How much energy does watching porn consume? Playing video games? Watching a movie? Browsing Facebook? Using a ski chair? Visiting an amusement park? Going in vacation? Cooking your favorite type of food? Making ice cream? Driving to your friends? Listening to music? Concerts? Having a party? Banking? Casinos? As a species we use energy to meet our goals. Those goals may be situated anywhere in our hierarchy of needs.…

The almighty dollar rights all wrongs. If I’m paying for it, what do you care? This is a slightly dressed up Tragedy in The Commons.

Yeah I don't really understand -- normally people buying things (energy) at a price the supplier is willing to sell is good. If energy is priced appropriately, this shouldn't be a problem.

Are people concerned with the negative externalities of energy usage? If so, it seems like the real issue is that all energy use is "bad", anything that causes people to severely increase their energy usage is especially bad, and bitcoin is one such thing.

But even though it's bitcoin in practice, the real issue seems like not being able to correctly price energy.

Ok, I have to admit that I am one of those people who knew about BTC very, very early but never bought any. Now, of course I should have mined at least 100 back in the days, but anyways. The reason I have never mined nor bought into it is that I still, to this day struggle to come up with a real reason to do so. Am I getting too old? Do I not see the "huge potential" what it may become? Don't I want to get freaking r…

You can send me money across the globe without a middleman or anyone being able to block that transfer. That's it. If you don't want that, you don't want that. Some of us do.

That’s ignoring the middlemen who run the mining network, who you pay for every transaction, and the middlemen on both ends who convert to and from the real current which you use to buy and sell the things you actually use.

Similarly, any government which wants to can block the network entirely or require everyone exchanging into real currency to avoid transactions involving people who’ve violated local laws. Since Bitcoin by design helpfully gives them a full list of your past activities anyone considering ignoring those demands has to consider the risk of consequences for their participation at any point in the future.

Hey there. I'm one of those people who read Schneier's Applied Cryptography in highschool in the 90s, and immediately recognized the groundbreaking potential of using asymmetric cryptography for currency. I work in information security, and have seen first hand how our existing financial infrastructure is held together with string and scotch tape. For 10 years or so, every time I heard about some big credit card thef…

I 100% believe that legacy finance is a massive hindrance to the sustainability of our species,

Could you please expand on that? Why?

Earlier quoted context omitted.

It's about $7 at the moment to be included in the next block. A new block is added approximately every 10 minutes. Since bitcoin does not guarantee finality some services require you to wait for a certain amount of extra blocks after yours to reduce the chance of a change reorginaztion happening that doesn't include your transaction. Bitcoin will not function as a currency due to it's high volatility. For a more usab…

The public does not have proof that USDT is collateralized with real life assets. I'm not sure about USDC.

The public know that USDT is not fully collateralised with real life assets. This has been publicly stated on Tether page as well. So can we please stop parroting this USDT bullshit, nobody cares how tether is backed and with all the alternatives to USDT there is no reason to use it but from a perspective of ease-of-use and wider offering of trading pairs. You have DAI, USDC, TUSD, BUSD.... You can check which one is audited (USDC and TUSD) and will credit you fully if you need so. You can also work directly with USD at various reputable crypto exchanges (eg Bitstamp, Coinbase, Kraken).

This tether FUD always resurfaces as price goes up as people are butthurt that they did not buy the last dip. No worries, history will repeat itself. This year we'll see BTC hit 100k+ and end the massive bull run in 250k teritory by 2022. After that we'll see everybody dumping their cash in BTC and the bubble will burst on the wings of massive FUD & regulatory bullshit. Bitcoin willl drop to ~20k and cycle will repeat.

For those that weren't watching, this repeats itself every ~3 years for past 10 years. Keep watching the news... USDT stories will become more regular, next will be China bans, Russia bans... then we'll continue with EU regulation push, US regulation push, new tax laws....

The only smart thing you can do is start investing a small amount every week and forgetting about it. Cancel two lattes (or lottery cards, donuts) per week and buy BTC and ETH instead. Imagine starting doing this in 2016, when ETH was launched. You bought ETH for 1 USD. Today it's hitting ~1700 USD. You would retire easily.

