You're right forcing someone to go into bitcoin investment is not always advisable because the person may end up investing wrongly just like as you said earlier, and of course that's how it is probably when you're being forced into something meanwhile you have not acquire enough knowledge about how it works. and in some cases it might be that the person is not yet ready to go into bitcoin investment but due to how curious you're can make him decide to dive into investing in bitcoin. This is why forcing someone is not always advisable, after giving them the knowledge about how bitcoin investment works we are meant to give them some space to think about it and then make some planning not after giving them the knowledge at same time forcing them to invest in bitcoin No" it never works like that.
Forcing means requiring someone to follow the path you are taking, is that allowed? not in other cases even in investment this is prohibited you can be punished if you force others/relatives to follow it, but if someone is interested in investing we are required to provide education about how good and bad investment is especially investing in bitcoin or better emphasize the risks so that those who want to be interested in becoming investors know exactly what they will go through later. The point is don't force them let them choose their own path.
