[MCU] Why did Thanos task a bunch of smaller villains to gather the Infinity Stones when he could easily do it himself?

It seems like a risky idea letting others handle objects that grant God-powers when all held together. 
With how easily Ronan turned on Thanos with just one stone, what would Thanos do if more of his lackeys wanted to keep their stones or if ONE of them managed to get the majority, or even ALL, stones?

When Thanos moves, the galaxy watches.

Thanos is powerful.  Far too powerful for any single galactic Empire to defeat.  But, if he were to *use* that power, he would be vulnerable to one of his many enemies deciding to use that opportunity to launch a surprise attack.  He could use the combined Infinity Gauntlet to fight off all his enemies simultaneously, but he needs to be able to *get* them quickly.  

Throughout the buildup movies, the Infinity Stones are hidden more than they are protected.  The main point of his minions is to find them.  Actually staying loyal and retrieving them would be nice, but it isn't necessary.  For example, Starlord finds the purple one on a dead planet, and Ronan takes it from him.  At the end of the movie it's being protected by Xandar.  Thanos can handle Xandar, waltz into their most secure vault and take the stone, but he can't waste time on what might be a wild goose chase searching a dead planet for the stone.
