there are hundreds of video's
the problem is what level?

some are for noobs, talking about bitcoin using gold analogies... some are technical using long works only geeks understand. some are based on financial businesses some are from libertarians talking about freedom of money..

it all depends on what style, demograph and subject you want..
but a good start is just to youtube search and see what you can find
