The benefit of decentralization is not nearly large enough to outweigh the massive costs.
What does this even mean? How do you determine the value of decentralisation and what's its fair cost? Why do people (miners?) bear those costs then?

It means that the only "pro" of crypto over, for example, Visa or Mastercard or Venmo or any other means of transferring money/value is the fact that it is decentralized. You don't have to trust anyone, whereas with Venmo, you're giving a company control of your funds. The cost of crypto vs these systems is that it is WAYYYY slower, not scalable, more expensive in many cases, and requires the use of a massive network that consumes stupid amounts of energy even when it is less than 1% of the size it would need to achieve the dream of replacing fiat currency. It's just not worth it.

You haven't answered the question. How do you determine the value of benefit of decentralisation? If the high costs are not justified, what's the fair cost?
Average Joe may not be valuing decentralisation too high, but it's a different story for WikiLeaks (and alike), who had all their bank accounts frozen, or for individuals/businesses from Cyprus (EU member state, not some Banana Republic), who had seen their money just taken away from them, or for citizens of shithole countries with high risk of hyperinflation - you get the gist.
Other than exchanging physical goods (incl. cash), cryptocurrencies are the only way to transfer value in trustless, censorship-free, borderless manner. How do you put a value on that to say whether costs are justified or too high?

As for speed/costs - cryptos are performing pretty good. Bitcoin seems slow compared to other cryptos, but txs are irreversible and settled in average of 10 mins - this is huge advantage over the traditional means. Credit card purchases are rather expensive (especially for small merchants), buyers' could think they're free, but they're not - merchants pay the fees (and pass the costs to the buyers via increased product price, which also reflect costs of fraudulent chargebacks).

I just made a purchase on Aliexpress, my first payment attempt failed for an unknown reason, tried different card - it went through. Now I only have to wait 1 day for them to verify my payment. Wow, how fast and convenient. I'd be happy to pay even $15 fee just to use BTC if they had such option.

...
Wrong. You only need tokens for decentralised, trustless, anyone-can-participate blockchains. You can have 'private', tokenless blockchains run by authorised nodes.

Actually it is right and you pretty much just admitted it. A centralized and non-trustless blockchain like the one you are describing is completely pointless. You are better off using a database, which would be WAY faster and WAY fewer computational resources.

Private blockchains don't require high computational power (mining hashpower) at all. If it's pointless then why the hell is Swift (and others) spending presumably a fortune to explore/implement blockchain tech? They don't know any better? You want to email them and educate them on the issue?

The problem with going off grid is that mines are the most efficient in cold climate and such climate is not the best for solar panels. You get less exposure throughout the year and have to clear the snow. In warm areas panels are great but mining equipment not so much. A nice idea would be to buy some old, semi abandoned dam in suitable climate and use the power for mining. That's a huge project, but doable if one had a couple million USD to spend.

You don't necessarily need a dam for hydro-plants, and it doesn't have to be super expensive. If rumours about Bitmain's profits are true, then Jihan could easily afford to build his own, small hydro-plant. Check this one, it was built as a community project: http://www.stockport-hydro.co.uk/

There's also geothermal energy (available only in some regions), which is probably the best and cheapest energy source in cold-climate countries.
2504  Bitcoin / Bitcoin Discussion / Re: A whole set of regulatory measures in action on: March 07, 2018, 09:33:58 AM
I can see a time when miners are forced to reduce power consumption during periods of peak demand. Alternatively, they may face heavy surcharges.

My vision on mining vs power plant situation: a company refuses extra clients and income (the power plant) ... no logic

Power Plants are not your average business. They can't increase their capacities in a snap. If demand suddenly goes too high - there will be a power shortage. They need to operate in a stable environment.

Power plants also have strategic meaning, so the local authorities are likely to intervene if something goes wrong.

Blockchain technology itself is overhyped.

Agree.

The benefit of decentralization is not nearly large enough to outweigh the massive costs.

What does this even mean? How do you determine the value of decentralisation and what's its fair cost? Why do people (miners?) bear those costs then?

Furthermore, blockchain technology necessarily requires cryptocurrency, which is something people seem to overlook or not understand. Without some kind of digital token, there is no way to incentivize miners.

Wrong. You only need tokens for decentralised, trustless, anyone-can-participate blockchains. You can have 'private', tokenless blockchains run by authorised nodes.

Betting on blockchain is the same as betting on crypto, and crypto is even more overhyped than blockchain technology itself.

Blockchain-based cryptos are more overhyped than entire blockchain tech? Isn't it like saying "my legs weight more than my entire body"?

