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.
I'd recommend not just reporting, but also replying to them, explaining to any potential readers how their advertisement is a scam. Commenting is quick, and could save somebody hundreds of dollars! :)
Thank you so much Lisa

You have no idea how much I've tried to find an article or video actually explaining how cryptocurrencies work. Everyone else just goes around with analogies. They probably don't understand fully themselves. Thanks man.
Something that should be obvious to any computer scientist: This is terrible in practice. It wastes the same amount of energy every 10 minutes regardless of how many transactions are there. This amount of energy is only decided by how much energy miners want to waste: the answer is as much as possible, while still having a profit. So every 10 minutes miners can spend 6 bitcoins worth of electricity and still have profit (0.25 btc). The more expensive crypto gets, the more energy it will waste.
@Alberto T. Yeah, it's not scalable. Note that proof of work is one solution to the problem; there are many other ways of doing it. (Ex/ proof of time, proof of stake, proof of burn, etc...). Also, if the amount of time was reduced to say 0.01 seconds instead of 10 minutes to make it more practical, there will be too many forks & network spam. The blockchain itself also has poor scalability, though, considering that transactions from a single individual are spread out and all stored separately. It is a neat idea. There are just too many downsides.
@Tobi I'd probably go with centralized and regulated currencies because they seem way less volatile, reliable and secure. And if cryptocoins ever become the go to currency, central authorities and the wealthy will centralize their hold on it, so I don't see how that's ever going to become a better alternative. Maybe the players and the chips would be different but the game would be the same.
@Tobi Inflation is good when regulated. Without gentle inflation, economy and money flow stagnates. Wealth hording isn't good for you. There's a reason gold standards had to go away. Maybe look into the topic.
So true!
This is the clearest video I’ve ever seen, and I still don’t get it.
Exactly.
I think the first thing to get down is the notion of decentralized ledgers. An understanding of where the actual bitcoins are in the whole process is vital to understanding what is going on. Everything else is just applying cryptography to deal with the various security problems that these decentralized ledgers would otherwise have.
Acctually tho wtf

Most explanations I’ve heard are the same regurgitation of simple analogies with a twist of their own life story but what I want to know is the nuts and bolts of the whole operation. That’s what has been annoying

It's an extremely information dense lecture. You have to watch portions of it again and again to grasp the underlying concepts. But once you've finished it, you feel so damn confident.
Yet this 26min video only scratches the surface. To actually understand the data structure of a transaction, and a block, to understand the stack based scripting language of Bitcoin, and so on, goes way beyond this video.

I have watched many, MANY, different videos on "what is Bitcoin." This video has been BY FAR the most helpful video. I tip my hat to you my friend, and a job well done.
Sorry to hijack this comment to ask my question, but I'm still kind of confused. Who's giving out the public and private keys? And how does a miner join the network? Like if I wanted to start mining do I need a friend in the network who can connect me? Or is there some bitcoin authority giving out keys and adding them to the network, so they know who to ping if they win the lottery, and so others know the ping them if they've won?

The worst bit is how most are too lazy to set the bots up so they change their profile pictures, so you have a bunch of default picture KZhead users talking to each other. I think even worst than that, is that they DO change the profile pictures of the bots, but they are all really high quality portraits of middle class business people smiling. I've once come across a comment chain that had two bots with the same profile picture of the same man, but under different names.
In 2019, people have realized there isn't going to be one crypto to rule them all. You're seeing vertical solutions where XRP is focused on payment problems, Ethereum is focused on smart contracts, and increasingly, bitcoin is a store of value. Those aren't competitive. In fact, I want bitcoin and Ethereum to be successful.
Another thing- people began to realise that bitcoin wasn't rising in relationship with the US Dollar; in fact USD is CASCADING downwards with respect to cryptocurrency!
this was awesome! I was having trouble on understanding the nodes vs. miners as well as the random number / difficulty adjustment but this totally cleared it up!

You can verify the transaction with a RPi, mining is only needed if you want to create blocks, anyone can check if his transaction is in a block or not.
@@theopantamis9184 i know, right? even with incredibly helpful explanations like this video, many people won't move past memes and gut feelings into a deeper understanding.
@@theopantamis9184 I haven't yet understood the video fully so this might be a dumb question: If there are multiple miners trying to put together a block and only one guy is successful in making one (by reaching the right amount of zeros in the hash), doesn't the work performed by all other miners go to waste?
@@vishank7 All of the work is "wasted" in the sense that it doesn't actually do anything useful. Its only purpose is to make it cost time and money to make a new block. As more people start mining, each block requires more effort to mine and gives less reward. It is a lot like gold mining in that way. If you are mining gold, all the digging you do that doesn't lead to finding any new gold is wasted. But usually there is no way to find gold without wasting a lot of time on misses. The more people mine, the deeper you have to go to find new gold, and the less you usually find. The difference between bitcoin mining and gold mining is that gold has some real utility outside of its value as currency, while bitcoins have no other utility. However, most gold ends up locked away in vaults anyway, so I think it's a reasonably good analogy.
To verify requires almost no work, that is to read the block chain to find the transaction. Work is required to validate the transaction, that is to write it to the blockchain. A transaction will typically be written to the blockchain with thousands of others.

Bitcoin is the future of crypto and questions traders ask themselves now is if this is the right time to invest? Before jumping to a conclusion I think you should take a look at things first. For the past few days, the price of BTC has been fluctuating which means the market is currently unstable and you can't tell if it is going bearish or bullish. While others still continue to trade without fear of making a loss, Others are being patient. It all depends on the pattern with which you trade and also the source of your signals.