Too bad you're so hard at work telling the world that crypto is a scam.

So, what about refunds when corporations rip us off?

And what about losing 100% of my funds when my key is lost or stolen? All keys are lost/stolen - it doesn't take a rocket degree to have observed that from human behavior.

Who enforces splitting of equity when some rich dick beats his wife into submission? The courts don't control any bitcoin keys.

The problems of bitcoin are proportionately larger than then problems with fiat. The only people saying otherwise are those that are profiting from the opposite perspective.

If we are not a bitcoin miner, then how will we get the funds to begin with? Right now I can trade fiat for it, but in the future my children would not be able to trade fiat for it (assuming it's as good as you say it is). So, they will become indentured servants to the bitcoin miners.

> I simply can't answer what BTCs and other crypto coins are actually good for.

Everybody here is missing out why Bitcoin was made in the first place: the 2008 crash.

The benefits of a globally liquid asset (not USD) will only be appreciated if you're living from a country that has a weak Central Bank.

- Nigerians use it to import goods from China. This guy can't source USD to purchase imports for his mobile phone business, so he uses BTC [0]

- Venezuela remote workers getting paid in BTC, because their central bank clamped down on USD inflow. They also didn't want to be paid in the worthless local currency. [1]

- Remittance shops in Hongkong are using BTC to settle remittances by batch. Buy and sell to the last mile instantly, no exposure to volatility. This gives them way better FX fees and faster settlement (30mins vs. 1-3 business days). They pass the savings down to their customers as marketing spend, or they pocket the change to increase profit [2]

- Argentina Central Bank is hoarding USD due to dwindling reserves. So they imposed a $200USD/month cap on individuals transacting with USD. People are flocking to BTC for remote settlement. [3]

- Iran hit with sanctions cant use USD. So they're working on laws to use BTC for settling imports with China. They even issued BTC mining licenses for private companies. [4]

I come from a country, where if you remit more than $10K outbound you'd have to: pay big fees ($200+), suffer bad FX rates, wait for 2-3 days, do a physical appearance at the branch for and pay documents/notarial stamps, sign forms, present and print out government ID's, just to say: "This is my money, I just want to send money to my dad overseas for medical purposes".

December 2020, my mom had received USD in her dollar account. She wanted to withdraw and convert it to help build float for the family business, the local bank didn't have enough USD. They told her it was a 6-week wait, lots of people lined up. Lol.

People from first-world countries have it good.

What a weird comment. There's tons of fraud within the bitcoin ecosystem, and it's also used in a lot of fraud too.

When the alternative is simply just using Proof of Stake and lowering the energy consumption by an estimated 99%, yes, we can be judgmental of how others use energy in this specific case. It's not Bitcoin/PoW or no cryptocurrencies at all, that's a false dichotomy, if that's what you're implying.

Good luck with that. The bitcoin core folks can't even agree to change blocksizes to increase transaction throughput. Switching to PoS is highly unlikely.

At that rate and assuming 4tx per second a single Bitcoin transaction consumes 165kWh. A Tesla battery is bit over 50kWh. So let's round that to 3 full charges of Tesla battery.

That's 350km/220 miles of range per charge. In total 1050km or 660 miles of driving.

So basically if you want to transfer money and the recipient is closer than 660 miles from you it's more efficient to just get a bunch of bills, drive there with a Tesla rather than send a Bitcoin transaction. Or alternatively 330 miles roundtrip. For each single transaction.

It is hilariously inefficient system. It is literally better to drive a full car and give things physically than use Bitcoin.

A small addenum: Visa apparently uses 146kWh for 100000 transactions. Coming at 1.46wH per transaction. That can drive a Tesla for 9 meters (0.4 seconds of driving at 80km/h) or alternatively keep a nice led lamp lit for an hour. And that includes everything the company does, not just the actual transaction but the upkeep of their offices etc divided by the amount of transactions they perform per year.

EDIT:

Apparently on 2020 it was 741kWh per transaction in practice and/or I made a tiny error in my calculation. Either way it's even better!

https://www.statista.com/statistics/881541/bitcoin-energy-co...

That simply increases the ranges so that it becomes a 3600 mile trip. Or 1800 mile roundtrip.