* 24-Year-Old Sent to Prison for Selling Bitcoin Without Asking for ID

Only one of these examples is actually somehow related to new regulation proposals. Other 4 are just executing existing laws to bitcoin-related activities.

US City Mulls 18-Month Moratorium on Bitcoin Mining

Local authorities are (rightfully) concerned over excessive power use of Bitcoin mining and it's their job to assess the risk and prevent negative consequences.

Quote
The proposed law was advanced by Mayor Colin Read, who told the Watertown Daily Times that the growth of crypto mining in Plattsburgh "has increased our power usage and put us over our threshold, and it is affecting our ratepayers."

Moratorium could sound like an overkill, but that's still better than having your mining farm invaded by pitchfork mob.

But a change to PoS is a different story. Some time ago I started a thread about that in the German forum. I'm still not convinced - neither to definitively discard PoS nor to support a change now. More investigation about the Nothing at stake problem is needed, in my opinion.

Same here, I'm still on the fence on which is better PoW or PoS. ETH seems to managed to mitigate Nothing at stake risk, but the solution requires use of smart contract so can't be used for Bitcoin.

I'm guessing that if change of PoW is ever going to happen, it will be a PoW/PoS hybrid. You get the best of 2 worlds. If announced in advance (say 2-3 years) then good actors (miners, manufacturers) don't get penalised, as they have enough time to plan their strategies etc. It's not a brilliant solution, as it doesn't solve the power consumption issue, only reduces incentive by 50%, but would make the network more robust and more resistant to government regulations (i.e. ban on mining).

Go on, don't be shy, give a quick summary of what you liked in this article.

All I see is another case of author building a strawman arguments: "Future of Bitcoin depends on global implementation of blockchain tech" + "blockchain tech is superior in every way to traditional systems" and then fighting them. Easy win.

I like how he's praising centralised services such as SWIFT without mentioning they got successfully attacked at least twice in 2015-2016 losing ~$160 millions (iirc). What's even more funny, SWIFT is actively exploring blockchain technology to improve their services.

From the article:

Quote
And Ripple’s technology for cross-border interbank financial transfers will soon be left in the dust by Swift, a non-blockchain consortium used by all of the world’s major financial institutions.

From Swift own website:

Quote
SWIFT tests show blockchain has potential for global liquidity optimisation
Brussels, 13 October 2017 - SWIFT has published an interim report on the proof of concept (PoC) for real-time Nostro reconciliation using a SWIFT-developed distributed ledger technology (DLT) sandbox with 33 global transaction banks, as part of its SWIFT gpi service.

Yeah, journalism at its finest.

... I think there are still many countries where plenty of hydroelectricity is available however cost per unit is high compared to china.

Those countries include Canada and Iceland, who turned out to be not very keen on miners. Local authorities have to take the risk of energy shortage into consideration.

...
That proposal by Cobra was more for the centralization problem of mining than energy Usage. Its a concern as he points out that with such concentrated mining power, an entity like Jihan's Bitmain can cause major upheavals. Though, I think such a scenario is unlikely because they would also be damaging themselves.

I'm aware that Cobra's proposal wasn't related to energy waste issues, but there's no reason we couldn't solve 2 problems with one solution.

As for Jihan - sure, his future profits are heavily dependent on success of Bitcoin, but that's not enough to stop caring about decentralisation. There's always a risk he could get co-opted by MSS (Chinese counterpart of CIA).

The value of bitcoin comes from the securtiy provided by miner's POW. If they decide to shift that security then its a MAD scenario. Not much chance that it'll happen.

How secure was the PoW when gHash pool exceeded 50% of hashpower at one point?
How less secure would PoS/PoW hybrid be?

In my opinion, no PoW change is needed and the energy issue can, in fact, provide a corrective measure for centralization. ...

It could in a way, ie. if countries with the cheapest energy allow mining but introduce cap on its energy usage. That would enforce geographical decentralisation. But the implications of miners having to ask for special permissions (licenses) to mine (which would likely include home-miners) don't sound very great.

...
I think that eventually miners will have to generate their own electricity.
...

Well, that would solve the problem. At the end of the day, it doesn't really matter if BTC mining consumes 99% of global energy, as long as it's not damaging to environment and as long as other industries/individuals don't have to compete for scarce electricity.

And after a PoW change, "CPU/GPU farms" will surely emerge - huge datacenters dedicated to mining. It would have maybe some practical advantages - CPU's don't need a specialized industry and thus mining hardware could be re-used - but no energy-efficiency change at all.

