Cryptocurrency crash will hopefully bring expectations back in line with reality. Legit blockchain projects will only have to deal with the stigma from being associated with a giant pump and dump when they approach VCs.
I also think that behind the scenes on wall street there are some interesting things around securities settlement, something that is very time consuming and it's handled with some antiquated technology.
If securities trades are settled faster and ownership is more easily verified it could lead to some very interesting shareholder voting behavior.
The problem with all of these is that it requires a deep understanding of the process and the nuances of the industry to build a DLT solution that works.

Because viewing ads is voluntary, and users receive a tradable token in exchange for it, it lets you put a price on attention. The idea is that below a certain price of BAT on the exchange, users won't find it worthwhile to view the ads, and so they won't, which limits the amount of BAT users will sell, eventually forcing an equilibrium. That equilibrium price is the value of the attention that ads cost them. The price then carries over to the amount that buying ads will cost an advertiser, and the amount that publishers receive for them. Basically, they're rectifying an externality by throwing a tradable token at the user: instead of advertising being a transaction simply between advertiser and publisher, it becomes a four-way transaction between advertiser, publisher, user, and Brave itself.
None of this is possible without a dedicated currency, because the currency's other uses would factor into the market price, making it impossible to get a clear signal for how much users value having their attention taken from them.
