Better replace forcing with motivation. It a perfect instrument to make someone do something. For kids, forcing = resisting. It will end with you being more pissed of and angry, but the kid will still win

And don rush on teaching kids investing. They learn better if they can be involved or get any experience.
It's hard forcing a kid to do a thing, from my little experience I discovered the more we force kids to do things the more the try to resist. If there is enough motivation as mentioned they will do things even without being forced or complelled to do so.
It's a good thing if your kids decide to venture into BTC and blockchain, but as a parent always make sure you monitor them just to be sure that they are doing what they claimed to be doing online.
It is just very unfortunate that most times the young have the potential to be attracted to the negative side of Bitcoin because of the potential for quick gains and profit. In a corrupt society, many young persons are already involved in dubious activities or looking for the next dubious activity to get involved with to get quick cash. If your children are not raised properly in the right moral standards and monitored to ensure that they keep those standards and do not become influenced by their friends, they will be one of these children we do not want our children to mingle with.
Poor upbringing contrubutes to children's misuse of technology. There are parents who only communicate with their kids when they wànt to scold or send them on an errand. This kind of scenario may make them venture into abstract things and stay in high pretence. If parents can be more involved in their children growth and development they will be nothing that will be hidden.
