[this video] Not that hard to do. Just a matter of perseverance and a bit of luck. Yes, it could be faked, but I trust him.

It's a little worse than that as there are vast incentives to be that guy with 20 heads so people will record themselves fillping coins over and over then only talk about their best streak. Thus you end up with most companies having an 'above average' streak in a given year even if the average investment does poorly. [this video]

Spot-on predictions! If I predict this coin flip will be heads, and I flip it, and it is heads… does that mean I can predict coin flips? What if I do it three times in a row? What if I do it 10 times in a row? [1] [1]: [this video]
