Ok, So I'm a newbie here and recently just been reading and watching and learning all that people have to say. Like most people I thought, I'm going to make so much money from mining... Wait for it... Yeah right. So I've been mining for about 2 weeks (give or take) and have mined and successfully transferred .20 BTC to my wallet at
CoinBase (which i love) I got to thinking, calculating and kicking around some ideas. I'm a money type person, I love the stock market (I day trade daily) and will basically do what I can to make an extra buck, and in my eyes mining wasn't good enough nor quick enough. So what I decided I would do, is buy USB Block Erupters in bulk (lower cost per usb) and sell them on a smaller qty sale (higher price) With this method, I netted 62% ROI. All in about 2 days. So you don't have to be a mathematician to know that 62% ROI on anything is amazing. Much better and much quicker than "Mining" or Buying and selling Bitcoin... Okay maybe not selling bit coins, i guess it depends on when you bought.
Now, with that being said, I'm not saying that I don't mine. I currently have 3 9-port USB Hubs running 27 Block Erupters and a 8.2 GH/s Jalapeño for a combined effort of approx 16.5 gh/s. I will most likely add more to the collection on my buying and selling of Block Erupters and soon to be Fury's.
Lastly, I am a developer. I currently own and operate a software company (in which I will not be providing a name for) I was thinking about writing an app for iOS using the coinbase API..
Well, thats a bit about me. I'm still out looking for a reputable and reliable supplier in which I can get my hardware from (to keep and to sell). I hope that lends some insight on how I made money off of block erupters given todays difficulty
