Unexpectedly participated in a class action lawsuit in the USA en ru

Recently, I unexpectedly encountered a justice system in the USA.

• In 2017-2018, when there was a crypto boom, I invested a little in a mining startup: I purchased their tokens and one hardware unit.
• The startup went up and began to build a mega farm, but it didn't work out — the fall of Bitcoin coincided with their spending peak, the money ran out, and the company went bankrupt. It's funny that a month or two after filing for bankruptcy, bitcoin played back everything. Sometimes you're just unlucky :-)
• I had already written off the lost money, of course. I acted on the rule "invest only 10% of the income you don't mind losing."
• Since everything legally happened in the USA, people gathered there and filed a class action lawsuit.
• I received a letter stating that I would be automatically among the plaintiffs if I did not refuse. I did not refuse; when else would I get an opportunity to participate in a class action?
• Everything calmed down until 2024.
• In the spring, another letter came: "Confirm the ownership of the tokens and indicate their quantity. We won and will share the remaining among all token holders proportionally, minus a healthy commission to the lawyers."
• But how do I confirm? More than five years have passed. The Belarusian bank account is closed, the company's admin panel is unavailable, and there was no direct transaction in the blockchain—I paid in Bitcoin directly from some exchange (although it is not recommended to do so).
• I found an email from the company confirming I bought tokens (without the amount) and printed it as a PDF. I attached it to the application with screenshots of the transactions from the exchange for the related period. I gave the address of my current wallet, where these tokens lie dead weight. I sent everything.
• Today, I received $700 in my bank account. Of course, this is not all the lost money, nearly 25%, maybe slightly more.

What conclusions can be drawn from this:

• Sometimes, you just don't get lucky in your business.
• Keep all emails. You never know what and when will come in handy.
• Class action lawsuits work and do it in an interesting way.
• Justice in the USA works slowly but, apparently, inevitably and unexpectedly (for me) loyally to minor participants in the conflict. At least sometimes.
