Is it safe to hold all of your BTC on one address in cold storage?

The advantage is obvious. You have all your BTC in one address meaning you would be actually able to memorize the private key and have the encrypted metal stamped version of it in some safe in case you die and want to leave to someone else.

But is there a threat posed by this Bitcoin collider that someone stumbles by chances exactly into your address?

No.

If you used a well written wallet that did a good job of generating random private keys, there is no threat posed by Bitcoin Collider.

It is safe to store all your bitcoin in one address.
It is almost impossible that someone will stumble into your address by chance as there are 2¹⁶⁰ possible addresses, which is more than the amount of sand on earth squared.

This kind of situation happen that chances so less. Means mostly it will never happen but then  also if you want security, you can transfer your BTC in another address after some months of period means after every 6  months of period you transfer your BTC in another address.

I think it's safe, if your private key is strong enough.
