Even at a basic level, the promotion of bitcoin is very important. Bitcoin has not been released long ago. still has high potential. People who are children today will be company managers or economists tomorrow. Maybe they will be president. It is necessary to teach the technology of the future to future generations.
If bitcoin or crypto is taught for elementary level classes in my opinion it is impossible because elementary level children's minds will not be able to accommodate lessons about bitcoin which I think will be ignored because it is difficult for them to understand.
and what I know is that applying crypto or bitcoin lessons only high schools and universities tend to be easy to understand and will be directly involved, and what we see is the growth of bitcoin that millennials like today because it is taught in high schools and universities which are very easy to understand and in demand by them.
Indeed, elementary is still not the right place to apply knowledge of bitcoin and crypto, only young college students have enough knowledge to understand crypto and bitcoin issues but maybe the instructors need to systematize the knowledge they have when in my country, the instructors are just understanding too little about bitcoin. My brother even said his teacher requested to download mining apps on his phone then recommended it to many others for a commission, this mistake can actually cause data loss and reveal a lot of personal information, which is quite dangerous
Children get information much faster than adults. My cousin started learning informatics from second class at school (according to pupils program). Now she is in forth class and she already familiarized with basic programming modalities and can write a program. Think, it's really time to start learning about crypto and blockchain technology at school (maybe not at the primary school, but it must be obligatory at secondary school).
