You mean the main argument in the Bitcoin bubble video. Yes, people are certainly using cryptos to send stuff. I use Bitcoin to send money every month or so, and sometimes it's certainly convenient to send it that way. However, I certainly wouldn't hold as much bitcoin if I didn't expect it to increase in price.

Perhaps she overstated the case a bit, but I'd say the housing bubble analogy could be accurate. People still use houses for living in - even the majority of people do so. That didn't mean that housing wasn't in a bubble. Time will tell.
