Which one is better: Mining at my own place or hosted mining (For a newbie)?
I will start with the fact that in both cases you have to know very good what you're doing. Hosted mining can easily scam you, since you never touch the actual miner; and if you by chance thought on cloud mining, that's scam from start.
Then, mining at home depends on the electricity prices in the fist place then on the fact the miner should stay in a cool, dry and clean place, with very good power wiring, good internet and, if it's too close to you then you may need to also handle the noise. Plus you have to research and learn a little, but people around here will help you with that part.
