How do I get bitcoin? Currently there are several ways in which you can harvest digital currencies and amass your bitcoin wealth.
The first is mining which is the most prevalent method of gathering bitcoin and other like currrency units. If you are just getting in, you are late to the party and it will take a great deal of effort and capital to catch up. Although the price per Gigahash per second (GH/s) is dropping significantly, the growth rate of participating GH/s is rapidly turning into terrahashes and projected to soon move into exahashes.
The drop in price can be attributed to a faster ASIC chip capable of doing many gigahashes than each of the predecessors. First CPU, then GPU, then FPGA, then 25nm and now soon to be 68nm chipset providing 200, 400, 600, etc. GH/s units at a fraction of the cost.
The problem is that the industry is outpacing the technology and preorders cannot keep up with the growth in mining. So what looks like a great deal and great ROI today turns out to be a flop when the technology actually hits the market due to saturation and degree of difficulty.
