In the years to come ENERGY WILL MATTER FOR EVERYTHING so using less of it is needed.

guys at the top(btc miners,nxt shareholders) will always make a killing so the most efficient and less energy sapping system
for the masses is best.

I thought LTC was faster than BTC to use but NXT is even faster.

Of course, you will have to get your wallets out folks.....the MIGHTY 'NEM' will be arriving soon......DONT MISS OUT  !!!!!!!!!!
