Oh well, we really cannot take that away from them since they have invested in materials just to be able to mine and they have already learned to love what they do. Of course I am sure that you will probably be feeling the same if you were the one in their situation. As an investor and a lover of cryptos it will be something that a miner will really feel. Specially when he already sees mining as a full time job for him. I can only imagine how heart breaking it would be for that person.
