I'm contemplating investing in umisoo, because the buy-in price per GHS is so much lower than S5, offsetting the higher maintenance fees.
However, maintenance/payout is already at 88.91%, so not much headroom left til 100%...

Does anybody have an opinion of whether I should go for it, or stick to the regular S5 plan?

Cloudmining is a must for me, electricity in Belgium is way too expensive to make physical units profitable...
