**DISCLAIMER**
The method explained here led to me being permanently trespassed from a best buy store. I PROVIDE THIS INFORMATION FOR EDUCATION PUTPOSES ONLY .
The concept is simple as can be. Go into every retail store that you can find the biggest baddest gaming rigs with the crazy high end graphics cards and setup a crypto mining software. Now you obviously should do this as discreetly as possible. But it can be done prwetty fast. I tried a few and found that Cudo Miner. Is the best tool for the job its simple to use and you can monitor your miners all in one spot. Happy ming and remember who graced you when you make the cash outs!
