Not a US citizen — lost ~$700k crypto (LastPass). Class action, contingency lawyer, or walk away?

I’m not a US citizen. I lived in the US for a few years for a master’s degree (2008–2012) — not sure if that matters for anything below.

I know this is really stupid — hard lesson learned: I kept my seed in a LastPass Note.

I started receiving crypto in 2015 as a freelancer. In total it was roughly ~$80,000 USD of earnings/savings into crypto over the years — not an overnight windfall. The stack grew as prices ran up, and by the time it was stolen it was worth around ~$700,000 (what people mean when they say I “lost $700k”).

On-chain it didn’t leave in one transfer; it moved through tons of tiny hops, so tracing was miserable. I’ve already reported to US law enforcement (e.g. IC3).

There’s a LastPass class action. I’m not sure I’m eligible as a non-citizen with old US ties, or whether joining is worth anything.

What would you actually do?

• Join the class action — or waste of time?
• Find a contingency lawyer vs LastPass (no upfront fee)?
• Stop and accept the sunk cost?

Not asking for formal legal advice — just what you’d prioritize. Thanks.
