Porn and gambling will help bitcoin go on mainstream as well (especially porn) but I'm worried bitcoin will be also the criminals' future. 
i agree. the criminal part is worrying to me too. and especially in the media, they have a tendency to show bitcoin as criminal money which is never helpful.
Bitcoin is money. Criminal part is always there when there is money transaction so that is normal. Bitcoin will involved in all matters that a fiat currency involves too with certain exception.
