I'm sorry to say it but probably 85-90% of the traffic is because of greed.
All those signature campaigns, giveaways, airdrops some sort of "free money", attract more and more people who have come here to "work hard" and make as more as possible.
Then comes the bots, alts and scammers, together with the FOMO-ed newbies trying to invest now and be rich in a year, because someone told them so but got fooled very easy and then shouting around that bitcoin is only for criminals, it's scam, ponzi, bubble etc...

At the end we are all here only for the technology :
