Saving bitcoins to your decendence might be a very smart move if you are already providing enough money for yourself to have a decent life , but i don't think that the inflation problem will stay forever and it might be corrected rather sooner than later to ensure a stability among bitcoin users . So you should start executing your plan in order to get as much profit as possible .
I donot think this will happen ever ,cause the price are not stable for 9 years and it will not be in future.
So yeah if we keep saving a littile bitcoin for our next generation it will be great for them when they grow up.
and I really hope by that time bitcoin will be 50000usd.
