Mining profits or reward has nothing to do with bitcoin being popular and will never change anything for the largest mining companies, they will always get their profits, this is something proven by time and even though halving happens only crazy thing is the race between miners and them adding mining machines day after day and I think this was intended by satoshi to make people actually do hard works to earn bitcoin to make it more fair whether big or small you need to consume electricity and resources, so for those people thinking bitcoin comes out of the thin air should think again.
