E*Trade Warning for Crypto Investors

I opened an ETrade account last year to hold short term treasuries (holding cash to cover tax bill). April rolls around, I go to sell the treasuries to cover taxes, and my account gets locked. I call them, they ask: - how much crypto do I own? - which coins? - do I stake/mine? - where did I buy the crypto? - how much do I trade crypto? - they demand a tax form from a US licensed exchange showing all my trades It’s an extended KYC check, so I need to answer or else I don’t get my money, plus a SAR filed. Self custody as much as you can, everyone. The banks and government are getting too uppity.
