[Cryptography] Bitcoin theft and the future of cryptocurrencies

>>> We already are facing big trouble over scaling.
>>> Zerocash is too damned slow.

> Last time I looked, could not handle bitcoin scale.

> What does Zcash scale to now?

Too many areas mixed together in above.

>> https://z.cash/ shows near term updates coming that significantly
>> raise performance.

Meaning zcash sapling for client side performance.

As with "new" crypto of zk-snark,
where are analysis of the new curves in sapling? ie:

Many other coins are now roadmapping cryptographic privacy
such that if the architecture of "Bitcoin" ends up sucking, say in
tx/s, blockchain storage, or features, the others might succeed.
It might be at least another 5-10 years before some model
shows up with acceptable / provable "scale" that is thought to compare
with even the relatively short lifespan of all known fiats to date.
Probably better to consider ingraining in culture that currencies
are now better exchangeable / swappable / pluggable, rather than
continue the lunacy that there should be only one for all time and uses.
BTC may be the first to prove that smooth mass migration and abandonment
of failure, with little physical war or asset loss, is the new workable model.
