A great gift idea for your grandson who likes Bitcoin could be:
1) A physical Bitcoin: you can purchase a physical Bitcoin coin from various online platforms. This would not only be a great way to introduce your grandson to the idea of a physical representation of his interest in Cryptocurrency, but it would also serve as a great collectors' item.
2) A beginner's guide to Cryptocurrency: Since he is interested in Bitcoin, a beginner's guide that talks about the basics of Cryptocurrency would be an awesome gift. There are many great books on this subject that he can explore.
3) A crypto-themed hoodie: You can get him a hoodie with a Bitcoin or Cryptocurrency phrase on it. This will not only keep him warm but also show support for his interest in Cryptocurrency.
4) Bitcoin socks: if your grandson loves wearing playful socks, Bitcoin-themed ones will make a great addition to his collection. These are readily available online.
I hope this helps and your grandson has a great birthday!
