Something needs to be done to secure the network, whether that be POS, AUXPOW or a hybrid system.

GLC has an extremely low network hashrate compared to the scrypt hashing power out there now. The threat of a 51% attack is very real. With daily trading volume often less than 1 BTC and very little buy support on exchanges I would say the only thing protecting GLC is that there's really no point in wasting time and money on such attacks.

If we introduce AUXPOW there's still somewhat of a hurdle and that's getting pools to include GLC. With POS security we'd only have to rely on GLC users having their wallets running to protect the network and with POS interest they have incentive to do so. There's also the hybrid POW+POS option, look at peercoin, diamond etc. In POW+POS case changing to an asic resistant algorithm like groestl may be a good idea?
