Last day, i talk to my sister and tell her about the crypto currency. I explained on how it works and how to get profit in this crypto world.
She is 13 year old grade 8 student, she said to me she's not ready and only her focus in study in school.
I think 18 years old and above.
The age of 10 could be a good starting point for the children. If they're below the age 10, they won't be able to understand what bitcoin is. It's easier for them after they are 10 years old.
