Hi guys i'm a very newbie in BTC, then, if you don't mind, i have a question since there's something sound strange.

Let's say i buy the best miner (actually i think it has 14th/s hash) at the price of 1500usd plus ship, other parts, etc...let's say i pay it 4000$.

Then i see in many websites, with such investment, i can get up to 700$/month. It's around 200% return annual.

The question is: why invest in industrial machines, restaurants, homes for rent, and any other activity, once you can buy (with the same amount) 100 miners and earn milions in few years?

It's strange for me...can you illustrate me if is there any error?
