Pretty smart to leave bitcoins for your children because that will make them rich and they don't have to worry about taxes or anything. But maybe it will be for nothing because bitcoin may always go down and maybe another coin will become important.
Bitcoin has a big future ahead and other cryptocurrencies i think has a long way to go if they want to overcome bitcoin. Yes, it is possible but i don't think it won't happen in the near future. Much better if we earn our bitcoin and save it for the future of our family.
I am indeed believe that bitcoin has a huge future kind of cryptocurrency. And speaking of a better future it is not bad to start save bitcoin for our children, for our future. Either it will make us rich soon or not, I would prefer to start saving bitcoin for some personal reasons. Though bitcoin value was inconsistent well I still believe it's potential to make the life of my children easier.
