Without to be paranoiac, I think that finding a weakness on ECC such secp256k1 and stay anonymous in a "safe place" is near impossible in this hyper-connected world
After this discover, billions of dollars will be instantly at the fingertips of the researcher(s) and at the friends well informed (notice that the most probable issue is that the price of bitcoin will drop to zero).
NSA, Armed forces, governments,research consortium,mathematicians, big tech societies, will deploy all possible technicals and humans resources to obtain the study (and not only the legals ways

). just to insure that if secp256k1 is broken or partially broken means that the others curves (like the very close secp256r1 widely used) aren't compromised too.
Today every secures communications (website certificate, https, banks,stock exchange, cryptocurrencies, army, administration... on internet use ECC.And a lot of our economy is based on the security of the communications.
The cake is simply too big...
Lets not bother the men in black just yet, I don't know who else is using secp256k1 besides bitcoin, but I'm sure the military or gov organization is using it for their communication.
When we talk about bitcoin, it would be a bad idea to publicly announce the weakness because it is open source and fixing it would be nearly impossible, publishing weaknesses about other curves, well that would just notify everyone in the world that there is a weakness, that would be a good thing.
Besides DLP already has a solution called kangaroo, I am trying to understand how it works because I never finished high school, therefore I don't understand the symbols, signs, mathematic terms used in the algorithm, lol.
Ps, militaries and governments use private curves with parameters unknown to the public, internet communications also work through hash functions, cryptocurrencies are the only targets of exploit if there is a weakness in their used curves.
