Discussion ongoing in
another thread about Monero scaling.
Let's break this down into chances.
...
All of anything ever is for sale to the highest bidder! The higher they have to pay, the more value I feel comfortable placing into what they're paying for. Of course there is a limit to which I'd trust anything .. but I can say right now that I'd be fine buying goods under $10 dollars right now with CN ..
I already said one-time ring signatures are an improvement,
except they come at the cost of defeating the mini-block chain, which is the only way I can see to scale to micro transactions and remain decentralized (assuming you want new mining nodes to be able to pop up, download the block chain, and leave the network at-will to guard against IP blocking by the authorities, etc...).
As for "chances", note that if you have 1 in 1000 chance of losing your anonymity for any single transaction or mining share submitted, then after 100 of them your probability of being anonymous has dropped to 1 in 10. Now I realize this doesn't take into account that access to your ISP or upstream router is not a random trial, so the point is in some respects specious. My point is that if you are talking about hiding my wealth from the G20's plan to hunt down and confiscate all wealth, then I'd rather something the NSA can't see easily and hackers can't see with some effort. Suppose you are in a nasty divorce, and your ex (or her attorney) wants to get revenge on you so they hire some hackers. That is not so rare. And there are many scenarios that overlap.
And if you are targeting business usage, then the extortion and espionage value of hacking it increases.
