Yes indeed! It's exactly for purposes like this that I thought it would be a great idea :)
I regret not asking for more things whose value was likely to increase over time when I was asked what I wanted for Christmas in the past :P
This has the added value of also providing some education in something that will only become more influential in their lives: Blockchain technology.
Hope you'll do it! Perhaps you could make a post about it explaining like you did here how you think it will be a great gift for the future :) maybe it will even pay back a bit of your purchase!