10:00 "The history of transactions is the currency" interesting Edit: 17:30 I love how I now know what a block chain is, and it wasn't as mind blowing as people on the internet made it seem. And I'm pretty sure blockchains are done in introductory coding courses. (Though not as complex). Edit 2: 18:25 so THAT'S why mining is profitable. I get it now. That circles back to the claim made ~10 mins in. Edit 3: 21:15 So, bitcoin 'authority', in essence, is computing power, and bitcoin 'identity' is the a blockchain made by the original owner? Great video. As you can see I am still shaky on complete understanding, BUT this was the only useful explaination of Bitcoin and crypto I've seen so far (for me). So I am greatful. and maybe this will lead me to understanding others.
Every new day, Bitcoin gains support and patronage of more and more politicians, billionaires, finance institutions and institutional investors. Could even surpass the 60k June 2022 forecast.
Very true. Just recently Fidelity said they have been accumulating bitcoin since 2014, then again, it was announced that the SEC will likely heed to calls for BTC approval come 2023. This shows that whales and smart funds are buying bitcoin quietly, but they won't let the public know. It's such a pity that people are worried about btc not reaching a particular price at a given period instead of securing their place in the future with btc.

Nice to have this explained so calm and clear. Thanks.
fascinating video as always, I rewatch this second time and still find it very useful to remind me again. did you use only the manim library to create all the animation
Nice video, but How do we get paid?
Through what kind of job?
Is it Online Investment?
@@murraydickson6336 Yes, online Investment
I get paid directly to my account
@@murraydickson6336 how please
This is the best explanation I have seen thus far. Am recommending this video to everyone who has asked me how it works.
Someone being clear, thank you.
You do understand that paper money has no intrinsic value exactely like bitcoins right? The only thing that makes paper money valuable is that people believe it has value. If people massively started agreeing that bitcoins have "the same value" as paper money, they EFFECTIVELY WOULD HAVE the same exact value. Are we there yet? Of course not. But that does not change the point.
Great explanation, thanks. Im sharing it to everyone right now.
so no1?
Chris Barnatt of Explaining Computers does a good layman filled explanation of blockchain which sneaks ahead of this video, as good as this video is, and I'm inclined to put his video first and this a close second as most gaps and question marks are covered with both videos.
This is the most educational video I’ve ever watched thank you so much for real🙏
one of the clearest explanation. Thank a lot bro!
You are a life changer. I am not exaggerating. Absolutely no one can explain complex seeming things simpler than you. You are doing a great service to humanity. Thank you
24hrs hack service on IG, they helped to save my life from debt. Thank you hacksolvent
Yes :D
Thank you so much for the seeds of knowledge you planted in my brain
This is the video that opened the world of crypto for me. Thanks for that!
There's a few questions that I have about how cryptocurrency works that are not addressed in this video, specifically, the costs of transactions and storage: 1.) How much storage space does a ledger take up? If everybody has to have a copy of it, won't it eventually become so big that average consumers won't have hard drives big enough to store it? If so, how would it still be reliable? 2.) How much energy does it cost to actually mine a coin, and how does that cost not offset the value of the mined coin?
@Digi both BTC and Monero also allow for storage and usage of the pruned chain, which is about three times smaller; the mechanism was described in the original whitepaper about BTC by S.N.
I am glad there are smarter people out there than me. If it was up to me, we'd all still be living in huts out in the jungles
😂😂
If it were up to me we'd be in tents in our bedrooms😂😂 like children
It's not about ppl being smarter than you. It's who can understand the slight of hand better than others. Remember, currency is about what really doesn't exist. It's just an iou, basically.
made my day btw: feeling the same
That would probably be better
I only understand the ledger part, the rest I need to figure out.
re-watch the video..it took me 3x to get beyond the ledger part with understanding...
Your not the only one who feels like this😭
I've watched many different videos on the subject and even did a course - but this is the best explanation by far.
Top-notch explanation, very clear, I shall send this out rather than explain myself in future. I wish I had your gift for teaching. Thank you for your channel.
This video is about to start getting a lot of views.
Bcoz of dogecoin?
Dogecoin commentary via a certain tech reviewer brought me here even though he is emphatically NOT a financial adviser 😂
@@ActiveDodger marquee??😂😂😂
@@ActiveDodger same lol, came after mkbhd video
Why
Very helpful and simple video, keep it up.
This is the absolute BEST explanation of BTC I've ever seen. Thank you!
Thanks for uploading this! IIf you have a crypto/blockchain series I'm definitely in as a viewer
DANG...this still went straight over my head.
i know what you mean! i wish i had a brain.....
funniest sh!t ever LMAO
View it again and again, you'll eventually get it.
Love the comment buddy..................started to go over mine 4+minutes in
Lol, Feel the same.
One of the best videos so far I have come across that explains the technicality. I just love it. Thank you for this wonderful video.
Sir you join a professional company join.
This is still very complex, but on simpler terms. Replaying and taking notes is the only way to understand such information.
Thank you very much. I have been wanting to understand blockchain for a really long time. Your KZhead video was really helpful and fun to watch. You are really good at explaining the complicated stuff in a lucid way. You've got yourself a new subscriber. 😁
a couple hours later, a desk full of notes and now an actual idea what is going on. Best vid ! thank you my guy !!!!!!!

Finally understand the principles. I've watched a number of videos and even read a book. I'm either a slow learner, this is a great video, or both!
Thank you for your comment on this video, we'll keep helping you make better trade as much as we can.
The best explanation of cryptocurrency I have seen yet, thanks!
