1301  Other / Beginners & Help / Re: How do I avoid and identify scams? on: July 15, 2023, 08:53:02 AM
For starters, what you would have to do is to study Bitcoin a bit and realize what makes it essentially different from the rest of the cryptocurrencies, which in the forum we usually call shitcoins. There are some less bad than others but they are shitcoins after all. Then you will realize that apart from some being pure scams, which are created as pump and dump schemes, the others are not worth it especially compared to Bitcoin.

A general rule to detect if an economic offer is a scam is that it has a too attractive profitability. In traditional assets, anyone who guarantees you more than a 10% annual return is probably trying to scam you, let alone if he offers you 50% per month and the like, as it is sometimes seen.

In the crypto world the returns are higher but there is no guarantee of anything and it is subject to extreme volatility.
1302  Economy / Micro Earnings / Re: freebitco.in 10000 roll script on: July 15, 2023, 04:38:29 AM
The probability of rolling a 10,000 is apparently 1 in 10,000.

It is actually half. It is 1 in 20,000. Apparently it should be 1 in 10,000 but the system is set up so that 00000 and 10000 are half as likely to appear as the rest.

I saw this explained quite some time ago in some thread and I am saying this from memory but I am pretty sure this is the case.

Apart from this, you have to count the variance. Even if you have a 1 in 20,000 chance of getting the 10000, if you have negative variance, you can play 100,000 rolls or more without getting it.
1303  Economy / Economics / Re: Biden's administration absorb students from loan debt. on: July 15, 2023, 04:32:30 AM
Well, I'm not surprised at the number of people in the thread saying it's good news, given the trend of this forum. Good thing there are those with knowledge:

Especially this part:

Quote
Age group   Amount owed   Number of borrowers
50 to 61   $282 billion   6.4 million
62 and older   $98 billion   2.4 million

This type of policy penalizes those who do well and rewards those who do poorly. Those who paid their student loans are now aggravated because Biden is going to pay for part of the party for the cicadas. In other words, two twin brothers studied the same degree and got into the same amount of debt. At the age of 60, one has long since paid off his student loans and has built up a good net worth, while the other has not only not paid off his student loans, but has many other loans because of his spending habits, among them regular parties with hookers and cocaine. But for the latter the state is coming to save him, lol.

Besides, without so much government intervention with student loans, college prices would not be so high and students would not need so many loans.
 
It is a typical example of politicians offering a bad solution to a problem that they have created and that only makes it worse.

This is nothing more than a campaign tactic for Biden seeing as it's election time.

Really? I would never have imagined it.  Grin
1304  Economy / Speculation / Re: BTC price hitting 30k twice this year. on: July 14, 2023, 03:52:32 AM
After a long wait for almost a year now the price can reach $ 31500, hopefully this will be a positive sign that the bull run will happen soon, I am optimistic that as long as there are no big cases like LUNA or FTX, investors will continue to buy because they already understand that when a halving day occurs, the price can up to 200% of the previous price.

Let's hope so. We are at 6-month highs, and seeing that the worst of the bear market is over and there is less and less time left for halving, what we would expect would be a sustained rise in price, although with ups and downs, until about $50K I would say, where I think there will be resistance. I think it is difficult for the price to go much higher than that mark before halving.
1305  Economy / Economics / Re: MicroStrategy Buys $250M in Bitcoin, Calling the Crypto ‘Superior to Cash’ on: July 14, 2023, 03:44:17 AM
Did I say I was never coming back to this thread?  Can't remember (liar!), don't care.

I'm bumpitty-bumping because I hadn't checked MSTR's stock price in a while but did so today.  I've got them and some other bitcoin-related stocks on my brokerage watchlist, like MARA, RIOT, and Coinbase.  And wow!  Bitcoin's price has been kind of stagnant and yet all of those stocks are booming.  Just for the record, here's an MSTR chart from May:



I don't see that graph as very different from the Bitcoin graph. Since May 1, the Bitcoin price had a slight sustained decline until about June 15 where it started to rise. Maybe the end of the chart is a little different, being the MSTR one more pronounced upwards, but if we take into account the leverage it uses to buy Bitcoin, it is to be expected.

And I've been following MSTR for a long time now, and it looks like they own so much bitcoin that their stock has become a proxy for bitcoin--who needs a BTC ETF when you've got Microstrategy, right?

An ETF will always be better than MSTR shares in terms of security, although in terms of potential return the shares can give you a better return because of the leverage. However, we must always bear in mind that leverage means risk and more leverage means more risk.

