    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've seen a few crypto youtubers mention in their videos about scammer who might comment, or reply to one of your/my/our comments with a series of seemingly random numbers and symbols... and they (the youtubers) warn not to reply to them. Well, I did reply to a couple because they commented under the youtubers user name replying to a comment I made on their video, and I didn't know what it was. So I just replied "What is that about?" Am I in jeopardy because I replied to them? And if so, what do I do?

    what does it actually produce? nation states produce currencies to facilitate the exchange of goods and services. What does a bitcoin represent? On what is it founded? I believe it is all nonsense. A scam. It is all based on trust - faith - and when (yes, when) that vanishes the game goes bust and the suckers ask government to bail them out. I would suggest to anyone who is dabbling in crypto-whatevers to recover your money - yes, real money. I am going to pursue this inkling I have that these schemes are associated with libertarianism and irresponsible citizenry. Pay your taxes, participate in tangible economic practices and quit trying to scam other people into floating your boat.

    @Donal Dubh Greg Foss, a Canadian who traded bonds and credit for a few decades talks about how bitcoin is a very realistic hedge (wrote an in-depth paper about it) and he is actually more worried about canada's situation than the US's. He's done some really good talks, you can find them on youtube.

    @plasticman2011 'hedges to irresponsible money printing' - and you associate that with bitcoin? cryptocurrencies which do not have a passing relation to real value? The worth of the bitcoin is illusory and a glittering fantasy for people who hope to get wealthy by doing nothing. That's the real source of my concern - the bitcoin reality is all greed and sloth. You worry about central banks? Hold up - are you American? yeah, that might explain some of your doubts - you have a privately owned and managed Central bank - weirdest notion I could imagine. Canadians have a Bank of Canada part and parcel of the government and pretty efficiently run. While the U.S. was foundering in financial storms Canada was in smooth water. We didn't allow those dubious exchanges and suffered negligible harm. I say lastly that I am no expert by any means but I am old enough to smell something foul and bitcoins and the ilk are damnably close to pure rot.

    The more I learn about it, the less appealing it becomes. There does not seem to be any practical value to it other than simple protest against "the man". The computing power could be put to much more value adding use such as helping SETI or simulation of organic chemistry interactions for treatment of various genetic disorders, etc. There is nothing wrong with money or its principle as credit against good or service. The problem is in people, and that problem will be quickly imported to crypto currency. No discredit to the video, though, as it is excellent!

    To me bitcoin is just a waste of shitload of energy for unnecessary bruteforcing, which doesn't take place in any other banking system. I get the idea of decentralization and privacy (I mean, the privacy is yet quite an awkward argument, cause the private banking is private after all, nobody watches your accounts cause why... until you are a terrorist, but then yeah better let them watch you, you know what I mean). But still, bitcoin is so pathetic implementation of such system, that I wanna cry. Everyone clapping happily simply doesn't understand the basics of it. It's the Middle Ages of the cryptocurrency and that's it. 99% of computing power is wasted for no reason. Making banking by bruteforcing. 1000 IQ solution. Cheers

Even the banks are using blockchain technology and guess what. They don't bruteforce the shas. Interesting, huh? Also, my "password-protected rars" weren't meant to explain the bitcoin, they were meant to expose its absurdity. Cause that's more or less the thinking of the designer. It resolves the problem in the stupidest possible way.

    They can choose which transactions go in the ledger or not. But they can't create invalid transactions/blocks.

    Can it become a problem of size at some point if the chain becomes to long (e.g. sending it over the internet or storing it locally) or is it possible to just use the most recent N blocks? I'm not specifically interested in Bitcoins or crypto currencies, but I really love your videos, these are qualitatively the best visualizations of math I have ever seen! I would very much appreciate your reply.

    We need that some peer keep the whole ledger which increases in size indeed. But storage is not an issue, it is quite cheap so there will be enough peer. As an individual, you can only keep the recent blocks because you only need to the unspend transaction outputs but you still need to validate every transaction. The later you start running a node, the more transaction you have to validate before starting being a peer of the network.

