It can't succeed. Cryptocurrencies might succeed, but not bitcoin. It's not even inflationary; it's a cross between a payment system and a pyramid scheme.

Its a bit pedantic, but please don't say bitcoin when you mean cryptocurrency, as bitcoin is a pretty bad one.

> It's not even inflationary

And that's exactly the whole point, and is the very reason it's working.

> a pyramid scheme

Then every other successful investment is a pyramid scheme. Gold is a pyramid scheme! Storing food for catastrophes is a pyramid scheme! Paintings are a pyramid scheme!

Not every investment has to be a pyramid scheme. If you are generating value or selling a product then you end up with more money than what your investors are putting in.

What makes bitcoin into kind of a pyramid scheme is that right now a big part of the reward for miners is the 25 bitcoin you get from mining a block. Only a very small fraction comes from the transaction fees. The only way to keep bitcoin stable is by having a constant supply of new users buying into bitcoin by acquiring those fresh bitcoins from the miners.

Maybe a naïve question, but are there any good ones we should support instead?

I don't see a world in which Bitcoin would safe even only a single person in the traditional banking world. Bitcoin can neither replace banks nor creditcards. It might replace the ACH.
