> from facilitating scams and other illegal activity
The same was said over and over on the nascent days of the internet, about how it facilitated anonymity so easily and how it would be used by criminals.
> by stealing CPU cycles
Difficulty in bitcoin mining is raising all the time (because of the competition among miners). This is why nobody mines nowadays with CPUs or GPUs but with ASICs. The fact that some sites are trying to achieve some decent mining hashrate by pulling the amount of visitors of a website is a naive move that will soon be off-set by even more raising levels of difficulty. Soon this will not be profitable at all, even if your website was the 1st in Google's page rank.

I like that skeptics raise this point, because:
1) The cryptocurrency mining industry is the fastest one to chase energy-efficient solutions. As soon as a device consumes less electricity, it's adopted widely because of the huge incentives to do so (e.g. CPU->GPU->ASIC).
2) Compare the electricity spent by the entire banking industry with the electricity spent by the entire crypto-mining industry. Now guess what's more efficient.

There's 2 things I want to say about this comment: 1. Those accusations were not wrong. In the same sense that we have pretty clear evidence that a lot of the value injected into bitcoin and stored there is via money laundering. 2. Unlike proof of work currency blockchains, the internet clearly delivered and had no direct theoretical challenges to its very existence that people subsequently and fervently denied. Proof of work is a bad idea. It's been discredited. It doesn't do what people thought it did. And it's MUCH too expensive to keep doing.
- siwatanejo 9y agoProof of Work is the only way for people to transact in which they don't have counterpary-risk problems before transacting. Before PoW was invented, there was no way of doing this. Now, thanks to layer2 technologies, PoW will start becoming much more (orders of magnitude more) energy efficient. How is that a bad idea? Make something possible, and later make it sustainable. So long as there's demand for that something, then it's a good idea.
- skybrian 9y agoThere are two sides to a trade, and typically Bitcoin only handles one of them. Buy some food with Bitcoin and it still might taste bad or make you ill. Even for purely financial transactions, any kind of loan or investment still has counter-party risk. So even if a crypocurrency worked perfectly, it doesn't solve very much.
- siwatanejo 9y ago> There are two sides to a trade, and typically Bitcoin only handles one of them. Buy some food with Bitcoin and it still might taste bad or make you ill. You have this same problem with any form of money. The problem I raised is counterparty-risk when holding your assets (before transacting). > Even for purely financial transactions, any kind of loan or investment still has counter-party risk. Yeah, that's why maybe loans should have higher interest (right now, the low interest is artificial, because the bank is really making more money from the fact that it's working as a fractional reserve, not from the interest it gathers from loaning you money). > So even if a crypocurrency worked perfectly, it doesn't solve very much. It solves just one thing. Granted, it's not a silver bullet. But there are never silver bullets. Every single invention that humanity achieves, just improves the world a little tiny bit. Cryptocurrency does this as well.
- wpietri 9y agoIt does not solve anything. It's true that cash and bitcoin both avoid a narrow slice of counterparty risk. But that's not a whole problem, just part of one. As a currency, Bitcoin is an abject failure. Even big proponents admit that: http://avc.com/2017/08/store-of-value-vs-payment-system/ http://avc.com/2017/08/store-of-value-vs-payment-system/ Bitcoin made no practical dent in existing legal financial transactions because it's not better for the great majority of use cases.

- infinii 9y agoIt always puzzles me when people point out that cryptocurrencies are used for illegal activities. Cyptocurrencies were not designed to facilitate illegal activities. Yet every fuddite makes it seem so. Every single fiat currency in the world is/can be used for illegal activities. Do we discard them? Care to wager which currency, USD or BTC; is used more for illegal activities? No, I didn't think you would. But media and fudders will repeatedly point out that it's cryptos that are used to transact illegal things.
- spookthesunset 9y ago> The same was said over and over on the nascent days of the internet Do you shysters read from a script or something? Is this the counter argument you guys always use to try to squelch criticism? Bitcoin is more than 10 years old. That is ancient in tech. It has yet to be used for anything besides an excellent vehicle for running scams.
- hackinthebochs 9y ago>Bitcoin is more than 10 years old. That is ancient in tech It's also a blink of an eye for a paradigm shift.
- Scarblac 9y ago> If you can invent a reliable alternative to proof-of-work distributed consensus there is a multi-billion dollar opportunity there. But Bitcoin only does 7 transactions per second. You can't say it's an alternative to something extremely larger.
- adrianN 9y agoThe efficiency of mining on CPUs doesn't matter if you don't pay for the electricity.
