That one guy on Youtube said that Salano was gonna be big, guess he was right
Proof Of Space & Time – Chia
Do they have to be? No, check out nano.
It's a stupid human self-made problem basically… it is totally made up and unnecessary
This is literally why I never really started using Bitcoin. It’s so wasteful. Peer Coin solves that problem correctly even back in the day, if I remember correctly.
Tell me you don’t understand Bitcoin without saying you don’t understand Bitcoin…
In the past when someone wanted the best performance for their games they would often sell their GPU after one or two years in order to upgrade. These GPUs were of course used a lot, but unlike crypto mining GPUs they weren't running on maximum power 24/7 for two years straight.
The GPUs used for crypto mining have already gone through most of their life when they're done. So people are now less likely to buy used GPUs. Especially the flagship models..
I think Etherium should send out a notification to all miners that they will switch in, let's say, 1.5 years. Then the recent investments won't go to waste, and the miners can invest in systems that will benefit the new system instead. This way the miners don't have a valid reason to complain and the system can be changed. If they've already done this about a year ago then I hope they go along with their current plans 😀
Wouldn't this slow down the transaction speed significantly?
I wonder how many NFTs were sold with content about Earth Day 🤔
I think with proof of steak, you should also be able to use other currencies, like a percentage of the Bitcoin or maybe even a buy-in for the Bitcoin, that way it is at least not locked off to two people that have already gone into Bitcoin. Otherwise I think it's a good alternative
Someone else was talking about foldcoin and that is something I hadn't heard of before But it sounds like a good idea. Proof of Work that does something more than just be hard to do.
I think BitCoin will have to change to Proof of stake and/or useful work at some point. Too many people are starting to think about the environment and how they can make better choices.
I expect it will be a few years before we see anything big happening but I believe it will happen. BitCoin will change or it will be abandoned in favor of other cryptos that are better for the environment.
Ethereum is delaying POS every time they get close enough to it, and are now expected to transition only by 2023. Bitcoin users on the other hand are proud that they aren't transitioning to POS.
Because the environment be damned if it means you can make more money.
Crypto and NFTs are the biggest scams in human history, but sadly, as long as there are people believing in them, they're here to stay. We can only hope to get their environmental impact minimized.
Hi Hank,
I was a bit disappointed that you only mention the mainstream narrative, without mentioning the lightning network or the fact that Bitcoin can help handle the change in loads to the electricity network.
the vast majority of bitcoin miners are already incentivized to use renewable energy because it’s free. i don’t understand why this is such a hard concept for people to wrap their head around.
look up what a governance attack is. every proof of stake coin is vulnerable to this. it’s a terrible idea to let the richest person make all the rules on the network. would be like letting elon musk run the us federal reserve
wow this is the first time any explanation of crypto made any sense to me…great job!
Nope. Your daily streaming habits, and high mobile networks ate hundreds of times more detrimental in a single country than all of crypto combined.
The central banks are just pissed because they can't control us anymore, and you're buying their propaganda.
Crypto energy usage would be irrelevant if people would stop being anti science morons and fully embrace nuclear power. Stop fear mongering something you don’t understand and allow society to finally progress.
Shish… You don't solve a super complex math problem – you just brute force generate hashes from data (with incrementing counter and timestamp) until one matches currently defined rules (meaning at lest how many zeroes the hash has at the beginning…). Calling that a math problem is just camouflaging the stupidity.
Why is that so hard to say something like this for all the explainers?
And yes, I programmed both for banks and bitcoin nodes so I'm quite confident in saying that this mess is a solution in search of a problem (that's the reason why after 13+ years everyone is desperately still trying to figure out where this garbage would really be useful).
Thank you! Love this vlog channel!
Okay, so everyone who has made a transaction in the blockchain has a copy of the blockchain? Does that mean that they have a 400 gigabyte file in their computer that they can't delete? What if they aren't connected to the internet when a transaction happens, do they then have an incomplete ledger? There are so many ways for the blockchain to fail, not to mention all the fraud and theft.
How much energy does YouTube use? About 600 TWH per year or roughly six times that of Bitcoin. Video gameplay consumes about 105 TWH per year or about the same as Bitcoin.
How much energy does the current banking system use? About twice that of Bitcoin and likely doesn't include all those employees driving to and from work. And much of the world is still unbanked. Bitcoin fixes this.
The value is in the Bitcoin settlement network:
Nasdaq Nov 30, 2021: 'Bitcoin Is The World's Most Efficient Value Settlement Network ~ settling more than $60 trillion in transfer volume to date.'
The Dailyhodl Nov 30, 2021: 'The Bitcoin network processed an estimated average of $489 billion per quarter in 2021. PayPal processed an average of $302 billion per quarter in 2021.'
Capitalism is a virus on Earth!
Misinformation. Look online at the 05/02/2022 Bitcoin Mining Council's response titled, Bitcoin Letter to the Environmental Protection Agency. Clarifications are there.
We’ve neglected all major environmental problems with 26 failed cops….this is a drop in the ocean
I love that Apple products are the metric for electronic waste.
doesn't that just make crypto into stocks?
I have solar power on my house, and the feed in tariff I get paid by the power company is lower than what I earn mining bitcoin on my RTX 3070. So, my RTX 3070 uses some of my excess solar to make a bigger return. I earn more from mining with my excess power than I do from the grid.
Proof of Work is the only way to create an uncensorable decentralized money. sorry ecogeek.
positive feedback from ☝️ I received 2BTC in my blockchain wallet I really appreciate your effort..
This is a rare bad video by scishow. You are helping legitimize ponzi schemes and destroy the environment. Very disappointing
I'm not going to watch this because there are already alternatives to wasteful proof of work strategies like Bitcoin. It's Proof of Stake. Ethereum 2.0 is going to be proof of stake.
Thanks for this, definitely moving away from Bitcoin and will be investing in some of the others
The one thing you got horribly wrong is this final statement “ Bitcoin will use up a lot of energy every time someone make a transaction”. It is so wrong it is not even funny. Please dig a little deeper on this. Bitcoin transactions have marginal additional cost. There are blocks with 0 transaction (excluding coinbase) that use the same amount of electricity. You can add 3000 transactions to that block and would take the same amount of electricity. Electricity used up is for miner rewards, not transaction.
And all that effort and energy so people can speculate on virtual currency. Its like 1 step forward 2 steps back scenario.
This is an over-simplified and half-baked assessment of bitcoin's power use, power sources, and environmental impact. Did you bother to consider how much power is consumed and waste generated by our current financial system? E.g., how much energy is consumed just operating ATM machines around the world? What about the cost to build, maintain, and heat/cool the world financial system's collective office space?
Bitcoin solves many of the worst environmental and social maladies caused by our current financial system (and that means 99% of our problems). The current system is designed to profit the greediest and most corrupt people in the world who, in turn, use their wealth (proof of stake) to further corrupt and manipulate the system to their benefit, regardless of detriment to others or the ecosystem.
The proof work algorithm employed by bitcoin makes it incorruptible and cannot be manipulated by political interests or other organizations trying to gain advantage over others. This is in contrast to proof of stake mechanisms where those with more tokens (stake) are allowed to validate a larger percentage of the transactions and earn more. Proof of stake also gives those with the most currency more influence over future changes to validation rules, thus it can be manipulated further.
The current failing financial system, based on fiat currency, runs on both proof of stake (the more money you have, the larger your stake and influence/reward – e.g., who gets bailed out during financial collapses, and who doesn't?) and proof of work (the US dollar is ultimately secured and backed by the US military).
it's worth mentioning the bitcoin network uses more renewable energy, specially solar, than any other sector of the world economy
Pure Propaganda Down Vote Who paid you for this piece of propaganda??
