I looked into building a rig, but I was smart enough to read carefully about it and realize it was really not worth it. I even considered buying some bitcoin at the higher price because it seemed it could go much higher.
Now it has got to a point that mining is quickly becoming unprofitable. People are starting to realize that these coins do not have a high value and the explosive growth will not last.
One thing I realized is that it is very difficult to make easy money, and if it is easy it will not last. My predicition is the price will fall back to around $5-$11 dollars, and it will grow steady from that point. At that price level it is an OK investment, giving the high risk of bitcoin being worthless.
In the USA the dollar is a much more stable currency and it is far easily used in this country with much less exchange risk. The only thing bitcoin will be used for in the USA is the black market.
When do you think it will fall to $5-$11?
