Carrousel7956 Every CEX is a point of failure.
Just accept this instead of trying to get around it. Onboard with a CEX even if it is KYC - Fiat into crypto; most CEXs don't care if you move small volumes of crypto into self-custody, so over time you could easily trickle significant amounts of money out across various exchanges. Data aggregation of crypto is still poor, and serious work would be required to track it all down.
I am unsure what you are planning to do with it, but a few thousand dollars is easily enough to pay more most services annually (say email, VPN, etc.). If you're "trading" crypto, there's not point being in self-custody land.
