Whether we teach kids or not, it is certain that bitcoin is the future and the future are our kids.
Their is no stopping bitcoin. Sooner or later, cryptocurrency will be taught in schools even in primary levels.
Cryptocurrency is something that is too difficult for kids to absorb because it is not like regular subjects. I do not think in the future cryptocurrency can change the whole of this world, when it starts outdated and is restricted to the level of development, meaning that it will end.
