We are lucky because we are of age to know and understand what bitcoin is at this time when the value of bitcoins is still expected to increase not like our children who have no idea and it may be too late for them to make any gain from bitcoin when they finally know about bitcoins if you leave them.
Why you are so optimistic that in the future the price of bitcoin will not make any gain of profit? the volatile characteristics of bitcoin price will always attached to the bitcoin, so if your children are traders bicoin in the future, they will still be able to gain earning by doing short trading. I hope bitcoin will always benefit for us all the time.
