Nah, it will be fine. You are not the first person that thought of this in the last 16 years.
Just wait until you discover monero.
Since the remaining supply will take approximately 115 years to be created, this theory isn't something you shouldn't worry about.
You won't be around by the time we might perhaps face a security risk.
