You can make real money on the long term if (1) you are a platform (ie. aggregator) or (2) you are very small (i.e. blogger/vlogger). Anything else will be eaten by software.
I am now finishing my sub-chapter on aggregators and I thought why not share the obvious: eMAG as a Service.
Bold, time consuming, cash intensive but so rewarding in the end (if done properly).
