It's a bit too late to invest in BTC mining if you're starting small though, I suggest you go with gpu mining, or better yet go with Proof of Stake. It's basically "mining" by just owning a number of coins in your wallet. You can start staking coins like Deep Onion, the current network right now has a very high payout (around 10%) per year. You don't need to have expensive hardware, gauge the cost of electricity and most of all better ROI.They have a pretty good community with tutorials on how to start staking, so better check it out!
Thanks for the info, that's very helpful.
