>For one encryption has been broken for a decade
maybe, but even silver certificates can be counterfeited and stores of physical PM can be robbed
No doubt there are vulnerabilities in crypto,but not necessarily just due to broken encryption. Issues related to attacking the very nature of the distributed consensus ledger are what scare me. You think it's all just a bunch of rando script kiddies running the computers that mine CC and process the transactions? Would it really be allowed to rest on the shoulders of some pimple faced kid running a miner in his mom's basement? It is reasonable to suspect that of the computers crypt is relying on are state machine farms. The wise have never bought that it was just an organic effort. It's white hat astro turf AT BEST.
And even if the encryption part of it was broken, just like even if tor or other "secure" network overlays are "broken" - (((they))) would never tell you. Chances are parallel construction would be how they got you/stole from you, IF you were valuable enough of a target.
It's also not unreasonable to believe that the point of crypt = digital transfer of real assets (gold, silver). Like precious metals, there is a finite amount of it in the world. And just like metal in the ground, all of it will never see the light of day. Crypto, just like gold/silver/whatever can be both lost, locked up indefinitely, or stay forever "unmined". I do not believe we will see all btc, for example, mined for an incredibly long time (certainly not in our lifetime), due to the asymptotic nature of mining due to the adjustable difficulty. Same applies to gold, we will never get "all" of the gold out of the ground; and the closer we get to getting it all, the harder it will be to get it (obviously).
Not to say crypt is gold or silver, but that it can be used as a suitable digital representation of gold or silver to make it useful for gold/silver based electronic and digital. Yet another nail in the coffin of fiat, which up to now has no actual digital representation. other than arbitrary amounts in a database.
