Will I be OK personally if it goes to 0? Yes.
I admire your level of enthusiasm toward Bitcoin and the risk involve. However, it is not possible for Bitcoin to crash to 0 prices not even now that the major investors are the institution and organization.
Now that I have one Bitcoin, I need to cherish it. My next move will be transferring it from an exchange to a cold wallet (Ledger, perhaps?)
Ledger is the worse recommended hardware wallet but you need to understand how to secure it and also avoid the human error which could expose the wallet to online theft.
In the meantime, congratulations on accumulating a full Bitcoin which is the dream of every crypto enthusiast.
