Re: What to answer when asked "Can I make money mining bitcoin?"
You may make money, but that will take time, and it also depends on the electricity bills in the current area. If the electricity bills are relatively high, you can get bitcoins through purchases. But I personally think that mining Bitcoin will make money, but you have to spend a lot of time, energy and even money.
it can cost high electricity unless you used a very heavy equipment for your machines to mine. If not probably it will not consume but less profits as well.. Because as far as i know mostly provide very expensive hardwares for it in order to have good profits.. So if want to build mining and wants good returns from it then make sure you can afford to provide those important things in mining.. Its like investment as well to be honest. 
Best to have a better knowledge calculating everything before you step in this investment plan.
