If you see comments here about investing or brokers, they are scams. Videos about cryptocurrencies, evidently including ones that are just about the underlying technology/math, are hotbeds for attracting nefarious actors preying on the impressionable. Also, hi! If you’re new to this channel, most of it is about visualizing math. I get it, you probably landed here searching for how BTC works, not to spend your afternoon getting pulled into learning about, say, prime numbers or problem-solving, but if you have a moment take a look at the rest of the channel, you may enjoy what you find.

It started as a joke/proof of concept, got some traction inbetween and now the market is flooded with so many crypto-currencies, it's a joke again - especially after Elon Musk on SNL. Plus the examples showed not only how it's not able to work with modern transaction numbers (visa example) and because the blockchain is forever growing, so will the computational power needed to create new blocks. And so will the computer-memory needed to save the blocks. Whereas banks can delete transaction histories from 40 years ago or dead people, blockchains will contain these forever.

Marc Ricci

@Theo Pantamis Thank you.
Theo Pantamis
Theo Pantamis 2 gün önce
The difficulty of mining is adjusted so that it is always possible for at least one guy to mine. Now if more than half of mining is maliciously cooperating to act as central authority then there is nothing users can do :/. The assumption in Bitcoin is that this is not the case. The best they can do is planning a massive change in the hash function used in mining for another one so that the miners have to throw all the mining equipment for new ones. Also, if the value of the coins decrease, the malicious miners are losing lot of money to mine without having enough to pay the electricity bill.

There is no money - bitcoin is a purely digital currency, meaning it's value is completly detached from any real world object. Whereas national currencies like the dollar are not backed up by items, it's value is determined by the trust into the entire economy using the dollar. As long as I can trust that my dollar could by me a bread at a US store, I can comfortably get some dollar even while sitting in Simbabwe. Sure I won't go to the US store, but there are people going there and they might happen to have Simbabwe money they wanna exchange at some point (obviously the biggest actors are banks and funds and governments, not folks sitting in fron of stores). So technically, real world currencies also rely on trust. If I loose the trust into someone using the dollar, I'm not getting any myself. But given the economy based on the currency, it's unlikely to significantly fluctuate in value. Ofcourse without any economy building a backbone for bitcoin, it's value is ONLY the trust and nothing else. And the real economy not only offer a security for a "lowest" value, but also an upper one. The value cannot explode as this would destroy the economy and thus reduce the value again - offering some stability further enforced by national/central banks who actually control the flow of money to some degree. Without any of these binding principles, the value of bitcoin, meaning the real money people are willing to "entrust" into bitcoin, can jump anywhere from zero to infinity. Something commonly known as "bubbles" in investment. Meaning people use real-world money to buy Bitcoin because they trust that someone in the future will want Bitcoin so much, s/he will pay them more money back (or offer goods/services of higher value). That's where the money-value of Bitcoin comes from and given the recent crypto-currency-crash thanks to Elon Musk, it shows how easy this trust can be undermined. The same is not true for the dollar, because even if some tech-guy makes fun about that, there is a gigantic industry which solely relies on the dollar and thus, will not bother with whatever he might say.

And why anyone whant to have usless thing like this....(confuse skreeech)

Early on, it was a joke currency. Nowadays it's an investment - people "want" Bitcoin in hopes it will become more valuable over time and they can sell it for more. Until Musk makes a joke at SNL and the suddenly nobody wants it anymore and the value drops.

Question about mining. If the reward is given to whoever guessed the result first, is it possible that you can mine forever never earn anything?
Romain Roche

Absolutely. Especially if you have a small mining rig. That's why people their mining power in pool, so that when the pool mine a block, the reward is split between the miners.

Im not smart but how does creating rewards out of thin air work? A value of a thing is detirmend by the demand. So the world just has to dissagree on the value of the currency you just created and added to the economy and its worth nothing. crypto sucks ass because there arent any real life assets that can represent it like USD for example. Dont get me wrong the idea is there like stable coin etc. But this doesnt mean that stable coin creator actually has those amounts of dollars stuck in a bank somewhere. it doesnt make sense and I will never trust it.
Romain Roche
Romain Roche 5 gün önce
@SprinkledCroisant about who decide how much coin you get, the reward per block was decided in advance when the protocol was invented. If someone tried to increase their reward, the block they just mined will be ignored by other people. So there will be only 21 million btc in circulatiom. For this to change, you would the majority of the network to agree, and it's not in their interest. About the dollars, a lot of dollars are created to be injected in the economy, there is not maximum amount of dollar in the economy.
SprinkledCroisant

@Romain Roche How is dollar worse? also sure miners are rewarded for the work. But my company doesnt make dollars to reward me for my effort? money gets circulated in many forms. Then again the same can be said for circulation of bitcoin. Only the way the video explains it is that the creation of these new coins has no logical origin and is not regulated who decides how much coins that person will get? The USD gets added currency when the economy grows and many other reasons. This adding is regulated by banks and the goverment. If anything mining is and sounds highly sketchy.
Romain Roche
Romain Roche 5 gün önce
In a way, it's not absolutely out of thin air. Energy is used to secure the network, and miners are rewarded for that. Also if your concerned about new currency being injected in the market, dollar is definitely worse than bitcoin.

