If you ask how to explain Bitcoin to old people, I will share my experience. I have parents who are not young anymore, in the beginning I explained Bitcoin to them in 2017. I explained to my parents that "Bitcoin is a digital currency, which has a limited supply, and has fantastic value. easy to make transactions in large quantities anywhere and anytime. And the unique thing is bitcoin can be mined and traded ". At least that's how I explained Bitcoin to my parents.
