Building a Mining Rig or Invest in a Mining Contract????

When I look at investments, I look at them at things that are tangible; right here, right now. Mining contracts seem very skeptical versus having hands on a mining rig. With the same amount of money to setup a rig or a mining contract, I would rather have a rig! My reasons are as such: One, only God knows how long the mining companies will exist with a possibility of losing all your investments. And two, even if a contract or a rig is not profitable, at least you can get a return on your investments when you to sell your rig. It's all a risk, no reports of successful moon landings, let's keep our fingers crossed.
