SIGMA is a pure CPU algorithm which means I and many other Gulden users will start mining. Not many people will sell at these prices because the development is worth 100 times more than this, because the coin is on scrypt until this Wednesday only pools mine Gulden and auto dump on the exchanges.

The mining reward drops from 80 to 50 and the witness rewqrd goes from 20 to 30. Witness you might not of heard of because the marketing is the worst in the world. Witnessing is highly innovative. You can find info on https://gulden.com

The marketing of this coin is so bad that coins i used to buy are dead projects today and have more than twice the marketcap of Gulden.
