Miners in Proof of Work currencies that find a block can choose what transactions in what order get mined. Through which they can change the order of operations

Miners in Proof of Work currencies that find a block can choose what transactions in what order get mined. Through which they can change the order of operations, but they can’t invent transactions or manipulate them directly. I have found the issue of miners and transaction manipulating to be overblown.

They could block, and may find themselves required to block transactions from unknown sources if this space becomes more regulated.

  Solution to this is privacy-based wallets and/or second layer payments (e.g. lightning network).

    Lightning is a joke. A really bad one that keeps dragging on. Production ready in 18 months! Forever...

      What do you mean? it's already in production.
