If we continue to recount all the things we spend money on instead of investing, we will continue to live in regrets. First of all, for students in high schools and colleges, the main focus is to acquire basic education relevant to their field and at that level it is best they concentrate more on learning and saving. Introducing bitcoin investment and any other forms of investment will be a kind of distraction to them. Once a child begins to make millions from his investments in bitcoin, formal education will make little or no sense to him and remember, no education is a waste. Bitcoin investment isn't fading away anytime soon, they still have a long way to go. Money spent on smoking and other things not relevant can be saved while still sorting out their academic works.
I also do not support encouraging students to invest in bitcoin because it is not a mandate or something they should care about. What they need to focus on is studying hard and trying to achieve the best results because that is their future. Regarding whether they have living needs or bad habits such as smoking or drinking alcohol, it is best for them to limit or stay away, and use that money for things related to their studies, not for investing.
But honestly, I don't see any connection between investing in bitcoin and smoking. Just like some of us will like to go drinking with friends on the weekend after hard working days, some will choose to picnic with family, watch movies...should we give it all up and save to invest in bitcoin?
