Almost a cliche, Bitcoin is forking. I am not sure of the exact number but there seems to be a new fork mention every few weeks. Has anyone really improved on it?
improved on what? on making more money out of thin air? no not much, they are still using the same techniques for making a fork and copy pasting the code from bitcoin and other projects to make their own coin, usually add a premine, release and make profit. move on to creating the next one and abandon the previous.
