You got to understand something that happened to Andreas Antonopoulos a while ago to understand why he might have made the decision to hodl and not spend his coins. A few years ago Andreas Antonopoulos announced that he has almost no Bitcoins (BTC) and people roasted him on social media.
I think it's not that he didn't invest early on BTC, but he says that he got out of debt through his bitcoin holdings. And then after hearing this, individuals start donating to him and it went as high as $1.5 million, if I"m not mistaken.
I can understand that he might now be hodling coins as a result of that... not that he has anything to proof to anyone... because he is wealthy in knowledge and experience and that is more than money can buy. 
Of course not only Andreas, but even majority here holds at least some bitcoins in their wallet for years now. And just spend their fiat, and if they don't have fiat in hand, maybe they can just withdraw some btc->fiat.
