I have to say I'm a bit jealous I didn't think of this earlier. It's a fantastic idea.
& it's literally the type of gift that keeps on giving. The potential your brother has with this gift is endless I believe. Much better than any material item you could've gotten him.
Marketing BTC by saying, "I got BTC for Christmas" is a genius idea. Most people will ask what BTC is & that opens up the door to you having the opportunity to explain to them about Steemit & how BTC integrates into that.
Absolutely brilliant idea! I will surely follow your brother to see his progress on Steemit & help where I can with Resteems & upvotes.
Good post Sir!
