I just don't get it.... why people are getting into legal trouble with Bitcoin. How can they say you need a Money transmitter license for Bitcoin? What is the difference between Bitcoin and Swagbucks or XBox points? To me it's just a digital product with no need for Government regulation at all.
When buying used GPUs off craigslist find people that still have the box and packaging. Make sure the GPU looks in good shape from a recreational gamer and not overclocked. Most of the time people that save the box take good care of their equipment. Plus it's easier to resell.
