So. This is mostly an opinion/observation thing. I want to touch on a few topics in it, in preparation for a big project I'm working on. Think of it as a "primer". As such, let's get started.
If there's one, most common point of failure among great ideas, it's a bad user experience. What do I mean by that? An experience in which the user gets annoyed, dissatisfied or downright frustrated by the product. If a product leaves the user/customer in a such state, they may never return to it. This is why it's so important to have a coherent, easy to use at the top user experience.
Using BCH as an example, loads of people here are just more experienced with crypto in general.
But, we must remember that adoption of fresh, new users is as important. As such, those users should have an easy to use and clean gateway to the ecosystem. So far, that gateway has been the bitcoin.com wallet. It isn't an ideal gateway, it's far from that, but some of it's qualities make it the best for a newbie to use out of the available options.
User experience, in terms of cryptocurrency, would relate to multiple things, such as: how easy it is to send it, what can you do with it, how secure/safe it is, and how can you interact with it (wallets etc). A bad user experience, be it due to high fees, long confirmation times/non-secure 0-conf, a lack of good wallets or a generally lack of features will definitely make users unhappy, and thus not interested in a project.
This is why user experience is so important. If UX is bad at a moment where a potential user tests it, they won't usually look back. They will instead use something else, usually a competitor.
But, in a more general sense, user experience relies on a fair number of things. A good user interface for x product/project is very much one of them, among others like a good lifespan (so updates and such), stable operation (no bugs etc). All of those factors add up, and while some might be 100% pristine in a product, one major flaw might decide it's "life". As such it's very important to make sure that everything works well, and not focus on one thing only. A good technical specification and inner workings WON'T replace a good user interface. Because sure, your x thing might be the most powerful of it's kind, but making it only for Command Line Interface will make 90% of users disinterested, unless you target a specific niche that can accept CLI. Within cryptocurrency in general, the biggest issue is usually a lack of a good UI, but some ecosystems like Ethereum have mostly managed to create quite good solutions. But let's not get ourselves ahead here.
And that's all for this one.
See you till next one.
Excellent points. I would suggest that, in terms of technology revolutions, we're at about the same stage in crypto as 1978 in the PC revolution. Only the hard core geeks had one. The legacy option was huge, expensive, and tried to pretend it was just a fad. There wasn't a lot you could do with one. The options were vast, underpowered, and most would disappear. Most people had no clue about them but everyone was talking about them. But just a few years later... Boom! User Experience is necessary to sustain the boom.
