Yesterday I released v2.1 of SATSuma, my little project that keeps on growing. The latest release has too many additions and improvements to list (although I have listed them here! https://satsuma.btcdir.org/version-history/)

One of the new features is a DCA calculator, pictured below. SATSuma is free and open source, bitcoin only, and (sorry) Windows only.
