I follow all the scrypt coins news to see what's going on because I currently use various Antminers to mine coins. After gamecredits price fell to under $2 million marketcap, gulden was the only coin providing better revenue for scrypt miners on pools. I was sad and shocked to read that Gulden is changing Algorithms. This can have serious consequences for the Scrypt mining market and as such have already starting selling my miners on various auction sites.
Why didn't the Gulden developers approach the mining community to have dedicated hash and we could of supported the project in our own way. On the exchanges and withholding earnings from the exchanges?
Scrypt miners have killed the goose that lays the golden eggs, because they only interested in getting BTC or LTC rewards to exchange into fiat. Traders don't need to buy coins
on the exchanges, they can place buy orders and wait for the pools to dump. The miners should of been more pro active in supporting the coins they were mining instead of
expecting an indefinite income. It's too late to convince Gulden developers to stop with SIGMA but you can try salvage the situation with coins like gamecredits.
It's a free world, miners can cash out to whatever currency they want! Miners do enough for the coins by securing the block chain.
