1  Bitcoin / Bitcoin Discussion / Re: Why was is it necessary to create digital signatures on: December 04, 2025, 07:30:35 AM
Hi guys, I was trying to understand why it was necessary to bring up the idea of digital signatures. since we have the public key and private key that  can actually prove that we own that particular address. I couldn’t get a convincing Answer that’s the reason I created this thread. I hope get someone to help me out and explain to me why it was necessary to come up with  that in a simplified context please.
When you go to a physical bank, one of the ways of proving that you are the owner of the money in the account is signing your signature. You dont give people the password to your account for them to be sure that you own the money inside.

This post would help.
A signed message proves that you're the owner of a public key, because the only way to sign a message of a public key is to own its private key. This is how coin ownership is retained without disclosing the private key. You simply sign a message that says what you want to spend etc.

Signing a message shouldn't be a trouble, but after reading the reddit post, I wouldn't feel as comfortable as I do with Bitcoin signed messages. I have no idea how Ethereum works, but as it turns out from the first reply, signing transaction hash can grant ETH ownership. Signing a simple "hi, this is <date>" would never harm you in Bitcoin, but I wouldn't cross my fingers it will neither harm in crazy-Etherland.

I dont know which country you are from but when we go to the bank the way they verify your is you need to take out your bank card and authenticate with your PIN number and/or they will ask for ID. They will never just ask you to sign something because they don't know what your signature looks like and even if they did, its very easy to fake a signature. Any theft can practice for an hour or so and easily learn your signature.

What the OP is asking is a signed messages pretty much and if you know the public key of that particular individual you can verify if they actually said what they said. Its a smart way of verifying whether a particalaur person owns an BTC address without having to make them send a transaction.
2  Economy / Gambling discussion / Re: Your no KYC verifications should not only apply to online casinos on: December 04, 2025, 07:24:58 AM
Most people try and avoid KYC its not for to scam the government or anything but its for privacy reasons and to prevent identity theft. There are so many leaks these days that people are not comfortable giving their ID for every service that they use.

If you want a bank account you need to give the bank your ID, most people are fine with this because they trust the bank. Same with a large exchange like Kraken or Coinbase, they trust those companies. However we got so many medium type of casinos that werent out so long asking for KYC and there is little knowledge of where this KYC is actually kept, how can we trust that our identites will be protected? Most casinos would keep it safe but there is always a chance of a leak and the only way to protect against this is to do as less KYC as you can.
3  Economy / Gambling discussion / Re: Which one is responsible for gambling addiction: Livestreamers or Youtubers? on: December 03, 2025, 06:38:44 AM
If YouTube influencers can fake their videos and edit them just to show how lucky they are, livestreamers can also use sponsored accounts or virtual balances. Still, I think that whether they use real money or not, they share everything in real time, and they show that gambling is not easy and is actually risky. this presents a more realistic perspective of the industry compared to edited YouTube videos that discuss only positive experiences and big fortunes made. What do you think?

Is there a difference between the two, most livestreamers are on youtube and many times most youtubers go live. Sure you got twitch and tiktok however these platforms don't really make a difference. The issue that I found was that you got some influencer and you see him making $50K bets left and right, most of the time he wins.

Then next time he is betting or trading on another website and his bets are like $500 or $1000, it makes no sense and you can see how sketchy these people are. Why would you gamble $50K everytime on one platform but gamble 1/10 the size on another platform?

You can also just have 2 accounts, make a bet on one account and take the opposite on the other as a hedge, and in case you lose, you are not really losing anything except the spread.

I dont think the amount of years you are gambling have anything to do with how much risk you take. Like you said your friend which has gambled 5 years, supposedly he has lots of experience already but he still loses money, so obviously he doesnt manage risk correctly. Sure gambling is against you but most gamblers lose because they go on tilt and they don't control their emotions.

Many gamblers would be better off if they had a manager that would watch how they gamble and when they are starting to get emotional and go on tilt, they would be forced to quit playing and come back the next day. However this is why you have so many that gamble for decades and yet they still keep losing money.
5  Bitcoin / Bitcoin Discussion / Re: Will Satoshi move any Bitcoins in 2025? on: December 03, 2025, 06:29:42 AM
Honestly, sometimes I have this hunch about Satoshi losing his private keys because he under-estimate his project and thought the value of Bitcoin would not go as far as being worth over 100,000 dollars.