I think you're talking about alternative to SHA256 here, not about PoW alternative. CPU/GPU mining is still Proof of Work.
2513  Bitcoin / Bitcoin Discussion / Re: No country for Bitcoin miners. PoW change when? on: March 04, 2018, 11:00:30 PM

I think the supply of power is still higher than the demand. Miners shouldn't cause any power shortages in Canada or anywhere else.

Afaik, miners still operate on a rather high profit margin, so increase in hash power (and energy usage) is expected. Samsung is entering the mining game, that tells you a lot.

And if the price of BTC keeps going up - so will the energy consumption.
2514  Bitcoin / Bitcoin Discussion / No country for Bitcoin miners. PoW change when? on: March 04, 2018, 10:40:20 PM
With China announcing their intention to cap electricity usage of BTC miners last year, many saw that as a great news as large mining farms declared their interest in moving to other countries (namely Bitmain exploring their chances in Canada).

But now, when Canadians (and others) are starting to frown upon taking on miners, how big of a problem can this become?

Related links:

Is it time we have a serious discussion about energy consumption issues and possibility of changing PoW algo? Already proposed by Cøbra (Co-owner of bitcoin.org & bitcointalk.org), but for a different reasons.

Bill Gates is a distinguished hypocrite, so what could we really expect of him? Microsoft itself accepts Bitcoin at their site, and he either doesn't know or money does not stink. And my take is it's the second. On the other hand, what else could he say? He is a public figure, more or less, so he should be particularly careful about what he says and still more so about what he doesn't say. Obviously, he wouldn't want to sound like he is antigovermental.

Well, not only MS accepts Bitcoin, but Gates himself made few rather positive comments about Bitcoin and cryptocurrencies in the past. That's not necessarily a hypocrisy on his part though. It's not like you have to be 100% for or against something. He could just be noticing both good and bad aspects of cryptos.

But again, the "cryptos causing deaths in fairy direct way" comment was simply idiotic.

Yeah, I've seen that BBC article. This "fairly direct" quote of Gates seemed like a brainfart. If cryptos are to blame for people buying drugs with them - then so is Windows os for allowing them to install wallets, use internet etc.

But to be fair, I tried to find this exact quote on reddit and failed (apparently he wrote it during AMA session). It might have been removed, or BBC misquoted it somehow.

Uphold did their job and withdrawal was successful. Transaction got confirmed long time ago.

I'm not familiar with "airtm" and don't know whether they are legit, but (assuming all the info you provided is correct) they have received your deposit - therefore you should contact them with your tx id and ask why it hasn't been credited to your account yet.

wtf? but i never got any notification that i received any amount or if so that was not reflected on my dashboard, if someone could acces to my wallet and move the btc to another one, it should have been reflected on the movements statement right?

Don't panic about exchange moving funds between different wallets. Sending to deposit address means that exchange (airtm) should credit your account with the same amount of btc, but it's perfectly normal that the funds are moved (either to cold storage or as withdrawals to other users).

You're spot on. If you read the linked article, the first paragraph goes:

Quote
Well, shit. I’ve been watching this situation for a few years, and assuming it would just blow over so we wouldn’t have to talk about it here in this place where we are supposed to be busy improving our lives.

So here he is, a guy that was watching Bitcoin when it was in ~$200 range (or lower), patiently waiting for its imminent death - instead witnessing the price continuously going up, bubbles were popping but new ATHs followed, all while Bitcoin and the very idea of cryptocurrency were more and more legitimised and started to break into the mainstream.

You cannot expect the guy not to develop a massive butt-hurt in such scenario. Especially when he's posing as some sort of money-making expert, who just dismissed potentially the most disruptive concept and, almost certainly, the biggest money-making opportunity of his life.
When his entire identity and reputation gets called into question - he will be doubling down on "Bitcoin is a scam" even if BTC replaced fiat one day (never going to happen btw).

He even went as far as to re-define the definition of "investing" to justify missing the train. Classic coping mechanism.



From the article:

Quote
This separation is important because the usefulness of Blockchain is the primary justification people use for the big dumb Bitcoin lottery.

No it isn't? Primary justification would be decentralisation + network effect. What he did was to build a straw man argument and now he's fighting it bravely. The CancerPill - Bitcoin comparison is simply missed. If it was true - why not creating your own copy of Bitcoin and selling it at say 80-90% of current BTC price? Lets see how far that can take him.

All this somehow remind me of this good ol' meme:
