity Consumption on: December 30, 2020, 10:51:44 PM
I think CO2 has been commandeered as the go to metric for environmental impact because it occurs in a wide range of scaled processes. But it does paint a really incomplete picture of the situation. Perhaps a more holistic indicator could be something like environmental entropy production. Some metric that describes the rate of environmental disordering, which stresses the regulatory mechanisms that exist in our environmental ecosystem (e.g. CO2 absorption and transformation or pollinator populations that sustain flora populations).

So lets just use "impact" as a general term for human activity disordering the environmental state. Whilst the Bitcoin consumes electricity, it provides a valuable service. That is the security consensus of the PoW method which is enforced by thermodynamics. Some form of environmental impact in the form of electricity consumption, hardware manufacturing, etc. is of course acceptable. The amount of impact should be equal to the intrinsic value of processes that Bitcoin is used for (currently speculative, but the implementation horizon is fast approaching).

I don't think that many people use CO2 as a measure of overall environmental impact. Rather, it is a measure relating directly to global warming. There are other factors in global warming and they can also be measured and acted on.

I think that environmental entropy production is far too abstract to be measured. How would you measure that quantity? If you can't measure it, then you can't really act on it.
1574  Bitcoin / Legal / Re: Donating Bitcoin and IRS form 8283 on: December 30, 2020, 07:57:38 PM
$120 for a single donation (https://cryptoappraisers.com) isn't ridiculous---that's significantly less than 1 hour of billed time from a competent CPA. considering you're avoiding any capital gains taxes and also deducting the entire amount of the donation, $120 seems like an afterthought, especially if you're donating higher amounts.
gifting long term capital gain property = extremely lucrative tax breaks. if they just allowed large untaxed noncash donations without any documentation, that could be abused left and right, so they put the onus on the taxpayer to prove it.
While $120 won't break the bank, it is still ridiculous. It is a rent-seeking rate. The appraiser benefits from the regulation rather than any skill or expertise that they might have. You don't need an hour of a competent CPA's time to look up the price on coinmarketcap. Furthermore, a self-reported value cannot be abused because the IRS can easily check it.
i agree, and i reckon that's why there is an exemption for publicly listed securities. the regs obviously weren't written with bitcoin in mind. i'd like to think that exemption will eventually be expanded to include cryptocurrencies, though i wouldn't hold my breath.
considering the detail required on form 8283 and the legal liability they are taking on, i'm curious---what do you think a fair price would be?
All they would have to do to fix it would be to extend the regulation from security to any property traded in a regulated market. There is no good reason for restricting it to a security.

If we assume that an independent appraisal is necessary, I think a fee similar to what is charged by a notary would be reasonable since the activity is similar. Notaries charge between $2 and $20.

1576  Bitcoin / Legal / Re: Donating Bitcoin and IRS form 8283 on: December 29, 2020, 06:02:01 PM
I've done this.  You need an appraiser. E.g. https://cryptoappraisers.com/  (like ... maybe you can get away without one, but that seems ill advised.)

You can do it somewhat more efficiently if you're going to make many donations to do a large amount at once to a Donor Advised fund, e.g. Fidelity Chartable and then make further donations out of the trust-- because then you just have a single bitcoin donation.

It's also advantageous to make a larger amount of donations in the same tax year because you can't write off the donation while using the (now pretty large) standard deduction-- so it's better to donate all at once in one year, don't use the standard deduction in that year, and then in other years continue to use the standard deduction.

Thanks, Greg. That is helpful.

I was hoping to do it this year (meaning this week), but it looks I'm going to be too late because of the complexity of the process. Also, it really bothers me that the IRS requires me to pay someone a ridiculous amount of money to say that the donation is worth $X in their expert opinion, when all they did was copy down a number from coinmarketcap.

*not tax advice*
I understand that the appraised fair market value would be the price of bitcoin times the number of bitcoin you are donating.
My advice would be to contract with a tax professional who is familiar with your individual tax situation to help you fill out this form.

If it were only that simple ...

Quote
Part I, Information on Donated Property

You must get a written appraisal from a qualified appraiser before completing Part I.

...

Part III, Declaration of Appraiser

If you had to get an appraisal, you must get it from a qualified appraiser. A qualified appraiser is an individual who meets all the following requirements as of the date the individual completes and signs the appraisal.
1. The individual either:
  a. Has earned a recognized appraiser designation from a generally recognized professional appraiser organization for demonstrated competency in valuing the type of property being appraised, or
  b. Has met certain minimum education requirements and has two or more years of experience in valuing the type of property being appraised. To meet the minimum education requirements the individual must have successfully completed professional or college-level coursework in valuing the type of property obtained from:
    i. a professional or college-level educational organization,
    ii. a generally recognized professional trade or appraiser organization that regularly offers educational programs, or
    iii. an employer as part of an employee apprenticeship or education program similar to professional or college-level courses.
2. The individual regularly prepares appraisals for which he or she is paid.
3. The appraiser makes a declaration in the appraisal that, because of his or her experience and education, he or she is qualified to make appraisals of the type of property being valued.
In addition, the appraiser must complete Part III of Form 8283. See section 170(f)(11)(E) and Regulations section 1.170A-16(d)(4) for details. ...

Firstly i am not american netizen but im curious about this so in there when you want to donate you should fill out form  Huh why you just deposited into their address anonymously just tell the charity owner

Donations to charities reduce your income tax in the U.S., so I can give more -- basically the amount plus all the taxes I would have had to pay.

For example,

Selling $5000 worth of bitcoins would cost me $500 in taxes, so only $4500 would be left for the charity. On the other hand, giving $6667 worth of bitcoins and deducting the donation from my income would save me $1667 in taxes, so my cost is still $5000. The difference is that all the money goes to the charity and none goes to the IRS.
1580  Bitcoin / Bitcoin Discussion / Re: It is pointless if the BTC fees increases along with rise in BTC price! on: December 27, 2020, 08:44:08 AM
I have observed many times whenever there is rise in the price it will proportionally increase the fees as well.

The price rises as more people use Bitcoin. The fees rise as more people use Bitcoin. The price does not cause the fees to rise, but they are related, as you can see.

Also, sometimes when there is a quick rise in price, people flood the block chain with transactions, presumably moving coins in and out of exchanges. This causes the fees to rise temporarily.
