What could convince you, as a skeptic, that crypto currencies are a technological step forward and deliver value to humans?

A use case that delivers positive value (i.e. not just enabling crime). I found some of the cryptokitties-style experiments interesting, but not when every transaction costs $50 (and the security of the chain only works if the underlying "coin" has value, so that seems inherent and unavoidable).

I suspect most people won't understand the value until they immediately need the privilege of using it--a privilege which anyone with a computer has, but no one is required to exercise (unlike every other national currency).

Needing to use bitcoin isn't going to be experienced as "privilege" but hassle, imposition.

You must be in a time machine. The security does not depend on underlying value (that's proof of stake), it depends on hash power, which is not a function of value, it is the input to the value function. If the value of the coin dropped then hash power would decline, but the rewards for out-hashing someone would also drop - it wouldn't affect security, you're all mixed up!

The coin rewards would drop, but the rewards for being able to steal whatever else is running on top of the chain stay the same. So to be secure the layer 1 chain has to stay more valuable than everything else that's being secured on top of it, otherwise it becomes worth doing a 51% attack on the underlying chain to get the stuff on top.

I would like to buy a sandwich in the grocery store I go to on lunch break. It's already been 12 years, guys.

It's like when religious people say: "Jesus will come again, but he may tarry...".

You don’t pay BTC for the same reason you don’t pay for sandwiches in gold ingots. It was never really about daily payments. Probably the closest sandwich payment method is those crypto backed credit cards. Or you could buy a sandwich in El Salvador, and pay via the Lightning network.

That's great man, you'll be a convert eventually! But if you wait until the steps are laid out for you easy as pie, you'll miss the speculative gains! At least you can say you followed the rational doctrine!

Oh what's that? You really think 12 years of development is too long to buy a sandwich. Well if that's an issue for you I recommend you look into this thing "Quantum Computing." They can't even make those things do calculator math and its been forever. Sheesh.

At least or better carbon parity than existing systems, feasible transaction rollbacks when mandated by law. Sorry, not willing to accept these bugs as features. /gen
