My first thought was someone they tied a blockchain transaction to my name and then traced it backwards. But they also knew my ETH and BTC balances, and date the account was opened. You might be able to figure out the open date by looking at the blockchain but I could never determine how they would know balances for two unrelated cryptos without some kind of coinbase compromise.

There's tons of options. Malware, evil maid, shoulder surfing, email compromise, improper disposal of printouts, prior phishing attack, accidental disclosure.
true, I can’t rule those out entirely. I access via iPhone to limit attack surface area, the info was never printed, present in emails, or disclosed to 3rd parties
