I understand that Bitcoin would be a great gift for anyone. I saw many peoples send gifts in form of crypto. The OP of that thread takes it to another level. It reminds us that one day Bitcoin will go to the moon. Who knows, this 100$ worth of Bitcoin will bear baby's education expanse in the future.
From getting inspiration, I also gave a gift worth 100$ in form of Bitcoin to my brother on his birthday. He is now doing his M.S.C degree in Public Health. He has always had a passion to get a Ph.D. degree. I hope this small gift will help him to reach his goal.
He doesn't have any wallet or exchange account, so I opened an exchange account for him and set up all the settings. I teach him some basic things in the crypto industry (those will help him to secure the account). I also suggest him to put his Bitcoins in staking, which will give him some APY return in long-term investment. The staking method will help him to grow his Bitcoin. I also suggest him follow the SIP strategy, if he finds any interest in the crypto industry then SIP could be a better option for long-term investment.
What confuses me here is Your brother is a a college student meaning he has a capacity to learn crypto and make His own wallet, then why on earth you need to create for Him? you should have let him learn about crypto first before giving him this fund , because in some cases if you both has disagreement in future ? you can just simply take back that Bitcoin from him because you are the one who created the wallet in which this action makes no sense at all, let him have His fund and not that you are the one who will handle it.
Take it easy, there is nothing wrong with giving a gift. Anyone can gift that to anyone.
Since his elder brother is studying for M.S.C degree, he is quite mature. After receiving the gift, he may be interested to know more about Bitcoin and transfer the coins from the exchange account to the software wallet.
He wouldn't be interested in Bitcoin if he didn't get any gift. After receiving the gift, now he will be interested to know about it. And since OP has now realized that the value of private key is a lot, maybe he will explain things to his brother himself.
Of course I would like to thank OP for giving such a gift.