Anyways, if Satoshi managed to way for more than a decade and kept holding, why would he move his coins now when we started to enter a bear market.

I would only expect Satoshi to move his coins (assuming he still has access to it) if the value of Bitcoin reached half million of dollars per coin, some price which is very hard to ignore, even for the creator of the project itself.

I dont think it matters what the price is. He has so much coins, he could of cashed out all his coins when Bitcoin was $30 a coin and been set for life. Do you think he is holding on to $500,000 instead of $100,000, so he can have $500B instead of $100B, when you have that much money does it really matter.

Its not that the price isnt high enough for him to cash out, his goal wasnt to make money it was to fix the financial system. Hence why he disappeared and never sold any of his coins. This is why that prediction market is silly because even a 6% chance which is what it was when I made this thread, was already overpriced when we all know that he wont move his coins ever let alone till the end of the year.
6  Bitcoin / Bitcoin Discussion / Re: Bitcoin tx fee below 1 sat/vB on: December 03, 2025, 06:25:04 AM
Its has been 0.2 sat/vB for a while. I was sceptical to make any transaction lower than 1 sat but it actually worked. One thing to keep in mind is that many pools refuse to broadcast any transactions less than 1, so it might take a while for it to confirm but it will confirm. I think the lowest is something like 0.18 sat/vbtye and I just used 0.20 sat just to be sure it would work. I had RBF enabled so I figured might as well try it, took a few hours but it confirmed.

Etherum is similar. Remember how it cost $50 to send USDT back in 2017, well now you can do it for pennies. I think everybody has moved on to L2 or Solana and nobody uses Ethereum anymore. People got tired of being robbed paying those huge fees and moved on the Arbitrium or Solana.
7  Economy / Trading Discussion / Re: TRADING FROM 5 YEARS STILL IN 30k LOSS on: December 02, 2025, 07:18:03 AM
99% of all active traders are like him, go to Wallstreetbets or any other trading forum or website. Doesn't even need to be crypto or stocks, its the same for forex, options, commodoties and everything. Most traders lose money long term. Many in crypto made it because crypto went up very fast, especially alts and if you got in at the right time and got out you could of made lots of money.

Tradings stocks is much harder than crypto. Crypto is more transparent and should be easier however you are still against whales and people who have more money and knowledge than you. So you need to realise that doing this long term, especially for income to pay the bills is not feasible. Sure there are most that do make it, but most just end up losing their money and they give up.
8  Bitcoin / Bitcoin Discussion / Re: what if the block reward goes to 0, the tx fee cannot support such high hashrate on: December 02, 2025, 06:39:11 AM
There is a serious bitcoin security problem one the road.

What if the block reward shrink to low after ten years, but transaction fee is still as low as now?

Miners cannot keep such high hashrate because of low total reward. But the AI calculating power is growing fast.

IF bitcoin network difficulty collapse, it would be very easy to do 51% attack by.

Therefore, something must be done...

It will take much longer than 10 years for the block reward to reach 0 or close to 0.

In that time bitcoin will be more known and there will much transactions all the time. Even if the transactions are low like they are today, the difficulty which controls the speed of the blocks found, will just adjust down, so when many miners stop mining because its unprofitable, the difficulty will go down and it will become profitable again.

Obviously if block reward is almost 0 and there is almost 0 transactions then yes perhaps its a problem, but if bitcoin doesnt have any transactions in 10 years then we got bigger problems to worry about.
9  Economy / Economics / Re: bitcoin vs oil on: December 02, 2025, 06:35:55 AM
Oil and Bitcoin do have some similarities and differences. We all know that oil is not unlimited unlike fiat its capped like Bitcoin because there is only a certain amount of oil left in the world, now that is a huge number but its not unlimited, both have capped max supplies. Both also can be used as hedges during certain times, like if there is a brink of war, then obviously many will hedge their stock portfolio with oil because stocks go down and oil will go up, its similar with bitcoin.