1306  Economy / Service Discussion / Re: Europe: The real Bitcoin and Blockchain superpower? on: July 14, 2023, 03:33:38 AM
I'm pretty sure the graphs lump UK with the rest of the EU countries despite Brexit happening a while ago.

Of course the graphs include the UK. They are talking about geographical Europe, not the European Union. If they include Turkey (as well as Norway or Switzerland) why shouldn't they include the UK?
1307  Bitcoin / Bitcoin Discussion / Re: is it Advisable joining Bitcoin signal group? on: July 14, 2023, 03:22:03 AM
...which resulted for many people to lose their money because of Crypto signal groups, were as they put almost all their money thinking the signal is a sure, little did they know they were making a terrible mistake.

...

So what do you guys think, let's share knowledge.

The problem is that people do not fully understand how to trade successfully, which generally involves a moderate return on capital. But if you invest $1K in trading, and expect to make $100K in less than a year, what you're going to do is lose the $1K in the blink of an eye. It doesn't matter if you join a Bitcoin signal group or what strategy you use.

If you are really curious, I would follow this advice:

Free signal group, you can join. If they later ask you to pay money or luring you to pay money, leave the group.
1308  Other / Meta / Re: [BAN APPEAL] UID: 1047338 / 2221175 on: July 14, 2023, 03:07:41 AM
Considering how many first offender accounts are still not banned, even if there's crystal clear evidence, like here, here or here, banning HedgeFX after his alt P2Pfinder got already banned, would be very inconsistent. Even first offenders don't get banned if there's crystal clear evidence.

Basically, P2Pfinder / HedgeFX got his initial punishment already by getting P2Pfinder banned and after that, HedgeFX learned from that mistake.

In my opinion, that is not consistent with the ban being to the person, not the account. That's why banned people are only allowed to create an alt to appeal their ban.

What do first time offender cases have to do with this one of someone who has already been banned?

In the case of this thread we are talking about a full member account, which at a good pace can take 4 months to return to that rank with a new account, so we could understand that he has received a temporary punishment of 4 months. However, following what you say, being banned would take no punishment, especially for low-ranked accounts. So a newbie or jr member who is banned, to escape the ban they would just have to create another account. What would be the punishment they would receive?
1309  Other / Meta / Re: Addition of more forum boards/sections and modifications. Any need currently? on: July 13, 2023, 02:10:26 PM
As I commented yesterday, I miss in the forum a board, or better a sub-board, of personal stories related to Bitcoin to collect all those stories we see in the forum about how cool Bitcoin is and how it has changed my life or the life of my friends/family/dog.

At least that threads like that could be moved there by moderation. I meant it in a joking tone, and I don't think it's a pressing need for the forum, but I think it wouldn't be a bad thing if it was created.
1310  Bitcoin / Bitcoin Technical Support / Re: Trying to understand double spending after 1 confirmation. on: July 13, 2023, 01:49:43 PM
You might also be interested to read this post, which describes how a miner can double spend a transaction with one confirmation: https://bitcointalk.org/index.php?topic=36788.msg463391#msg463391.

Nice read. I have taken the opportunity to read the thread as well, from twelve years ago. In the end, the conclusion I reach with this thread is the same as the one reached by a forum member in that thread. Basically that making such scam attempts could only cross the mind of a miner with large amounts:

I think it's more profitable to stay honest and rake in all those fees than try to spoof the block chain. Especially if it works and they get caught.Bitcoin will be declared worthless by the world.

And the one who answered him I think he was wrong:

For now. In future years, generation rates will become low and fees will remain meager. Alternative revenue models will become more attractive.

Apart from that:

The caveat being that the amount that you're depositing has to be more than your block reward at least for the attack to the worthwhile. Given how well the mining pools are connected to each other, it's unlikely that your block would be able to propagate faster than them so the scenario whereby your block gets stale is much more likely. The minimum cost for this attack would likely be more than the block reward, if you were to factor everything in.

It would also fail if the person receiving the funds sees the other block first with how the topology of Bitcoin network is designed. A more worthwhile attack would be the selfish mining, where an attacker tries to withhold and generate blocks faster than the rest.

I think that for a miner to think seriously about that nowadays it should be quite a bit more than block reward, I believe you here think in mathematics only.

If a miner can earn $170K or more by mining a block honestly, why would he try to scam someone for only $180K? That someone might later try to track him down to get revenge for the scam or be reported and wanted by the police.

