people mine at lose are gamble
they think those coin will to the moon someday
I know what you are trying to say but you are incorrect. People mine at a loss either because they are stupid or because they are trying to hide their acquisition of the tokens/coins (for whatever reason).
If they're gambling, they're doing it wrong. They are essentially tipping the power company for each bet they are making - it's a waste of energy and resources. If the coin moons as you say, it's always better to have more coins (which is what would have been achieved if they bought instead of mined).
