Go to the ixquick.com search engine and search for “Bitcoin”.
There will be a number of search results that are for, against, and neutral with respect to investments in bitcoins. The basic concept of Bitcoin is based upon using computers to create the Bitcoin by solving a cryptographic encryption and then using cryptographic keys by computer to transfer the bitcoin to other people. There is a basic flaw in the concept which arises as the Bitcoin cryptography begins to reach the limits of its cryptographic sizing. There have also been some issues with exploits of the bitcoin authentication. Sovereign governments are also posing new threats to the usage of bitcoins. The search results discuss these and other problems.
Have you found any source of info on exactly what that cryptographic calculation is? I’ve not come across any mathematical or algorithmic description. If you find it please post it.
I only find people who want to sell hardware with some undescribed software.
