Thanks for the input. They really messed up how to handle this. Back then when BTC was $32, Coinbase was the only player in the game.

Totally, maybe they think I'm being investigated. lol.

Yeah, that makes sense. I’m in California.

Yeah, I did that ages ago.

I have Electrum and Exodus, both desktop wallets. I transferred my BTC like always. No extra info from them, just can withdraw but not trade anymore. It might be my bank or something, but I’ve been with them for 2 years.

Been using Coinbase since Bitcoin was super cheap. Just moved some BTC to my wallet like usual. Now I log in and see my account is restricted. What the heck? Support says I can only withdraw my coins but can't do…

Wait, are you saying no isogeny can exist at all? That's not right. Sure, there can’t be an isomorphism, which is like a degree-1 isogeny. But other prime degree isogenies can exist even with different J-invariants.

I got a situation here. I have two elliptic curves, E1 and E2, both over the same finite field. E1 is pretty secure, prime order, large embedding degree, not pairing-friendly. E2 shares those traits but totally…
