Well, as to whether miners are going to earn money every month or not, it's not really something that someone can completely identify because of a number of factors that there are different. There are a great population of people mining out there in different places of the world, the number of people mining is humongous right now already. there is no any specific guarantee that could come from anybody that can specify that as a miner you must earn every month.

However, not earning every month does not really mean that you cannot even be big in the Bitcoin mining industry. All it takes for you is for you to be able to join a great mining pool, I think that is better than you just being a Solo Miner.

So that when you join a mining pool, you have the opportunity to be able to do more creative things within the circle and industry, and as well you need that funding to be able to do quite a number of things, for example, an affordable electricity, to earn rewards that you are planning or that you are aiming in the mining industry even if it is not monthly though.
