There are many other things to discuss with your children or grandchildren over dining table and that too if you want to discuss bitcoin itself then you will be fortunate enough for sure to discuss it with your children and your family. Bitcoin is here for the long run and it just recently completed its first 10 years of existence and there isn't any doubt behind it completing another 10 or 20 years for sure as governments are favouring it, legalizing it, it's becoming simpler to use bitcoin in day to day life so there is no reason why it will be having a deadly future.
