The high mining fees has discouraged many gamblers and investors from investing into casino and other bitcoin investment opportunities. I am advised platforms builders to start open there business to other coins in other to not allow crypto currencies investment closing as many gaming websites has stop accepting bitcoin.
In that sense, for gamblers (especially low rollers) using CLAM is much better than BTC. CLAM fees are basically 0, as block are nearly empty. However they may have to transfer first BTC to Poloniex, so in that case they don't save anything in fees.
