I'd say go for it.  There are several things to keep in mind though.  If you are looking to make a quick profit it would be better to just buy currency and wait a month or two for a 10-30% ROI.
However, if you are like me and enjoy the mining experience then you can do like I did.

I started out with 1 GPU rig of 6 480RXs.  I reinvested all of the revenue and I currently have over 80 GPUs.  My electric bill is over $700/mo.  My GPUs are bringing in nearly 4,000 a month.  However, Instead of cashing out or taking any profit i've been re-investing for hardware.  It's been an amazing journey over the last year. Not bad for an initial investment of $3000.  I now have close to $24,000 in equipment.  I wasn't in this for the money, just the experience.

The point of it all imo, is to have fun.  Re-invest all your profits and just see what happens.  My personal goal is to have 3,000 GPUs mining from the initial investment of $3,000.  Note:  I do pay the electric bill out of my pocket.



That is all.