I know it's quite an old video but I have one question. If you make a transaction to a certain message with your signature, what stops you from finding out someone's secret key. I mean you said that in the verify function you give your signature, pk and the message so what stops them from using the verify function to find out your SK and using it to forge your signature on future transactions? Thanks for anyone that manages to make it clear. And yes that's just for the purpose of knowledge 😅

@Michał Staszewski "what stops them from using the verify function to find out your SK and using it to forge your signature on future transactions?" nothing, they can try all possibilities if they want. The problem is that .. they are many of them, so much that trying all of them would take you too much times the lifespan of the universe to find them and without quantum computer there is no way to only try a clever subset

So, if it gets harder and harder to "mine" or be a block creator , and the currency has a limit by reducing the LD you get or increasing the time it takes to process. What happens when it bottlenecks to the point that its not feasible to be a block creator? And no one is doing it anymore. Wouldnt the ledger just stop and shut down overnight making the currency useless if no one can use the ledger?
Theo Pantamis
Theo Pantamis 2 gün önce
@shu There is no "cost of mining" from the protocol point of view. If for whatever reason, it is globally twice harder to mine suddenly, after 2016 blocks the protocol will divide mining difficulty by two so that blocks are still produced every ten minutes as usual. There is no high energy requirement needed in the protocol to work (but if you as individual you want to mine then yes you have to have enough energy available compared to other miners)

see cryptocurrency winning every fight. The future for it is big with the dominating assets gaining value in the coming years. To many, knowing when to buy and dump these assets looks like some sort of superpower. They can't help but follow speculations or eventually, emotions. The thing is, there are too many techniques out there and it gets confusing know what works. With my years of TA experience My recommended entries on bitcoin based on my TA has been getting with amazing return in P/L. Days ago, I gave a BUY when price broke it's resistance of 46080 with a TP(takeprofit) on bullish at 48000USD which saw +200% gains on a 1 ratio 50 leverage, just on a single trade

20:16 the example is not quite correct. The "Alice pays Bob 100 LD" message is signed by Alice and given to Bob. Bob will send the message to many nodes and many miners could include the message in their blocks. At some point a miner will create a block with the transaction received by Bob and at this point Alice should create an alternative block without such a transaction and compete with the other miner.

How do you cancel a transaction in the block chain? Let's say I order a pizza and write into the block chain "I pay Antonio's House of Pizza $18", and then Antonio runs away and never gives me the pizza. How do I revert the transaction to get my money back? In traditional money I can call my bank and say "hey yeah he screwed me over" and they'll restore the money to my account. But how can I do that when it's distributed? Who is there to call?

You can't, but that's the entire point. It doesn't allow for mistakes to be made on it, which is what makes it "Trustless". This might feel counter-intuitive, but this is a long-term good thing. What if all of global finance was forced to conduct ALL transactions on a Blockchain? They would never be able to cook the books or fudge the numbers ever again. All transactions would be permanent record, and impossible to reverse. Which, is kind of the endgame. IMO.

As soon as the transaction is in a deep enough block (two are generally sufficient) it cannot be cancelled. That's why Bitcoin is also called "electronic cash": once you paid in cash, there is no way to revert the transaction. Reverting is always up to your bank, they can refuse to restore your money. What it shows is that cancelling a transaction requires a third party or escrow that may not let the pizza seller leaves with your money if you didn't confirm you got the pizza. It is also possible to do that in Bitcoin by requiring several signatures to spend the coins (you can send your money in a kind of common account between you, the seller and the escrow before receiving the pizza). However, you reintroduce trust in the mix toward the escrow.

👆👆I have not imagine how my life would have been if not for cryptocurrency and investing. So many people are turning Millionaires everyday with the help of cryptocurrency but the problem is how to get a trustworthy broker and trade manager to guide you and help you invest. If you have not contact this guy them you are really missing out never thought I would be millionaires this 2021 after I lost the job to the covid19 last year. All I can say is thank you so much
