Just because someday it could be cracked doesn't mean it will be cracked you make as if everyone out there is gunning to destroy anonymity technology.
Sorry but if it takes 10 or 20 or 100 years to be cracked why would I really care? In that time I would likely have moved from one address to another and traded into and out of XMR or another CN coin or I would in the worst case be dead.
Anonymity has 0 value to me once I am dead and gone from this world.
With enough time and resources any thing can be cracked.... No surprise there lol
Why risk it when you don't have to? There are designs that don't risk it.
You can't predict when the crack will occur. It could be within a year or 20 years. But 100 years is much less likely.
Why?
It is simple...
I never put all of my eggs in one basket. Should your hypothetical situation come true one day...I could care less as the likelihood of me being exposed to that sort of attack vector is very small. And if I lost coins or anonymity oh well.
Personally I can see people wanting anonymity for a short period of time and doing it in multiple iterations where there would be little to discover if say you traded XMR for LTC outside of an exchange...now how do you track that transaction?
Right you can't necessarily link them together trivially nor with a super quantum computer down the road.
You are clearly vested in Cryptonote and the price is lower than when you bought. Because your logic doesn't make any sense.
Why would anyone diversify into more risk when they can choose designs with less risk. Surely there will plenty of CoinJoin-like designs to choose from. DRK would not be my choice either, because it is not well modeled with a white paper.
Also Cryptonote has severe inefficiencies too, such as you can't maintain unlinkability if you run a lite client.
P.S. don't be led into false security by cross-chain transactions. It can actually increase your risk of de-anonymization.
Edit: and as a developer, I don't want to be responsible for millions of people being subjected to State wrath some years from now.
