I think a JISA (if you are in UK) with Vanguard is probably the best way to go with things - given the amount of time you'll have it open for you'll most likely see fairly decent returns. The Vanguard Lifestrategy funds get recommended time and time again - basically pick your risk level / fund and then it's pretty much set and forget. I guess there's nothing stopping you from putting a small amount into crypto but I certainly wouldn't want to bet my children's future on it.
