What they need more then plain maths reflecting past and present scenario is the imagination to see the trajectory of Bitcoin is not linear.   If BTC were to continue in gains of multiple orders of magnitude it negates the idea of being restrained by a withdrawal limit exactly.   Or put it historically, was the withdrawal limit always 30k sats because that was pocket lint in years past so my guess it was way higher.
  The problem is not that people think and consider the maths of the situation but they fail to continue thinking for more then a moment.   Maybe the ideal referral source is from a forum of people who are willing to dream, imagine, believe.      I dont know where that place might be exactly, maths can describe all sorts but also it can be misdirected to an incorrect conclusion.
  Imo you could just collect the faucet and not regret it, also its fair to assume if BTC were growing then it makes sense to be far more involved also.   Persistence of vision is a big deal in many subjects, hopefully BTC doesn't levy a high bar especially in terms of insight required.
