This discussion has lead to a really interesting point, actually! The replicability of Bitcoin has always been a high concern and also point of critique for many people who aren't convinced of Bitcoin's usefulness. I also believe that Bitcoin and Gold are quite similar what this is concerned, as both their scarcities could be attacked and circumvented at some point!
i agree that gold and bitcoin are quite similar, but with bitcoin you exactly know the amount that ever will be mined. not the case with gold. also important is
that bitcoin has way more room for growth compared to gold.
I agree, but you have to keep in mind that Bitcoin is a very new kind of asset and it is not clear whether it will "succeed" in gaining more traction. Also, the encryption algorithms and one-way mathematical functions could end up being faulty and there may be no replacements, if quantum computers become feasible in solving arbitrary problems. This is something we can't possibly foresee right now.
