technology will continue to develop over time. so if we give our baby satoshi bitcoin now and keep it in a hardware wallet. I'm afraid that in the future bitcoin hardware wallets are outdated and irrelevant to the technology of the time. 18 years is a long time I am also afraid that at that time bitcoin was not as valuable as it is now. I better sell Satoshi Bitcoin to buy gold jewelry for my baby.
Yes you are right. Saving satoshi as a gift is not highly recommended because we are not sure if how long the does the crypto currency lasts. Whether it will be legalized in the future or it will be banned by the governments because using crypto currencies has a lot of disadvantages that they may use as a reason for crypto currency to be removed.
