People need to use cryptocurrencies. We need to encourage its use. They need to spread it and talk about it. Have this expectation that only the financial market can be considered for the Bitcoin becomes popular is absurd.
Bitcoin was made to disruption the financial institutions. And not to be just another asset used by banks and speculators.
However, it had become the best speculative assets and people tend to forget what Satoshi wanted it to be, to be used in real life situations just buying hotdog as someone has pointed out. And Satoshi's white paper is aptly titled:
Bitcoin: A Peer-to-Peer Electronic Cash System
One could argue that because of the scaling issue, bitcoin can't be a electronic cash system and proponents of Bitcoin Cash is pointing this out, but I do believed that it still be used as originally visioned by Satoshi, by having Lightning Network and Segwit adopted by merchants and bitcoin enthusiast alike.
