ASICs have a hardware hash/watt race issue that GPUs (with memory hard algos) don't have (older GPUs are actually more ROI efficient). GPUs are also easier for a wider range of people to get with a much lower cost of entry. I'd argue that GPUs are still a better solution than ASICs, but this is an age old battle full of opinions. Bitcoin hardware isn't worthless for any other application, any other sha256 based netwo…

What's that attack cost supposed to represent? Just the electricity? Seems like a misleading comparison, to get into a position to be able to do this you'd need significant investments in specialized hardware for the likes of Bitcoin and Ethereum. I've seen estimates of multiple billions of USD. And keep in mind that should the attack be discovered, which with coins running on open ledgers seems likely sooner rather…

The site details the cost to attack using rented 3rd party compute. For some of the coins, there is enough compute out there that can simply be rented with no upfront capex/opex involved on the part of the person doing the renting.

The problem with that is that the rental market is an open bid supply/demand market. The second you start to rent out enough hashrate, the rental price also increases. That isn't factored into the numbers.

You are correct that the cost of capex/opex for ETH/BTC is in the billions, which is also what makes them so secure and attacking the network would also destroy the network. It is a brilliant feedback loop.

Monero has a pretty active development community. If GPUs ever get close, they'll change RandomX.

You can't mine Monero currently with GPUs? I haven't mined in years and I know they changed away from the cryptonight algorithms but I used to mine on both CPU and GPU.

Oh, yes. Yes you can. Go load xmrig and enable the opencl / cuda extensions if you don't believe me. Example output:

     |   CUDA # | AFFINITY | 10s  H/s | 60s  H/s | 15m  H/s |
     |        0 |       -1 |   1710.7 |      n/a |      n/a | #0 01:00.0 NVIDIA       GeForce RTX 3080 Ti

51% just doesn't feel like a meaningful threat model when governments can instead prevent exchanges offering monero pairs from accessing banking services in their country/currency.

That's already the case with most countries and exchanges. A lot of monero trading happens on p2p exchanges which don't tie themselves to any country.

The next natural step in that direction would be banning all exchanges from banking in hard money.

It would push people to p2p, at the expense of cryptocurrency prices. Big win for the environment and people hoping to use crypto as currency. Big loss for people holding for speculative gains.

I feel bad about this because I wrote an article[0] about how to hide Monero miners on Linux systems. Sometimes I ask myself if I should unpublish it as probably some of the criminals doing this type of attacks found it helpful. [0] https://alfon.xyz/posts/hiding-cryptominers-linux

How much search engine traffic does that article get?

I don't know exactly how much traffic it gets because I don't do any type of tracking.

I frequently receive emails from anonymous persons asking for help and even some of them are willing to pay me to set up it for them… so you can imagine what these last ones are using it for.

It's been over half a decade since that stopped mattering, for me. I've bought goods and services directly with Monero plenty of times. I've paid invoices that the merchant put in Bitcoin, while using a third party to pay in Monero, which the third party then paid in Bitcoin. Now in the 2020s I can swap Monero directly to SECRET network, a Tindermint/Cosmos blockchain where all smart contract executions are private (…

It's certainly going to matter come tax season to businesses which are/will be forced to convert Monero to local fiat. > I've bought goods and services directly with Monero plenty of times.

US businesses and persons pay tax in income no matter what asset it was received in, and report capital gains or losses as well upon liquidation into another asset such as fiat

There is nothing unique about crypto or monero in that regard, what did you have in mind?

What are advantages of doing all those steps using Monero instead Fiat? I understand that you can hide your trances but if you buy legits things, who cares?

to the edited version of your question: > What are advantages of doing all those steps using Monero instead Fiat? I understand that you can hide your trances but if you buy legits things, who cares? I had a balance of Monero. It was convenient. Online payments are a lot easier when you don't have to fill in a bunch of information, what "steps" were you imagining? I didn't have to go get Monero, I had already accumula…

Two decades ago actually, Bitcoin launched in 2009.

Thanks. That's what I thought, good to see it's still possible.
