Safely store BTC w/o HWW

Due to the recent events with CC and the war on BTC, I am trying to find a safe way to store my coins. I’m by no means an expert In this space, just doing my part to stack sats. I am a CC user and have moved my BTC to strike as I wait for a new HWW which arrives tomorrow.

Apparently tomorrow there is a potential chain split In BTC or something like that and I want to make sure my coins are safe. Outside of an exchange, is there a place where I can import a dice rolled seed phrase somewhere to secure my coins?