With these considerations I conclude that this type of attempts, although possible, are quite improbable nowadays. In the thread cited by o_e_l_e_o perhaps the case that the OP tells is a case of this style, but the price at that time was like $1, and the block reward of 50 Bitcoins. It would be worth a dishonest miner's while to try for a few thousand dollars. Plus there were more individual miners, mining from a laptop from home, it wasn't as concentrated as it is now.

This is the reading I make, although obviously I am aware that I know much less about the subject than you do and I am open to your clarifications and corrections.
1311  Economy / Speculation / Re: Bitcoin to $120k next year - by Robert Kiyosaki on: July 13, 2023, 04:37:54 AM
Yes, well, it's one of the many predictions we're going to see, and in this case it's somewhat conservative I would say. Passing $100K after halving is what we all expect, I would say. Failure to complete the beating of that goal in this cycle will be a disaster for return expectations and predictive models will have to be rethought. Although it could also be that the peak is reached in 2025, according to previous cycles. I find the $120K prediction for 2024 OK, but I would expect the price to go up some more, surely to $150, and who knows if even approaching $200K but probably by 2025.

No, not really. Smiley
Accounts of any form and of any kind, are not considered as "valid collateral". We can say that are not even collateral...

OK, thanks for the info. I didn't know that.

No one has criticized you for being "aggressive" tagging newbies for asking for loans without collateral, as in the case of this thread?

Apparently not everyone agrees just like on accounts that are found to have been bought. I am in favor of red tag in these cases, both newbies trying to borrow without collateral and people buying accounts, especially if the purchase was after the introduction of the merit system.
1313  Other / Meta / Re: Why was this comment deleted? on: July 12, 2023, 03:01:11 PM
I can't see any reports on you directly but if you posted in a thread that was necro-bumped then your reply will likely have been deleted along with all the subsequent others who posted in it.

Could it be that it happened because he was citing a post that got deleted due to necro-bumping or some other reason? It sounds to me that if you completely quote a post that is deleted, it will be deleted too. Anyway, there are many posts after the July 2 necro-bumping still in the thread. You might want to check that as well.
1314  Bitcoin / Bitcoin Discussion / Re: My story about bitcoin and my old friend. on: July 12, 2023, 02:54:47 PM
So, no merits for the OP?  Grin Bitcointalk, you have changed.

In the end, these stories make me laugh. I have a mixture of tenderness and disbelief. I think a new section should be opened in the forum for personal stories, given the number of people who have stories to tell about how Bitcoin has changed their lives for the better.

Do you have the same story, I mean a close person, relative or friend who used to dislike bitcoin, and they became regretful after seeing a significant change after meeting again.
No, I haven't experienced such a situation.

In the end, it is that Well, it is that in reality, for buying and holding Bitcoin to change your life significantly, you would have to hold it for a long time without selling at the peaks, something that few people endure. If your personal situation only allows you to buy $50 in Bitcoin per month, after 5 years without selling you would have invested $3K and you would have the equivalent of $6K, which is not bad, but it does not change your life. To do so, you would have to hold out much longer or invest more, and if you can invest more, your economy is better and therefore the number to change your life must be proportionally higher as well.
1315  Bitcoin / Bitcoin Technical Support / Re: Trying to understand double spending after 1 confirmation. on: July 12, 2023, 02:40:27 PM
Sorry, edited my post a bit to reflect what I am talking about.
hashrate, you will always win.

Yeah, I have noticed that you have added two rather clarifying paragraphs.

My scenario describes a process where it can happen naturally (ie. occurs in a non-malicious intent). It has happened at least once: https://medium.com/deribitofficial/was-there-a-bitcoin-double-spend-on-jan-20-2021-45bdbd178c58.

Note that your number confirmation is in the perspective of which chain you're looking at. Hence, with the malicious intent, this is what an adversary would do given that he owns a significant portion of the hashrate...

In other words, in the scenario without malicious intent, it is rare that someone has actually attempted a double spend because it is extremely unlikely to happen and trying to guess when it might happen is like trying to guess the lottery numbers. Or even less likely.

*I mean the person has not tried to double spend. As said in the article:

Quote
We call this a double-spend not because a user has been double spent, but an input to the transaction has.