    Bitcoin/Crypto is NOT a currency. Its a cryptographic commodity. Big error with the presentation to not explain that. If you alter a balance sheet at minimum that has to adhere to database definition ACID atomicity, consistency, isolation and durability properties. However a modern currency is O(1) to make changes to interlocked balance sheets. Blockchain in some degree of Big Oh n factorial. Eg: if i want to transfer currency, or issue currency that's 'work' that is not intrinsic to the fundamental algorithm of the currency. You're only maintaining a database with the OPTION of degrees of security which may/may not be centralized or computationally complex. Problem with bit-crypto's are they ARE centralized because you have to all agree on the rate of work to mine the block chain and the number of transactions to sign, and with which function SHA, PBKDF2, Argon2, BCryptSHA256 etc. Good luck if you've invested millions in dedicated mining hardware and a non-elected central body that administers the block chain branches, changes the hash or rate of growth for mining the block chain. Of course it worth pointing out from an energy efficiency point of view crypto currency is GAME OVER for the environment. Goodbye ice caps hello 4 degrees C global warming.

    When you start the Bitcoin software it will search for other peers and ask them to share the blockchain from genesis block to current one. First the block headers (you verify proof of work), then the transactions. Then you have to validate everything and create the set of unspend transactions outputs by winding the blocks. Then you are like any other peer. This phase is called IBD (Initial Block Download)

    The cryptocurrency has a fresh record high for in three years last month as people increased their bids in hopes of making huge gain from the rise but as we can see now the market is very unstable , the truth is that you can always make more profit from tradn rather than just hodlin and waiting for the price of BTC to skyrocket . Indeed its a tough decision for both old and newbies whose intensions are just to hodl and sell but rather the potentials of tradn Btc would allow you grow your Btc not minding the present price chart and also saving your ass from any future deep that may occur . I started tradn with Andrew Hansen. since late last year and till date have made over 14 Btc even with the ups and downs since the journey. With andrewcryptotrading help I no longer have to worry about the rise and dip of Bitcoin , you can easily get to andrewcrypto. on :Teleg: ram : @ andrewcryptotrading

    Most newbies fail simply because they don't understand how the market works in general, or in particular how the market relates to the stock or currency pair they entering. If a retail trades doesn't grasp what the market makers are doing and when they are doing it, the greatest strategy in the world will fall. For new traders the markets are like entering an F1 race before you've passed your drivers licence test. I am a beginner i never believed i made £9,000 in just 1 weeks from trading and with the market. An expert financial analyst and he made me learn to read and understand the language of price action. He guides me with the exact time frame to trade and now I just received my first withdrawals of £9k in my bank account today I'm very happy, my advice contact him on mail and thank me later. I guess this is a good way to show my heartfelt appreciation for literally breaking the chain of my financial debt when I needed it the most. 《 Fedrickj002@gmail.c om 》

    If there's a tie in computational complexity you wait until someone adds to one of the blocks, doesn't that mean large companies or groups with high computational ability can bully and control the miners?

    No, because the next block can come from a small miner or a large one. As long as one entity doesn't have 51% of the total mining power, it will work just fine.

    Bitcoin is defying all laws of nature and TA in this new era with many speculations and many predictions gone wrong, it's outrightly wrong to just sit back hodl and wait maybe incur some losses along the line, that's a wrong mindset for an investor because as an investor finding ways to always increase and stack up more coins thereby making prof!ts should be the way of life, even experienced traders are in a doubt to take long or short position. People who invested in Bitcoins at the beginning or even in 2013 or 2015, when Bitcoin was crashing, have now become millionaires. I have been more skillful than lucky. Thanks mainly to the good time, my initial investment was multiplied by 5 In two months. After getting in touch with Robert Wilson, an exp:ert in cryptography, who showed me how to use her program to make transactions and got 14 bitcoin in 2 moths with him. if you are looking for a way to increase your portfolio or investment.

I kept hearing about "running algorithms", but never what those algorithms actually where! Secondly, I kept having questions after each segment of the video, and magically, you kept answering them! Needless to say, it was a great video and super easy to understand with the visuals and your explanations! Thumbs up from me!
