I doubt bitcoin will be more mainstream as many people imagine, because until now, users of bitcoin just focus on finding ways to enrich themselves and seek to benefit from bitcoin as much as possible, they do not care about popularity bitcoin and very little is started bitcoin introduced to a new person.
Trying to make a buck is human, I won't censure people for that.
Actually, that makes Satoshi look indeed remarkable. His bitcoins made him rich, but he hasn't really touch them. If the ones generally considered as his bitcoins are indeed his bitcoins, they are still seating on the same address since the beginning. What a difference between Satoshi and almost all the creators of alt coins.
