I gotta help the new guys here

If you're a newbie getting into mining read this:

You may be reading about fantastic opportunities to earn by mining, but remember that if you order some miners which are delivered in the future - the hashrate difficulty may have doubled/tripled or even more before you even receive the hardware.

This happened to several buddies of mine last year. Equipment promises several 100 USD per day, when it arrived 4 months later the difficulty had skyrocketed and they got less than 20 USD per day. The price of the hardware itself also shrunk because people don't want the obsolete equipment.

They would have been much better off if they instead had just bought the underlying asset (Bitcoin, dash, Litecoin or whatever) and see the prices rise gradually.

Think - and do your own due diligence.
