    [...]

    Blockchain technology is often centralized. Bitcoin might
    theoretically be based on distributed trust, but in practice, thatâs
    just not true. [...] With bitcoin, there are only a few miners of
    consequence. Thereâs one company that provides most of the mining
    hardware. There are only a few dominant exchanges. To the extent
    that most people interact with bitcoin, it is through these
    centralized systems.

    [...]

    Do you need a public blockchain? The answer is almost certainly no.
    A blockchain probably doesnât solve the security problems you think
    it solves.

    [...]

    Honestly, cryptocurrencies are useless. Theyâre only used by
    speculators looking for quick riches, people who donât like
    government-backed currencies, and criminals who want a black-market
    way to exchange money.
