It depends if they're indeed "using it", some are just bagging cryptos and never get to fully utilize it. I can understand that part for people investing in Bitcoin. Some would be entirely for investment purposes like only for the sake of "hodling". Some are using it for currency and of course, some of those people are in the dark web using it for some....stuffs though there are people here in the surface web like me using it also for buying completely normal stuffs.
