You seem to be new around here so firs of all, welcome!
Be very careful about mining. In essence, solo Bitcoin mining is about 98% unprofitable today unless if you don't live somewhere where you get a free electricity. This is about mining if you want to rent your or buy your own hardware.
Cloud mining as well. There are maybe 1 or 2 businesses that do it right out of 30 out there. The rest are very likely a scam. Even with these 2, you won't make much. Better look to invest in some other way in Bitcoin, not mining.
Whatever you decide to do, double check even triple check everything, do research, ask questions on this forum so that you don't get scammed.
