Well - Bitcoin for me personally was not just about getting more money than I spent on it… it is more about the principal for me - a censorship resistant means to financial sovereignty, which is more important than maximum profitability. With regard to Smart Mining on ViaBTC - it is NOT merged mining, it allows you to use auto profit switching where the poll will stop mining one and start mining the other if one of them spikes in value / mining difficulty, rendering it substantially more or less profitable than the other. NMC / SYS is legitimate merged mining where you’re accumulating all of the above at the same time.