The biggest difference between the two is that oil is very difficult to store. You cant keep it on your wallet, its huge, its needs proper storage, its also very heavy, much heavy than gold when it comes to a fix value. This is were bitcoin comes out ahead, you can pretty much just memorize your seed words and thats all you need to hold your crypto. Oil has its own ETFs, called the USO, but its most commonly traded on the futures. Bitcoin has its crypto exchanges, bitcoin futures, bitcoin etfs, etc. So bitcoin seems to have more accessibility if you want to trade it compared to oil.
10  Bitcoin / Bitcoin Discussion / Re: China warns of rising crypto risks, calls for tighter crackdown on: December 01, 2025, 06:24:01 AM
I remember back in 2013-2015, China banned and unbanned bitcoin so many times that I couldn't count. There was a meme with an animation about Bitcoins price being too high and China saying "hello Internet, we ban bitcoin" and the price went down.

I think the last huge impact that China crackdown on Bitcoin was when they targetted miners and there was a massive hashrate decrease, the largest decrease I think ever and after that China really wasn't that effective on moving the markets, right now its mostly the United States and Donald Trump.

Its funny because I think I read an article a few days back where China might "go easy" on bitcoin and now I read this article which is the complete opposite.
11  Economy / Economics / Re: Silver as an asset for investment diversification on: November 30, 2025, 07:43:43 AM
I got burned investing in silver back in 2011 or so, there was news such as "China buying Silver in unlimited quantities" and price kept rallying and rallying people were calling for $100 for silver. Then it peaked and it fell hard, I think it bottomed at $10 or close to it.

Gold on the other hand peaked at $2000 and bottomed around $1000 a few years later. You would of lost close to 75% if you invested in Silver and only 40% if you invested in Gold. Then from the lows of like $12 to $56 current price you got a yield of 366% while Gold which bottomed around $1000 and peaked at $4200, yielded 420%. So as you can see Gold is the smarter choice.

Silver can be mined easier and there is more of it, so price is more volatile, its not as scarse as Bitcoin or Gold.
12  Economy / Gambling discussion / Re: Which is more disastrous? Winning/Losing Streak. on: November 30, 2025, 06:03:39 AM
What is more dangerous for a new gambler especially someone younger is having a winning streak. Because a new young gambler like that doesn’t understand it was just beginners luck, they will think they have some skill and decide to make a career out of gambling.

Then they will start to lose and they will fail to give up. When they run out of money they will need to borrow money and they will also lose that.

If they started losing at the beginning they would have just given up at the beginning and never would have got addicted compared to the other player.
13  Bitcoin / Bitcoin Discussion / Re: Will Satoshi move any Bitcoins in 2025? on: November 30, 2025, 05:58:20 AM
Yeah there is less than a 1% chance right now that Satoshi will move his coins, when I made this thread it was something like 6% and a week or two prior it was 13% or so.

Back then it would have been worth entering, now not so much for such little gain but it’s still better than any return you get from a savings account I guess.

Next year this bet will probably return and it will start around 5% I’m assuming because it’s the current yield rate for lending stablecoins which are close to what the US bonds are paying.
14  Economy / Gambling discussion / Re: Why we don't want KYC on casinos but happy to comply with banks? on: November 29, 2025, 10:57:44 PM
Well most people don’t have an issue with KYC with banks or the government or even the police and one reason for that is trust.

Banks generally are very secure and you never heard of a bank having some leak where lots of peoples identities are stolen. But with crypto it’s very different. You need to trust that the exchange or casino has good employees and won’t leak your info.

The more times you KYC the more chances you have for identity theft and many refuse to do so. But casinos and exchanges don’t have a choice, they are just protecting their butts in case the regulators come after them.
15  Economy / Speculation / Re: What can you do aside from sitting and waiting on: November 29, 2025, 10:54:26 PM
When the market is down, what should we do? Should we just wait and watch the market’s every little move? No. What else can we do to earn money? That is what we should be asking.

First, don’t forget that DCAing is a notable strategy. Instead of just waiting, this can be done to maximize the time where bitcoin is declining. Second, find side hustles that pay in bitcoin. There’s a lot of works in the virtual world where they pay in bitcoins. Third, learn more. Learn new skills if needed. But just try to learn more about bitcoin. I know I am already familiar with bitcoin, but there’s too many things I have not encountered yet and I believe I can be of better part of the society if I did understand that experience.

