Keep crypto on ledger or exchange?

I took my coins off binance about 8 months ago and all I keep reading is everyone getting hacked and losing everything left and right when they take full ownership. I did not update ledger since the issue where people were have their crypto taken with one of the updates(is it even okay to update now?) but I’m thinking on putting my crypto on kraken with plans to sell mid 2025. If I do keep my coins on ledger is there and simple rules I can follow to not get hacked in the meantime? Having a simple list from the experts would help a lot of others as well, build our crypto community and prevent us from losing everything. Thanks so much.
