1 btc in my country is huge enough, and it will be more huge in the future seeing its price continue to appreciate year after year.
At the moment I have not thought about passing BTC to my son. Currently, I am focused on providing the best education for my children so that they are able to compete for life. This means that he will not be distracted from what I have inherited for him. Whatever the number, if the generation you give is able to manage well, I think it will continue. Although we also do not have certainty about its value and its durability as a digital currency in the future.
