There's a bounty of $100M (at the very least) for cracking 256-bit (128-bit strong) elliptic curves. It's called Bitcoin :)
So if they're broken - we'll know that very, very fast.

not true - the public blockchain means that cracking the encryption is only a very small part of such problem. You also need to convince all the other peers that you cracked it first
Because Bitcoin IS cracking encryption - bitcoins are assigned by doing exactly that.
In Bitcoin, a private key is usually a 256-bit number (giving a key length of at least 512 bits)
On the other hand, I'm sure all the MTgox customers will be happy with your assertion that their $450 million of missing/stolen funds allegedly stolen straight out of the MtGox hot wallet over time, beginning in late 2011. are actually still safe. Not sure they'll agree however.
I'm complaining there is no STANDARD & SECURE way to establish secrets (unlike say AES or Rabbit). That's not quite the same thing. Nearly everything has been designed to fail from the very beginning. Or are you saying you still trust "the experts" after everything that's happened?
Curve 25519 does not meet the ECRYPT recommendations of a min keylength of 512bits for Ellyptic Curves https://www.keylength.com/en/3/ Curve 25519 at 128bit provides:Very short-term protection against small organizations Should not be used for confidentiality in new systems
->OpenSSL since version 1.1.0
Probably the very worst example of an implementation you could give. OpenSSL version 1.1.0... Really????