Yes you basically buy it and just don’t check the price anymore. Most investors which are profitable are those who just buy it and forget about it for a few years and sell it then. These are generally retirement accounts where people buy and hold for 25 years and then retire.

Active traders who keep checking the price everyday and trading usually don’t make any money long term. It has been proven many times that buy and hold is the best strategy and to avoid overtrading.
16  Economy / Speculation / Re: Weakening of thinking when the market changes suddenly. on: November 29, 2025, 04:52:45 PM
Looking at the Bitcoin market, the price can rise sharply and fall rapidly. But why should we panic? Isn't Hold good solution? Why sell?

I've thought about this several times. Many people sell Bitcoin when the price drops. Is it because their thinking is weakening?

Many people sell all their investment when price drops, its not only bitcoin. Most people buy assets when the price is rising and sell assets when the price is falling, basically the opposite of what they should be doing.

Its the same with stocks. Why do you think the stock market always goes down faster than it goes up? It always goes up slowly like taking the stairs but when it falls, it falls fast and its mostly due to fear. People panic and they dump their investments at once and it causes price to tank. Its the brave that are there buying when everybody else is selling and the brave who are selling when everybody is buying. But this mentality is difficult to master especially when you are dealing with money.
17  Economy / Speculation / Re: Is it the fear of big crash that has stopped Satoshi from selling his bitcoins ? on: November 29, 2025, 04:49:47 PM
Unless he decided to mine with a different computer, its most likely he never sold any of those coins. Years after his disappearance people have observed how the early blocks were mined and they found a pattern and this pattern stopped when bitcoin gained popularity and was taken over by other miners.

I don't necessarily think that he mined in late 2010 with the other miners because if he did, most likely he would of used his original setup which we would have detected if one of those coinbase blocks was moved or sold. He most likely didn't think his mining lead to any pattern to identify him, which leads me to believe he just didn't sell any of it.

Who knows his financial situation, he might of been old and well off and already had a big retirement fund, why risk exposing yourself, and what would you need to spend a few billions on anyways?
18  Economy / Speculation / Re: Why Is Bitcoin Down? Blame Trump, Says Economist Paul Krugman on: November 29, 2025, 08:53:38 AM
Well there were two reasons for that crash on Oct 10.

The first one was the Trump tariffs that he threatened it shook the markets and crypto and stocks took a huge dive. Crypto was worse, especially alts because of bad liquidity in exchanges and there were a few coins which went -99% pretty much. Many people were liquidated.

Another was the MSCI move against MSTR. There is a chance that MsTR might be removed from many indices and as a result it led to people dumping the stock. If the decision in January is that they are allowed to operate as a fund then it’s good for crypto but if it’s the latter it’s bad.
19  Economy / Speculation / Re: Take your decision if bear or bull now. on: November 28, 2025, 07:10:37 PM
In my opinion, I think we are short term bullish, medium term bearish and long term bullish. Pull up a chart for the weekly for BTC and its clearly explained.

We bottomed at around $81K or so, lots of liquidation and now we are bouncing, so we might rally until $98-$100K area, however that area has tons of resistance, most likely it wont hold and we will reject it and then break $81K and then head down to the major support area of $74K.

This area is significant because it provided good support on April 2025 and it was strong resistance on March 2024. Most likely we will revisit this area and this is when the bull will return and we might head to a new ATH.
20  Economy / Speculation / Re: Can Bitcoin bounce back to 100k on: November 28, 2025, 07:07:48 PM
If you pull up the daily chart for Bitcoin on Coinbase you will see that bitcoin had decent support at $98500. This area held in the Summer and held in November before it broke. Traders are going to be eyeing that area. Most likely there is going to be massive resistance at the $98500-$100000 area.

Those people who got overleveraged and they are still not liquidated will most likely want to get out at $100,000 or right before it. So I think whether we will see a new ATH in the next few months depends alot on this area.

If we are in a true bear market then Bitcoin will not cross and stay above $100K, if it goes then it turns bullish again. December is going to be choppy due to the holidays.
