Let's not make the line between investment and knowledge too extensive. One can invest with out proper knowledge of what he or she is investing on and one can still have a proper knowledge yet not invest. It's vise visa.

If you have the capital why not invest and long the line of your investment you are learning already. Some people invested in bitcoin with out a proper knowledge all the knowledge was how to buy bitcoin in an exchange along the line of having bitcoin somewhere they got interested in knowing how to maximise the opportunity they had which is the learning we are talking about hence the knowledge is in the process of purchasing.

Some benefits of knowledge about bitcoin or having a proper knowledge of it is just be sharing your knowledge or teaching people about it for payment, just as we that participate in a campaign we are examples of people who benefit from having bitcoin knowledge before investing in it though I'm not generalizing this statements because some invested before finding the forum.
