10k in BTC and forget?

I'm 55 and retired and have a portfolio I don't need to touch for 20 years. 98% is invested very simply in index funds. I chose to use 2% to play with. I put all 10k of that in BTC. I'm planning to basically forget about it and let it ride for 10 years or more. It wouldn't hurt me if I lost it all, but it would be nice if it did well. Is this a reasonable strategy?
