> Cryptocurrencies solve the issue of trust.

I would argue it's closer to the opposite. Cryptocurrency solves the question, "How do you operate a shared ledger in the absence of trust?"

I, sitting in my cushy home in the USA, with my cushy American, NCUA-insured accounts at a fiscally conservative credit union, don't have that problem. I get to benefit from a regulatory environment that has done a quite good job of directly solving the problem of trust for the vast majority of its participants, so that we don't need expensive, complex trustless cryptographic ledgers to manage our electronic assets.
