Hello guys,
Probably going to be met with eye-rolls and "noob!".... But anyway, I'm brand spanking new to, and still pretty intrigued by cryptocurrencies and how they work. I have the basics down, I've done some research and I think I'm ready to start mining for bitcoins. Since I don't have the resources available to me to efficiently run my own hardware, I think that cloud mining is a better fit for me. I started an account on GenesisMining, and was instantly met with terms like Th/s, Gh/s, Mh/s, and other things that make no sense to me, with no explanation.

Can someone who is an expert or at least knowledgeable please give me a good recommendation on what the best cloud mining service is, and at what rate I should mine for the most cost-effective results?

(I do not plan on using cryptocurrencies for any unethical or illegal purpose.)
