So most of the guys gave there opinions that do not mine individually they are right because by that you may not get anything.
Well if you are thinking about mining individually then you will need a very expensive equipment which will be really hard for a single person then after that you may mine some block and gets something.
If you mine as single person you will never able to mine the single for a month as well. Really waste of the time if you do like that. There are many people still mining the bitcoins with the GPU and ASIC hardwares.
If you want start the mining process, these both the other are start to work better and you will get the more hash power by mining it. Compare to GPU you will be able to get the more hash rate in ASIC miners. You can go to invest on it.
