Stormrake - Dodgy custody of Bitcoin

I thought about buying some Bitcoin and I spoke with one of the pushy brokers at Stormrake. I changed my mind when they said they charge a 1% custody fee to look after my Bitcoin. It's not a real custody service, as they hold it on their own balance sheet. It's mixed in with their own holdings and other clients' funds. I thought custody was a service offered by reputable groups, not brokers. Isn't this what FTX did in the last correction? That's the whole point of independent custody. I'm not sure I trust them, so I'm looking at other options. What do you think?
