I would introduce my child to the concept of terrorism by first showing him the good done when there exists peace.

People are unhappy because they have forgotten the meaning of commitment.  They always wander around without committing themselves to a particular thing which renders them aimless and makes them lethargic.

Now that is a question which swirls around in everybody's mind using bitcoin atleast once. I think doing so is disastrous as there's a lot of stress involved in trading off the bitcoins. Plus one has to have the eye to closely follow the trend and to use their expertise to trade or sell off which itself is a very daunting task. So first give it a dry run for a certain period of time and if all goes well then it might be that you're good to leave your job and immerse yourself into the world of bitcoin.

Saving bitcoin for our children is a very good innovative as bitcoin is one of the world popularised monetary system. Bitcoin shows a trend of increasing continously so there is no problen of relaps or loss. It will also ensure that we introduce the future generation out children to the online monetary system. Bitcoin can be indefinitely saved without the worry of theft or cyberhack so I think saving up in the form of bitcoin is the best way to ensure our children's well being.
