It is a personal responsibility to keep your bitcoins safe by yourself, not under the trust of someone, or an exchange. Self custody is risky but it is not something any bitcoin investor will not be able to do if they pay close attention to security tips and updates as they change and are shared on this forum. It is easy to forget the importance and let your guard down at some point when you are hodling, but it is always important to remind yourself that letting your guard down even for one moment can lead to loss and severe regrets.

Guard your bitcoins with the consciousness that loss to criminals is not impossible.
