That is indeed the game we are playing. You'll get a different answer to that question from everyone that answers it, and a good portion of those answers will likely fall into the category of dis-information. Everyone has a bias of some sort and some can't help but to try and steer readers in a direction that profits themselves more than the readers.

The most profitable advice given to me was to try everything (pool, solo, pick one coin, try lots of coins) and see what works best for you. Everyone has different resources to invest, costs to maintain, and expectations for the results, and differing amounts of patience. The best advice I have been given is to do the research on the different coins and only support the ones in which you truly believe.
