    Sorry for your loss, it is realy bad that so many people lose money this way.

    I think centralized exchanges will be replaced in the future with transparent decentralized ones.

    Thanks for the condolences! ;) I tell myself I'm mostly over it...

    This is how I handle private keys these days...

      Looks good, but dices are not good random number generators, because they are not identical in size and they might corrode which can be modeled mathematically.

      The numbers should still be unknown, except if the attacker finds some correlations between the dice's shape and the numbers it gives.

      I think even a tainted hardware RNG is better than a dice, but I will write my next article about this, because it's an interesting subject, that is not well discussed.

      Casinos use dice all the time, and they are quite serious about money. I understand that there is no "perfect" source of entropy, but as sources go, high-quality casino dice are very good...

        Yeah but nobody will spend time and effort to send a bad dice to a casino, because the casino can easily detect if their dices are not good.

        But if the dice is used to generate electronic entropy, then someone might boot up a supercomputer and search for autocorrelation in your BTC public key that had bad entropy. it makes your public key less secure, and why would you want that? It could be vulnerable against quantum computers when the come out.

          Thank you for the "shout out" link to my dice article from your article on private keys.

          I guess we'll just have to agree to disagree on this one. I will continue to believe that computers are far worse as random number generators than a good pair of casino dice.

          Here's a good source of information on randomness that you might find interesting:
