No I do not think that youngsters or anyone should go all in on bitcoin because firstly it's prices keeps on fluctuating which means that if there is a chance of increase there is equal chances of decrease in value. Secondly it is not centralised form of currency which means it's not regulated by any government or bank so it's not a good option to go all in with it.
Yes I agree with you. Bitcoin is not all the life. It is the financial support for a family and there are lot of more things in life than earning money all the time. The Youngers should give time for their social activities and to their friends. I suggest the Youngers should know all about bitcoin and start their activities in bitcoin but not all the time. The society and community is more than that. They should follow their elders the most.
