I think back in the day, a quick pump and dump of BTC when it was say $100-$1000 range, was what brought in most people in the first place, that and it was kind of new, cool and relatively cheap(ish).

What people see now recently is that BTC is more or less flatlined. Most peopl dont play the lottery to win a few bucks, they play to win the jackpot, seems like those days are long gone in Bitcoin.
