Eventually, my droid will start buying the entire stock of wholesalers, then wholesale companies themselves, and emerge is a highly formidable competitor in the internet marketplace. As soon as his/her own auction site, store sites, etc... are launched, many people will start using it, and other by-then-minor auction & store sites will get bought out...
But the chain reaction only goes so far, unless...
With many other androids helping run the business, which even has its own android factory by now, s/he will just keep helping me get richer and ever richer.
The business growth will eventually hit a wall, unless the robots invent/innovate anything that increases efficiency, cuts costs, and explodes even more profits. They certainly will, and at lightning speeds, several orders of magnitude faster than humans can.
Still, that won't be enough since my orders were to make as much money as quickly as possible, so to gain more customers, my next duty is to introduce backwater & developing 3rd-World countries into the First World.
Introducing ALL 3rd-World countries into the First World through Androidal help
Once I'm in the mega-big leagues, I'll become even more charitable than before and buy millions of androids in order to donate them to needy parts of the world, so they can give the help and build all the infrastructure needed to enter the First World. Due to their ultra-fast pace of work, self-learning, & self-improvement, the entire world will enter the First World in less than 2 months.
