Only for the entertainment value. I stopped mining Hiro around diff 1. Mining at diff 100+ is throwing money away and just plain stupid, even if you believe the price will go up.
With the power cost where I am, mining Hiro is 3-4x more profitable than Vert, Doge, Dark, Litecoin, or even CleverMining which I was on before. Don't assume the case for you is the same for everyone.
Hiro is fantastic, I was about to turn off my rig until I found it.
