It is still highly debatable
I don't think that the market cap growth of blockchains shows us or proves to us anything in this regard. Basically, it just reveals that speculation has increased a few orders and basically nothing beyond that. Even if the market cap grows a few times (orders) higher, it would still tell us nothing whether the cryptocurrencies would survive "in the wild", so to speak, i.e. without fiat sticking around (personally, I think that they will but this is just my opinion). Nevertheless, while the market cap has nothing to do with these questions, real adoption by the population of a specific country certainly has, and in Venezuela we are well on the way there. As to me, such real world test would tell a lot more than any figure like market cap might ever tell whatever it could be