And the malicious case, I see it as a fairly high level of conspiracy in addition to having the luck that miner to mine the blocks he needs, so that probability is almost 0 as I see it and it would only be worth trying with large amounts of bitcoins. Even more difficult and unlikely with 2 or 3 confirmations.
1316  Bitcoin / Bitcoin Technical Support / Re: Trying to understand double spending after 1 confirmation. on: July 12, 2023, 02:17:32 PM
There is no such thing as a double spending with confirmation. At any point in time, each chain should not have a scenario whereby the same inputs are being spent twice because that would violate protocol rules. The so-called one confirmation double spending that you might encounter would be when a longer chain supersedes another, where a transaction would belong to a stale chain and thereby abandoned.

Well, I would like to try to understand it in a more practical way as follows: I am a miner, or whoever, and I want to try to scam someone with a transaction that is confirmed once. How could I do it? Does it make sense what I am saying?

It's just that it's clear to me how you can try to scam someone with an unconfirmed transaction, with RBF enabled, as I commented before, but not this.
1317  Bitcoin / Bitcoin Technical Support / Trying to understand double spending after 1 confirmation. on: July 12, 2023, 02:08:49 PM
The double spending thing is not new to me, I have a certain idea but one thing I read has made me think and look for information about it:

Is there anyone who has ever lost Bitcoins to a double spend attack after 1 confirmation?  Personally, I have never come across such a case.

With this thread I would like to raise doubts as well as expose what I think I understand because explaining also helps to learn.

The first type of double spending I believe has little to do with what the quote raises, as it does not involve any miners. It is simply someone who sends a transaction with RBF enabled as payment for a product or service but receives such product or service before the transaction is confirmed and what they do is send that amount of Bitcoin to another address with a higher fee.

Now let's move on to the hypothetical double spending that already involves some miner, in my opinion. I have searched a bit to see if there have been any cases of double spending after a confirmation and I haven't found anything either.

I don't quite understand how this could happen. In theory a miner should somehow mine an invalid block in which there would be a transaction or transactions that we could not consider valid as such?

It is clear to me that as more blocks are mined and in turn the previous blocks are reconfirmed, the probability of invalidation of the previous blocks increases, up to 6 confirmations, which are considered safe, leaving only the hypothetical case of the 51% attack as a threat, quite unlikely with Bitcoin.

Can you help me understand what a double spend transaction that has already been confirmed once would look like?

1318  Economy / Service Discussion / Re: Question from a newbie - raising $100 in BTC for charity on: July 11, 2023, 03:40:21 PM
You don't have to announce that you will donate your salary for charity or anything else. Announce it now is like you are fishing merit.

not only fishing merit but also trying to find employer or something related because of His promised good deed in which for me ? mostly are just a promises to be broken , why not  act accordingly and try to gain and help without telling others.

Like what said as quotation   "Let not the left hand learn about what good deeds of the right hand"

but all in all if this is true and legit then I hope that OP will find ways to make money and help others.

but he will never gain a single merit from me as it is an obvious merit fishing .

Well, I'm going to continue with my usual skepticism with this kind of threads, in this case more, since I donate every month more than the one-time amount that the OP wants to donate and I'm not opening threads because of it. I donate in fiat, but I have also made occasional donations in Bitcoin.

This smells bad to me, or merit fishing or something.
1319  Economy / Lending / Re: 250€ loan - Repay 300€ in 1 week on: July 11, 2023, 03:20:02 PM
I totally agree with this.
OP is best if you wait a week, then you can see if its any holes in your investment you gonna do, no need to rush it 7 days.

For me, a loan for such a short period of time makes me suspicious. Anyway I have seen that he has been red tagged for supposedly asking for the loan without collateral but he claimed to offer collateral, which for me is not clear which one. I guess condoras is fed up with seeing loan requests of the same style in this section.
1320  Economy / Economics / Re: Invest in Marketing on: July 11, 2023, 03:08:33 PM
If big companies like Google, Coca-Cola, Binance,  Pepsi,  and the rest still invest heavily in marketing,  then how much more you that is still a small business or brand operating on a street in your neighborhood,  or you with a laptop and a phone on your bedroom table?

Well, you talk about those brands but not the typical ones that are usually talked about saying that they don't need to run ads because their products sell themselves:

This Is Why You Will Never See A Ferrari Or Lamborghini Commercial On TV

Although it could be said that these brands and others use a marketing strategy, as for example Ferrari spends many millions in Formula 1, but of course it is essentially different.

You are right that nowadays you have to apply some kind of marketing, especially if you create a product or service from scratch, so the CAC is budgeted as an expense to be taken into account.
